Post-Production

You know that feeling when your smoke asset just sits there like a sad layer on top of your shot? No shadows, no light interaction.
Yeah. I was sick of that too.
Here's how to relight 2D smoke assets in After Effects so it actually reacts to fire. You get real lighting falloff, dynamic shadows, and it doesn’t look like you slapped it on in 30 seconds.
Here’s how you can do it using just two free plugins and a couple free ActionVFX assets.
You'll want to watch the video for a full walkthrough and to get the why behind the techniques I use. But I went ahead and put a summary of each step below so you have that for reference.
<iframe width="560" height="315" src="https://www.youtube.com/embed/pV8NCLWLefc" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen></iframe>
<h2>Step 1: Plugins You’ll Need</h2>
This whole trick depends on two things:
<ul>
<li><a href="https://bit.ly/normal-mapper-for-ae">Normal Mapper for AE</a> (free on aescripts—but I encourage you to donate to the creator)</li>
<li><a href="https://bit.ly/normality-plugin">Normality</a> by Stefan Minning (also free)</li>
</ul>
<h2>Step 2: The Setup</h2>
Everything I used is included with your ActionVFX subscription, but you can also follow along with free assets too:
<ul>
<li><a href="https://bit.ly/4jUWfJ7">Smoke Plume:</a> from the Free Smoke Plumes Collection</li>
<li><a href="https://bit.ly/3SC81fa">Practice Plate:</a> from the Practice Footage Library</li>
</ul>
You can also get the fire asset I used with the code in the video until May 29th, 2025. <a href="https://bit.ly/430OA64">Just input the code here</a>.
I set everything up in After Effects using an ACES workflow. If you're not familiar with ACES in AE, <a href="https://www.actionvfx.com/blog/how-to-use-aces-in-after-effects">we’ve got a separate video walking you through that</a>.
<h2>Step 3: Precomposing the Smoke</h2>
Precomp the smoke layer and call it Relit Smoke. From here, there are two ways you can go:
<ul>
<li>Option 1: Leave all attributes in Master Comp – better for static shots or stationary lights (like a fire).</li>
<li>Option 2: Move all attributes into new comp – better if you have moving lights (like headlights sweeping across).</li>
</ul>
For this walkthrough, I started with Option 1.
<h2>Step 4: Building the Normal and Depth Maps</h2>
Inside the Relit Smoke comp, duplicate the smoke layer 4 times:
<ul>
<li>Normality (top)</li>
<li>Depth Map</li>
<li>Normal Map</li>
<li>Texture</li>
</ul>
Each of these layers gets its own treatment:
<ul>
<li>Depth Map: Invert → Curves → Adjust until clipping shows in the highlights.</li>
<li>Normal Map: Precomp it, then apply Normal Mapper and crank the strength to 100. Add a Fast Box Blur (~1.2–1.5) to clean up artifacts.</li>
<li>Texture: Invert → Unmult → Invert again. Then adjust alpha with Curves and add a Tint to ensure grayscale.</li>
</ul>
<h2>Step 5: Bringing It All Together</h2>
On the Normality layer apply:
<ul>
<li>Invert → Unmult → Normality plugin</li>
</ul>
Set it to 3D (even though Normality doesn’t recommend it) because it gives you better falloff and placement.
Then assign:
<ul>
<li>Normal Map from the precomp</li>
<li>Depth Map from the comp</li>
</ul>
Make sure Effects &amp; Masks is checked.
Invert the Depth Map so thinner smoke appears brighter (as it should when light passes through it).
<h2>Step 6: Lighting the Smoke</h2>
Now for the fun part: lighting.
Create a Point Light, set it to white, and position it where the fire would realistically be.
Then duplicate it and move the second one to the opposite side for more natural coverage.
To make the lights feel alive (like fire), add wiggle expressions:
<ul>
<li>Y Position: wiggle(3,60)</li>
<li>Z Position: wiggle(2,100)</li>
</ul>
Copy those expressions to both lights. The result? Lights that move organically like a fire would—casting shadows and highlights across the smoke dynamically.
<h2>Step 7: Making It Fit the Scene</h2>
Back in the main comp, duplicate and offset the smoke to make it wider, covering more of the fire area. Relink the depth and normal maps for each instance.
You might notice the smoke is now moving too slow compared to the fire—so use Time Stretch on the precomp and set it to 30.
<h2>Step 8: Coloring the Smoke with Firelight</h2>
Here’s where it really sells.
Duplicate the relit smoke precomp and add a Fill effect to the bottom one (set to black for black smoke).
Then duplicate the fire layer, apply a glow (I used Deep Glow V2, but standard Glow works too), set the Source Opacity to 0, and then track matted the glow layer to the relit smoke using Luma Matte.
Boom. Orange-tinted smoke that shifts color with the flickering fire.
You could technically just apply a Tint to the smoke and call it a day—but doing it this way means the light interacts dynamically with the smoke, based on the actual fire movement.
<h2>Step 9: Bonus Lighting</h2>
Need moonlight on the smoke too? Easy.
Just duplicate your relighting comp in the project panel, move the lights to match the moonlight position, and drag the duplicate into the main comp. Hold Alt while you drop it on top of the relit smoke layer to swap them.
Set the blending mode to Screen, add a Tint, and now you’ve got moonlight hitting your smoke too.
<h2>Final Touches</h2>
From there it’s all about dialing it in:
<ul>
<li>Adjust curves, hue/sat, exposure.</li>
<li>Move lights around.</li>
<li>Edit the normal or depth map if something feels off.</li>
<li>Add glow, camera shake, you name it.</li>
</ul>
You’re not locked into anything. The beauty of this method is it’s totally tweakable.
<h2>Why This Method Works</h2>
You’re taking 2D stock footage and tricking After Effects into treating it like 3D volumetrics—without ever leaving AE, and without needing full-on simulations.
And if you’re working on tight timelines or client work that doesn’t justify the Houdini pipeline? This will save you.

If you’ve ever keyed out a green screen and ended up with your actor looking like they just stepped out of a toxic waste barrel — yeah, I’ve been there too.
That’s also a great way to make the audience go, “Oh... that’s fake.”
Which is also a great way to make your client or supervisor go, “Hey, you’re fired.”
So let’s fix that.
If you want your composites to look realistic, getting a clean key is non-negotiable. In this tutorial, we’ll walk through 5 key tips (pun unfortunately intended) for better chroma key results — using After Effects and Keylight as our tool of choice.
<iframe width="560" height="315" src="https://www.youtube.com/embed/L1_Wx-IxsAA" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen></iframe>
<h2>Use a Properly Lit Green Screen</h2>
Before you even touch your software, the most important factor in getting a clean key is how your footage was shot.
First rule: make sure your green screen is evenly lit. No shadows, no bright spots, no weird gradients creeping across the background. Just a clean, flat green. Uneven lighting is one of the biggest causes of fringing and artifacts during keying.
Next, think about distance. The closer your subject is to the screen, the more green spill is going to bounce onto them. By giving your subject more space from the background, you cut down on that glow before it even starts — and your keyer will have a much easier time.
<blockquote></blockquote>
Bonus: Need some properly shot green screen footage to practice with? We've got a free <a href="https://www.actionvfx.com/practice-footage">Practice Footage Library</a>. It has several green screen shots to help you practicing keying and compositing.
<h2>When to Use a Blue Screen Instead of a Green Screen</h2>
In most cases, green screens are the go-to. They tend to key out cleanly in daylight scenes and play nice with natural lighting.
But there are times when blue makes more sense:
<ul>
<li>If your actor is wearing green, obviously.</li>
<li>If you’re shooting a nighttime or low-light scene — blue screens retain shadows better and preserve more detail in dark areas.</li>
</ul>
So if green’s giving you trouble, it might not be your fault. Switch colors when it makes sense.
<h2>How to Use Keylight in After Effects</h2>
Once you’ve got solid footage, it’s time to key — and if you’re in After Effects, Keylight is your friend. It’s powerful, free, and built right in.
Here's a quick breakdown:
<ul>
<li>Screen Colour: Use the eyedropper to select your background.</li>
<li>Screen Gain: Controls how aggressive the key is. Higher = more background removal (and more danger to your subject).</li>
<li>Screen Balance: Helps fix uneven lighting by adjusting the color channels.</li>
<li>Clip Black / Clip White: Fine-tune the matte edges. Clip Black removes leftover junk; Clip White locks in the solids.</li>
<li>Screen Matte View: Flip to this mode to see your alpha channel. It’ll show you what’s really being keyed — which is super helpful for fixing trouble spots.</li>
</ul>
Take your time here. Zoom in. Toggle between modes. This is where “meh” keys become production-ready.
<h2>Kill the Spill</h2>
Even with solid footage and a clean matte, green spill happens — especially around hair, fabric edges, or shiny surfaces.
<ul>
<li>Keylight has built-in spill suppression controls. Use them.</li>
<li>Tweak these after your matte is dialed in.</li>
<li>Desaturate or rebalance the edges to neutral tones.</li>
<li>Watch out for skin tones — don’t trade green glow for zombie skin.</li>
</ul>
<h2>Garbage Mattes: Not Glamorous, But Super Useful</h2>
Garbage mattes help your keyer focus only on the subject. That means:
<ul>
<li>Faster rendering</li>
<li>Less chance of noise and edge errorsFinal Polish: Matte Cleanup &amp; Edge Refinement
Once your key is mostly working, flip back to Screen Matte View and check your edges.</li>
</ul>
<h2>Final Polish: Matte Cleanup &amp; Edge Refinement</h2>
Once your key is mostly working, flip back to Screen Matte View and check your edges.
<ul>
<li>Use Clip Black/White to tighten things up.</li>
<li>Look for semi-transparent fuzz or inconsistent edges — especially in hair or fine detail.</li>
<li>You want clean, solid separation. No gray halos. No crunchy outlines.</li>
</ul>
This last step takes time, but it’s the difference between “that’s obviously keyed” and “wait... that’s composited?”

How to Fix Bad Green Screen Footage | Pro Chroma Key Tips for Cleaner VFX

You’ve seen it in blockbusters. You’ve seen it in high-end streaming shows. You’ve even seen it in commercials, trailers, and indie films.
You just didn’t know it.
That thing is VFX Stock Footage. No, not the cheesy kind with people with fake smiles drinking from an empty mug. We’re talking VFX Stock Footage: real, high-quality video elements designed for compositors. We're talking about real footage or renders of effects like fire, smoke, fog, rain, and debris that are built for easy use in visual effects shots.
VFX stock footage is one of the most widely used, yet least talked-about tools in VFX. And it’s not because it’s a shortcut. It’s because—when used well—it’s invisible.
<img src="https://a-us.storyblok.com/f/1002378/800x450/384711376a/rain_car_compv2.jpg" alt="">
Try to spot the VFX stock footage in this shot. If you can't, <a href="https://www.actionvfx.com/blog/after-effects-tutorial-how-to-create-realistic-rain-at-night">check out this video</a>.
In a recent video, ActionVFX founder Rodolphe Pierre-Louis breaks down what VFX stock footage is, how it’s used, and why the world’s top studios rely on it to meet deadlines, maintain quality, and stay under budget.
Here’s a look at what VFX stock footage is, how it's used, and why the world's top studios rely on it to meet deadlines, maintain quality, and stay under budget.
If you’re new to VFX, or a studio manager wanting to learn more about how your post-production works (or just wondering why these elements exist in the first place), this is for you.
<h2>So… What Is VFX Stock Footage?</h2>
It goes by a bunch of names—VFX elements, stock assets, compositing elements—but the idea is the same:
VFX stock footage is real footage or renders of effects like fire, smoke, fog, rain, and debris that are built for easy use in visual effects shots.
Usually they’re filmed practically. Other times they’re high-end simulations rendered out and prepped for compositing. The point is, they’re already built with post-production in mind.
You’re not starting from scratch. You’re starting from something ready to go.
<img src="https://a-us.storyblok.com/f/1002378/2000x1125/2d09b0068c/actionvfx-blood-vfx-bts.jpg" alt="">
<h2>Why Does Everyone Use It?</h2>
Here’s the thing: you could build every single VFX element yourself. You could simulate every flame, shoot every dust burst, or spend a few hours in Embergen tweaking ash trails.
But no one actually works like that—because it’s not realistic.
(P.S. That's true even when their marketing campaigns claim they did everything themselves. More on that later...)
<h3>Turnaround Times Matter</h3>
On real productions, time isn’t a vague concept. It’s a schedule. Deadlines are tight, shots pile up fast, and you need to move.
When you can grab a real explosion filmed from 10 different angles, comp it into your scene how you want it, and keep rolling? That’s a win.
<h3>Budgets Are a Thing</h3>
Even the biggest studios have limits. Simulations and FX-heavy shoot days aren’t cheap. If you can get the same visual result with a $100 asset instead of an $8,000 setup, that’s just good math.
Don't believe us? <a href="https://www.actionvfx.com/blog/godzilla-minus-one-vfx-oscar-on-a-budget">That's how Godzilla: Minus One got an Oscar for Best Visual Effects on a $15 million budget</a>—Shirogumi used ActionVFX stock footage.

<h3>Flexibility Wins</h3>
Need three versions of the same fog pass? Want to test different explosion types in your comp? VFX stock footage gives you the ability to explore options without the overhead of reshoots or re-sims.
It’s not about cutting corners. It’s about working smarter.

Our team films the explosions for you. You just put them into your shot.
<h2>“But Isn’t That Cheating?”</h2>
Only if you believe building everything yourself is a badge of honor.
The truth is, stock assets are one of the most widely used tools in VFX—period. And for good reason. It helps you get better results, faster. And if you do it right, no one will know it was stock to begin with.
You’re not cheating. You’re being efficient.
And as Bryan Haines, Senior Compositor from Crafty Apes once put it:
“ActionVFX gets me home to see my family.”
Hard to argue with that.

<h2>But What About CG vs. Real?</h2>
Let’s clear this up.
Most of our elements are shot practically—real fire, real smoke, real debris. Some others are simulated, rendered, and delivered in a way that gives you more control and consistency.
Both are valid. Both have their place. What matters is that they work in the shot.
<img src="https://a-us.storyblok.com/f/1002378/2048x1080/390d96c3dc/explosion-actionvfx-bts.jpg" alt="">
There’s a whole camp of people who love to say “we don’t use CGI” in their marketing videos, but the truth is… most of them do. They just don’t call it that. (Yes, we're looking at you, Tom Cruise...)
(If you don't know what we're talking about, sorry to burst your bubble, but <a href="https://www.youtube.com/watch?v=7ttG90raCNo&amp;list=PLgdTaHO8FLEve_XFiRBEcOSkRdd-Txjne">almost all the jets in Top Gun: Maverick are CG</a>.)
The best artists care less about how an element was created, and more about what it helps them say in the scene.
<h2>Where Do You Get This Stuff?</h2>
You can shoot it yourself. You can build your own sims. But if you’d rather skip that and get straight to the part where your shot looks good, there’s ActionVFX.
We’ve got:
<ul>
<li>Over 12,000 professional-grade elements</li>
<li>Most elements filmed practically</li>
<li>Everything built for compositors</li>
<li>New collections added every month</li>
</ul>
<img src="https://a-us.storyblok.com/f/1002378/1920x823/240438b0ca/free_vfx_and_pfl.jpg" alt="">
Whether you or your team is working in After Effects, Nuke, Blender, Resolve, or something else, these elements drop in and get the job done.

What is VFX Stock Footage?

You probably didn’t become a VFX artist because you love rotoscoping.
<a href="http://actionvfx.com/blog/introduction-to-rotoscoping-in-nuke">Frame-by-frame roto</a> is one of the most tedious tasks in compositing—especially when dealing with hair, fast motion, or complex shapes. But what if Nuke could learn how to do it for you?
That’s where CopyCat comes in. With the right setup, you can train your own AI model to generate mattes automatically, saving hours of manual work.
<h2>How to Train CopyCat for Rotoscoping</h2>
<a href="https://learn.foundry.com/nuke/content/reference_guide/air_nodes/copycat.html">CopyCat</a> works by analyzing a small set of hand-rotoscoped frames and learning to apply that same matte extraction across an entire shot. The key to getting great results? Training it properly. Here’s how:
<img src="https://a-us.storyblok.com/f/1002378/1920x1080/cb1d88a6da/nuke-node-graph-manual-rotoscope.jpg" alt="">
<h3>1. Roto a Few Key Frames</h3>
Before CopyCat can generate mattes, it needs training data—clean mattes that show it what to learn.
<ul>
<li>Pick 5–10 unique keyframes throughout your shot. Choose frames where the subject’s shape varies the most (e.g., different poses or angles).</li>
<li>Create precise mattes using Nuke’s standard roto tools. The better these keyframes, the better CopyCat will perform.</li>
</ul>
Example: If you’re rotoscoping a person running, choose frames where their legs are in different positions.
If you're still learning the basics of Nuke, here's a great intro to Nuke rotoscoping:
<iframe width="560" height="315" src="https://www.youtube.com/embed/ELg9ncl-0Wo" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen></iframe>
<img src="https://a-us.storyblok.com/f/1002378/1920x1080/b5e590e72a/nuke-copycat-rotoscoping-nodes.jpg" alt="">
<h3>2. Set Up and Train CopyCat</h3>
Once you have your training frames, it’s time to set up the CopyCat node.
<ul>
<li>Add a CopyCat node to your Nuke script.</li>
<li>Connect your original footage to the Input and your hand-made mattes to the Ground Truth input.</li>
</ul>
Next, adjust your training settings:
<ul>
<li>Start with low iterations (~1000-2000) for quick tests.</li>
<li>If the results are good, increase iterations.</li>
</ul>
Click Start Training, and let Nuke process the data. Depending on your settings, training might take a few minutes to an hour.
<img src="https://a-us.storyblok.com/f/1002378/1920x1080/389aa19741/nuke-inference-node-graph.jpg" alt="">
<ol start="3">
<li>Apply It to the Full Shot
Once training is complete and you're happy with the results, it's time to apply it to the full shot.</li>
</ol>
<ul>
<li>Click Create Inference in the CopyCat node. This generates an Inference node, which is used to process the full sequence.</li>
<li>Connect your full clip to the new Inference node.</li>
<li>CopyCat will now auto-generate mattes for every frame, saving you hours of manual roto.</li>
</ul>
If the results need improvement, refine your training frames, retrain the model, and apply again.

If you want to build a career in high-end VFX compositing, learning The Foundry's Nuke is essential.
It’s the software used in major films, TV shows, and commercials because it’s built for high-end compositing. Unlike After Effects, where layers can get messy fast, Nuke’s node-based system gives you total control over every element of your shot.
To help you get started, we just launched a free Intro to Nuke course, led by <a href="https://www.linkedin.com/in/doughogan/">Doug Hogan</a>—a senior compositor with 18+ years of experience in the feature film industry. He’s worked on projects ranging from indie films to major productions, and in this 6-part course, he’ll guide you through the fundamentals of Nuke, breaking down complex concepts into clear, practical lessons.
What this 6-part course covers:
<ul>
<li>Understanding Nuke’s interface and workflow</li>
<li>The four essential nodes that power every composite</li>
<li>Green screen keying, masking, and advanced compositing techniques</li>
<li>3D compositing and integrating VFX elements</li>
<li>Industry best practices for structuring node graphs</li>
</ul>
Whether you're transitioning from After Effects or brand new to compositing, this course will teach you the right way to approach Nuke.
<h2>Chapter 1: Understanding Nuke’s Workflow</h2>
When you first open Nuke, it might feel overwhelming. The interface and workflow are vastly different from layer-based software like After Effects.
In Chapter 1, Doug walks you through:
<ul>
<li>The Nuke interface and how to navigate it</li>
<li>How to set up your first project</li>
<li>Loading and converting image sequences</li>
<li>Why node-based compositing offers more control than layers</li>
</ul>

<h2>CHAPTER 2: The Four Essential Nodes for Every Composite</h2>
You don’t need to memorize hundreds of nodes to work in Nuke—most of your work will rely on just a few.
<ul>
<li>Read – Brings assets into Nuke</li>
<li>Merge – Controls how layers interact</li>
<li>Transform – Moves, scales, and rotates elements</li>
<li>Grade – Adjusts color and exposure for seamless blending</li>
</ul>

Learn Nuke in this free 6-part course by Doug Hogan, starting with the fundamentals and building up to professional techniques.

Master Nuke Compositing: Free Introduction Course to Nuke

The Dune films have some of the most visually stunning effects in modern cinema, so when I saw Dune: Part Two nominated (and winning!) Best Visual Effects at the Oscars, I knew I had to make something inspired by it.
Armed with a few simple materials, a green screen, and some <a href="https://actionvfx.com/products">assets from ActionVFX</a>, I created my own Dune-inspired shot in my at-home studio. Here’s how I did it.
<iframe width="560" height="315" src="https://www.youtube.com/embed/Hw7r4Dwg3TE" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen></iframe>
<h2>Step 1: Building the Filt Plug for the Stillsuit</h2>
If you’ve seen Dune, you’ll recognize the Filt Plug— the small black tube that connects from the back of the head to the nostrils in the stillsuit. You can buy them for cosplay, but I wanted the challenge of making one myself.
So, I took a trip to Lowe’s and found exactly what I needed: flexible tubing and a 90-degree connector. Back at my workspace, I:
<ul>
<li>Cut the tubing a little longer than necessary.</li>
<li>Trimmed the sharp point off the connector.</li>
<li>Heated and molded the tubing to fit my face (without burning myself, thankfully).</li>
<li>Adjusted the fit by bending it over my ear and trimming the excess.</li>
</ul>
With that, the Filt Plug was done! Next, I grabbed my shemagh from my airsoft days, and it was time to set up the shot.
<img src="https://a-us.storyblok.com/f/1002378/1920x1080/d0d5cb2e8c/dune-diy-filt-plug.jpg" alt="">
<h2>Step 2: Lighting and Filming</h2>
Lighting plays a massive role in selling the illusion. To match the Dune aesthetic, I set up:
<ul>
<li>A strong light over my shoulder to mimic the harsh desert sun.</li>
<li>An LED panel with a softbox in front of me for subtle fill lighting.</li>
<li>Tube lights to evenly light the green screen.</li>
<li>A box fan to add a little movement for realism.</li>
</ul>
To create the effect of dried skin from the desert air, I relied on my lack of a skincare routine—finally, a benefit! With everything in place, I recorded multiple takes, eventually choosing the most natural-looking performance.
<img src="https://a-us.storyblok.com/f/1002378/1920x1080/5edb56b313/dune-diy-vfx-bts.jpg" alt="">
<h2>Step 3: Keying and Compositing the Shot in After Effects</h2>
Once filming was done, I moved into After Effects to composite everything together. Here’s how I built the scene:
<ul>
<li>Pre-composing – The footage was shot in 6K, but working at that resolution isn’t practical or fast. I pre-composed it so After Effects would treat it as 2K when applying effects.</li>
<li>Keying the Green Screen – Using the built-in Keylight plugin, I removed the background and adjusted the alpha contrast.</li>
<li>Flipping the Background for Lighting Consistency – Since my highlights were on the left and the background’s were on the right, I flipped the desert plate horizontally to match.</li>
</ul>
<img src="https://a-us.storyblok.com/f/1002378/1920x1080/c6ee29e26e/dune-movie-bts.jpg" alt="">
<h3>Adding the Sandstorm</h3>
To create the iconic dust storms of Arrakis, I had to get creative. By repurposing <a href="https://www.actionvfx.com/collections/blizzard-snow-stock-footage">Blizzard Snow</a> assets from ActionVFX, I got exactly what I was looking for. With a few adjustments:
<ul>
<li>I flipped them horizontally to match the wind direction.</li>
<li>Used Unmult to remove the black background.</li>
<li>Tinted the snow an orange-brown hue.</li>
<li>Staggered multiple layers with different scale, color, and luminance to add depth.</li>
</ul>
To maintain visibility of the dunes, I duplicated the background, brought it above some of the Blizzard Snow layers, masked only the bottom, and feathered it. This helped blend everything seamlessly.
<h3>Creating the Spice Particles</h3>
No Dune-inspired shot is complete without spice floating in the air. I used ActionVFX <a href="https://www.actionvfx.com/collections/dust-particles-stock-footage">Dust Particles</a> and:
<ul>
<li>Tinted them red-orange to match the look of spice.</li>
<li>Set the blending mode to Add for a glowing effect.</li>
<li>Adjusted speed and opacity for a more organic look.</li>
</ul>
<h2>Step 4: Enhancing the Shot with the Blue Eyes Effect</h2>
In the Dune universe, exposure to spice turns a person’s eyes blue. To achieve this, I:
<ul>
<li>Motion-tracked my eyes to keep the effect locked in place.</li>
<li>Used an <a href="https://www.actionvfx.com/collections/eye-textures-stock-footage">eye texture</a> from ActionVFX to enhance the vibrancy.</li>
<li>Created a blue solid layer and set it to Color blending mode.</li>
<li>Masked and feathered the eyes for a natural transition.</li>
</ul>
This process required a lot of manual <a href="https://www.actionvfx.com/blog/how-to-do-motion-tracking-with-mocha-ae-beginner-friendly-after-effects-tutorial">tracking</a>, but the result was worth it!
<h2>Step 5: Final Touches – Noise, Lens Flares, and Camera Shake</h2>
To make the shot feel even more immersive, I added:
<ul>
<li>Organic Dust Motion – Using directional blur and noise textures, I made the foreground Blizzard Snow layers feel more like sand particles, and simulated the chaotic movement of dust particles in the wind.</li>
<li>A Lens Flare – I used an <a href="https://www.actionvfx.com/collections/Icon-anamorphic-lens-flares-stock-footage">Icon: Anamorphic Lens Flare</a> from ActionVFX, tweaking the contrast and hue for a warm, cinematic glow.</li>
<li>Subtle Camera Shake – Added a slight handheld effect for realism.</li>
<li>Final Color Grade – Using DaVinci Resolve, I fine-tuned the colors for a more cohesive desert look.</li>
</ul>
<img src="https://a-us.storyblok.com/f/1002378/1920x1080/d8474aea51/dune-vfx-shot.jpg" alt="">
<h2>The Final Result</h2>
After all these steps, the shot was complete! What started as a small room with a green screen became an intense, cinematic sandstorm straight out of Arrakis.

How I Recreated Dune: Part Two VFX in My At-Home Studio

Armed with a few simple materials, a green screen, and some assets from ActionVFX, I created my own Dune-inspired shot in my at-home studio with After Effects.

If you’re an ActionVFX user working in Adobe After Effects, you might have run into issues with certain assets in the DRAGONcolor2 / REDgamma4 color space. Since After Effects doesn’t natively support this format, getting the most out of these assets requires a few extra steps.
In this guide, we’ll walk you through how to properly interpret, transform, and composite DRAGONcolor2 assets while keeping all the original data intact.
<h2>Why Some Assets Use DRAGONcolor2 / REDgamma4</h2>
Many of our older assets were filmed on RED DSMC2 cameras, which used DRAGONcolor2 / REDgamma4 to retain as much data as possible. While this was a great choice for quality, Adobe After Effects doesn’t play nice with this color space—meaning your assets may look washed out or incorrect when imported. You might notice this on our older pyro collections like Window Fire or Gas Explosions Vol. 1, among a few others.
The good news? There's an easy way to fix this thanks to our friends at RED.
<img src="https://a-us.storyblok.com/f/1002378/900x506/61233150cf/red-camera-bts.jpg" alt="">
<h2>The Fix: Custom LUTs from RED</h2>
To solve this issue, RED developed custom LUTs specifically for ActionVFX users. These LUTs convert different RED gammas into a more usable format, making compositing in After Effects much easier.
🔥 Pro Tip: You can <a href="https://s3.us-east-1.amazonaws.com/uploads.actionvfx.com/public_downloads/REDGammaLUTs_64x_v02.zip">download these LUTs for free here</a>.
Before you get started, if you're not familiar with ACES color management and how it streamlines compositing, you'll need to check out our <a href="https://actionvfx.com/blog/how-to-use-aces-in-after-effects">ACES guide</a> first.
<h2>How to Set Up DRAGONcolor2 / REDgamma4 Assets in After Effects</h2>
Follow these steps to properly set up your assets and maintain full color accuracy.
You can follow step-by-step along with Sam in our tutorial:
<iframe width="560" height="315" src="https://www.youtube.com/embed/q249a3SH320" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen></iframe>
1. Set the Correct Input Color Space
<ul>
<li>Right-click your asset in the Project Window → Interpret Footage &gt; Main</li>
<li>Go to the Color Tab</li>
<li>Under Override Media Color Space, select: Input/RED/Input - RED - Linear - DRAGONcolor2</li>
</ul>
At this point, the colors will still look off—but don’t worry, we’re about to fix that.
2. Apply the RED LUT in Lumetri
<ul>
<li>Add the Lumetri Color effect to your asset</li>
<li>Under Basic Correction, locate the Input LUT option</li>
</ul>
Instead of using the default presets, we need to add one of the custom LUTs:
<ul>
<li>Open File Explorer</li>
<li>For Windows, navigate to: Local Disk &gt; Program Files &gt; Adobe &gt; Adobe After Effects &gt; Support Files &gt; Lumetri &gt; LUTs &gt; Technical</li>
<li>For Mac navigate to: Macintosh HD &gt; Applications &gt; Adobe After Effects &gt; Adobe After Effects.app (right click to “Show Package Contents”) &gt; Lumetri &gt; LUTs &gt; Technical</li>
<li>Drag and drop the RG4_2_LIN_64.cube LUT from the RED LUT pack into this folder</li>
<li>Restart After Effects</li>
<li>Now, in Lumetri’s Input LUT section, select RG4_2_LIN_64</li>
</ul>
Once applied, your footage will now display correctly in <a href="https://actionvfx.com/blog/how-to-use-aces-in-after-effects">ACES</a>, retaining all of its original data for proper compositing. Once the LUT is added to the correct folder, it will always be available in future projects.
<h2>Making This Process Even Faster</h2>
If you’re working with a lot of our DRAGONcolor2 / REDgamma4 assets in the same project, you can save time by applying your initial footage interpretations to multiple files at once.
Use “Remember Interpretation”
<ul>
<li>After setting up one asset, right-click it in the Project Window</li>
<li>Select Interpret Footage &gt; Remember Interpretation</li>
<li>Now, apply this interpretation to multiple assets at once by selecting them, right-clicking, and choosing Apply Interpretation</li>
<li>Add Lumetri once the asset is in your Comp</li>
<li>Select your RG4_2_LIN_64 LUT as your Input LUT</li>
</ul>
Final Thoughts
By following this workflow, you’ll ensure your DRAGONcolor2 / REDgamma4 assets composite seamlessly into your After Effects projects without any color issues.

Have you ever struggled to get VFX elements to blend seamlessly into your scene? The key to pro-level compositing isn’t just <a href="https://www.actionvfx.com/blog/after-effects-quick-tip-how-to-light-your-vfx-elements-using-normal-pass">lighting</a> or effects—it’s understanding color spaces.
In our latest video, Sam breaks down how color spaces impact your composite and why ACES (Academy Color Encoding System) is a game-changer for standardizing colors across different assets.
<iframe width="560" height="315" src="https://www.youtube.com/embed/pYzN_g-1N_w" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen></iframe>
<h2>Why Color Spaces Matter</h2>
Cameras, monitors, and software all interpret colors differently. If you’re using footage from multiple sources, mismatched color spaces can cause assets to look completely out of place. That’s where ACES comes in—it acts as a universal translator, ensuring all your elements exist in a consistent color space.
To understand this a little deeper, you can check out our blog on <a href="https://www.actionvfx.com/blog/the-difference-between-linear-and-logarithmic-color-space-and-why-you-should-care">linear and logarithmic color spaces</a>.
<h2>How ACES Works in Compositing</h2>
ACES uses input and output transforms to standardize footage:
<ul>
<li>Input Transform – Converts your footage’s original color space into ACES.</li>
<li>Output Transform – Converts ACES footage back into the final deliverable color space.</li>
</ul>
The best part? All major compositing software, including After Effects and Nuke, have the ACES workflow system built-in. You can preview your composite in your final delivery format while still working with high-quality data.
🔥 Pro Tip: After Effects doesn’t have a built-in transform for DRAGONcolor2 / REDgamma4 assets. <a href="https://actionvfx.com/blog/fix-color-issues-in-after-effects-free-luts">Check out our other blog to learn how to set it up properly.</a>
<h2>Setting Up ACES in After Effects</h2>
1. Change Project Settings
<ul>
<li>Go to File &gt; Project Settings &gt; Color and switch to OCIO Color Managed.</li>
</ul>
2. Set the Footage Input Color Space
<ul>
<li>Right-click footage → Interpret Footage &gt; Main &gt; Color tab</li>
<li>Select the correct input transform (e.g., REDWideGamutRGB / REDLog3G10).</li>
</ul>
3. Blend Different Color Spaces Seamlessly
<ul>
<li>When working with multiple assets (e.g., Rec.709, DRAGONcolor2), use the correct transforms to unify their look.</li>
</ul>
4. Render in the Original Color Space
<ul>
<li>When exporting, set the Output Color Space to match your footage for easier grading.</li>
</ul>
<h2>Why ActionVFX Assets Are Built for ACES</h2>
At ActionVFX, we provide assets in multiple color spaces—Rec.709, Linear, ACEScg, DRAGONcolor2, and more—so you can get the best data for your composite. We even list the color space on each product page, making it easy to match your workflow.
🔥 Pro Tip: Always check an asset’s color space before starting your composite. Otherwise, Sam might show up at your house to fix your input transform himself. (You’ve been warned.)

How to Use ACES in After Effects (& Why Color Spaces Matter)

The <a href="https://www.youtube.com/watch?v=a0JMSj5xdFk">Captain America: Brave New World</a> trailer showed off some intense action, including Red Hulk making a fiery entrance. In this tutorial, our very own Wyatt turned himself into Red Hulk in After Effects.
Learn how to make Hulk's glowing eyes, red skin, expanding hands, and ground-shattering impact.
The best part? You can do it all for just five credits or less using the ActionVFX library.
<iframe width="560" height="315" src="https://www.youtube.com/embed/3SdkmysscnI" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen></iframe>
Here's a quick rundown:
<h3>Step 1: Turning Your Skin Red</h3>
The first thing we need to do is change skin color. Using After Effects, you can create this effect by:
<ul>
<li>Duplicating your base footage</li>
<li>Using the <a href="https://www.actionvfx.com/blog/when-should-i-use-after-effects-roto-brush-tool">Roto Brush Tool</a> to isolate skin areas</li>
<li>Applying a Tint effect and mapping black/white values to a deep red</li>
<li>Adjusting brightness, contrast, and blending modes to make it look natural</li>
</ul>
By keyframing the effect, you can make the transformation happen gradually, just like in the movies.
<h3>Step 2: Adding Glowing Red Eyes</h3>
No Hulk transformation is complete without those intense glowing eyes. Here’s how to do it:
<ul>
<li>Mask out your eyes so they stay unaffected by the red skin tone</li>
<li>Import an ActionVFX <a href="https://www.actionvfx.com/collections/eye-textures-stock-footage">iris texture</a> (included in the Essentials Catalog)</li>
<li>Scale and position it over the eye and set the blend mode to Overlay</li>
<li>Use <a href="https://www.actionvfx.com/blog/how-to-do-motion-tracking-with-mocha-ae-beginner-friendly-after-effects-tutorial">Mocha tracking</a> to lock it in place</li>
<li>Add a glow effect to make them pop</li>
</ul>
This technique makes the eyes look alive and dynamic, rather than just color overlays.
<h3>Step 3: Creating a Ground-Smashing Impact</h3>
This is where things get destructive. When Red Hulk smashes the ground, you'll need:
<ul>
<li>Ground cracks</li>
<li>Burning steel wool effects to simulate fire spreading (<a href="https://actionvfx.com/redeem">redeem for free</a> with code &quot;HULK&quot;)</li>
<li>Steam and <a href="https://www.actionvfx.com/collections/free-dust-wave-stock-footage">dust waves</a> help sell the impact</li>
</ul>
To make it work seamlessly:
<ul>
<li>Track the ground plane so the cracks match the perspective</li>
<li>Use <a href="https://www.actionvfx.com/blog/how-blending-modes-work-in-after-effects">blending modes</a> like Overlay or Screen to integrate the effects</li>
<li>Add motion blur to enhance realism</li>
<li>Keyframe opacity changes so the fire and smoke evolve naturally over time</li>
</ul>
<h3>Bringing It All Together</h3>
With these elements in place, you can refine the scene by:
<ul>
<li>Layering <a href="https://www.actionvfx.com/collections/atmosphere/category">atmospheric effects</a> like embers, sparks, and dust</li>
<li>Adding subtle <a href="https://www.actionvfx.com/collections/free-camera-shake-presets-stock-footage">camera shake</a> for extra impact</li>
<li>Fine-tuning depth of field to make everything feel cinematic</li>
</ul>

When it comes to sourcing top-quality VFX assets, FX Elements and ActionVFX often appear in the same conversation. Both offer incredible tools for VFX artists, but which one is the better choice for your project? Let’s dive into the key differences, debunk some myths, and help you determine which option works best for your needs.
<h2>FX Elements: A Good Option for Individual Clip Purchases</h2>
<img src="https://a-us.storyblok.com/f/1002378/1849x669/298594e8ab/fx-elements-stock-footage.png" alt="">
FX Elements is a great solution for filmmakers who need one or two specific assets, especially for one-off clip purchases. Though their selection is much smaller than ActionVFX—ActionVFX adds an average of six collections per month to its <a href="https://actionvfx.com/products">growing library</a>—the assets available through FX Elements are high quality. With individual clips starting at $9 (just $0.90 less than ActionVFX), this platform caters to those with minimal requirements or tight budgets.
However, if you need more than one or two assets, ActionVFX is the better choice. Here’s why:
<ul>
<li>FX Elements has daily download limits. Unlike ActionVFX, FX Elements’ subscriptions restrict you to 15 downloads per day, which can be a bottleneck for larger projects.</li>
<li>FX Elements has a smaller library. FX Elements offers fewer options overall, making it harder to find exactly what you need. The ActionVFX library, containing around 12,000 assets, is <a href="https://actionvfx.com/testimonials">regularly praised</a> for its wide selection of elements.</li>
<li>Greater flexibility with ActionVFX. The ActionVFX <a href="https://www.actionvfx.com/blog/the-future-of-actionvfx">credits-based model</a> lets you choose only the assets you need, whenever you need them, without restrictions like download limits when using credits. Subscribers also get assets in the <a href="https://www.actionvfx.com/products/essentials-catalog">Essentials Catalog</a> for free (up to 20 downloads per day).</li>
<li>All file types included with ActionVFX. With ActionVFX, you get access to all file and resolution types at no extra cost, unlike FX Elements, which charges more for additional file types.</li>
</ul>
For projects requiring a broader selection of assets or the flexibility to download without daily limits, ActionVFX stands out as the superior choice, especially with an average of six new collections released per month.
Here's a cool testimonial video from Shirogumi, the team that produced Oscar®-winning Godzilla Minus One:

<h2>Myths About the ActionVFX Subscription</h2>
There’s some <a href="https://www.filmmaker.tools/non-subscription-alternatives-to-actionvfx">misinformation floating around</a> about ActionVFX’s subscription model, so let’s clear things up:
Myth 1: &quot;You’re forced to pay for assets you might not use.&quot;
Truth: The ActionVFX subscription gives you credits to spend on any asset in the library, putting you in control. You pay for credits, then spend the credits however you’d like. Other “free for subscribers” offerings do not add to the cost of the subscription.
Myth 2: &quot;There’s less flexibility compared to pay-per-clip options.&quot;
Truth: This is true, only if you only need one asset total. With ActionVFX, you get what you need, when you need it. Credits make it easy to tailor your downloads to your current projects while saving significantly compared to individual purchases. Additionally, you can scale your plan by purchasing additional credits if you ever run out.
Myth 3: &quot;ActionVFX limits downloads to a few per month.&quot;
Truth: While FX Elements has a 15-asset daily download limit, ActionVFX allows unlimited downloads when using credits. If you run out of credits, you can purchase more without needing to upgrade your plan. For Essentials Catalog assets, subscribers can download up to 20 assets per day.
Myth 4: &quot;Assets are hidden behind a paywall after you subscribe depending on your tier.&quot;
Truth: Once you subscribe, you can spend your credits on <a href="https://actionvfx.com/products">any asset</a> in the ActionVFX library, including assets created by third-party contributor. No tiered access or restrictions.
Myth 5: &quot;ActionVFX increased their prices.&quot;
Truth: The new ActionVFX subscription is a significant price cut for the vast majority of artists. While it’s not as cheap as our old Legacy subscription model, which we discontinued in 2023 due to its unsustainability for our business, most users save about 50% compared to our individual asset purchasing model, which we have used since our launch in 2016.
For example, individual 4k assets used to cost $39. Now, by spending credits, individual assets cost an average of $11.95, and as low as $9.90. Plus, when you download an asset, you get all available resolution types. <a href="https://www.actionvfx.com/blog/the-future-of-actionvfx">Here’s a breakdown on how ActionVFX credits work.</a>
Myth 6: &quot;ActionVFX is only for studios.&quot;
Truth: While many of our clients are studios, ActionVFX is a also great option for freelancers. Unlike most subscription models, we designed ours so that you keep what you download, even if you cancel. This allows all users to benefit from our library, even those who can only afford a one-time purchase.

<h2>Why the ActionVFX Subscription Stands Out</h2>
<h3>ActionVFX Has More Options, Higher Value</h3>
The ActionVFX subscription includes all file types at no extra cost. This contrasts with FX Elements, which charges more for higher-quality files.
All ActionVFX subscribers also get free access to 1570 assets in the <a href="https://www.actionvfx.com/products/essentials-catalog">Essentials Catalog</a>. Subscribers can download up to 20 of these assets per day without spending any credits.
<h3>ActionVFX Offers Incredible Savings</h3>
One of the biggest advantages of ActionVFX credit plans is how much more affordable they are compared to individual purchasing. For just $59 per month, you gain access to assets that used to cost up to $195 when purchased individually. That means that as long as you plan to download more than one asset, the credits-based subscription is far cheaper than the old individual asset purchasing model.
The math speaks for itself: subscribing saves you money and gives you more creative freedom.
<h2>With ActionVFX, Cancel Anytime and Keep Your Assets</h2>
Unlike traditional subscriptions, with ActionVFX credit plans, you keep downloaded assets even if you cancel. This lets independent creators benefit from the savings a credit model provides without needing to maintain a monthly subscription during slow months.
<h2>Is ActionVFX a Good Option for Independent Artists?</h2>
Absolutely. ActionVFX understands that not every filmmaker works with a blockbuster budget. We also understand that your needs fluctuate throughout the year. Here’s how we solved that:
<ul>
<li>Credits roll over for 12 months, meaning you can save up credits during slow periods to spend them as you need.</li>
<li>Don’t benefit from month-over-month credit accumulation? Subscribe for one month, spend your credits, then cancel. As long as you spend more than one credit, you’ll save $20 to $136 compared to our old individual purchasing model.</li>
</ul>
<img src="https://a-us.storyblok.com/f/1002378/1879x657/e6b2a2d3b8/actionvfx-homepage.jpg" alt="">
As an independent artist, you can access the same high-quality assets used in blockbusters like Godzilla Minus One, Stranger Things, Spider-Man: Far From Home, Avengers: Endgame, and more—all without breaking the bank.
The responses to the OP in <a href="https://www.reddit.com/r/vfx/comments/1eoalu7/action_vfx_worth_it/">this thread</a> are great examples of how independent VFX artists use our assets. Read the comments!
<h2>FX Elements or ActionVFX: Which One Should I Use?</h2>
Both FX Elements and ActionVFX cater to different needs. If you require individual purchasing of a few assets, FX Elements is a great choice. But for anyone needing long-term value, a wide selection of assets, and consistent month-over-month project budgeting, <a href="https://actionvfx.com/testimonials">the ActionVFX subscription is a clear winner</a>.
With unparalleled savings, unmatched flexibility, and a library packed with professional-grade assets, ActionVFX continues to set the gold standard in the industry. So, is ActionVFX worth it? Absolutely. Give it a try and see the difference for yourself.

In this article we give an overview of how to use CG scenes in your projects, then highlight a few of our favorite free scenes of 2024 that you can download.
<h2>Understanding CG scenes</h2>
CG scenes are digitally created environments that serve as settings for <a href="https://actionvfx.com/3d">3D models</a>. They allow 3D artists to control lighting, staging, and composition to create realistic or imaginative settings.
<h2>What are CG scenes?</h2>
A CG scene is a collection of various elements, including 3D models, textures, lighting setups, and camera angles, arranged to create a cohesive and visually appealing environment. These scenes are created using <a href="https://www.actionvfx.com/blog/a-comprehensive-guide-to-the-best-3d-vfx-software">3D software</a> such as Autodesk Maya, Blender, or Cinema 4D. Artists have the freedom to manipulate every aspect of the scene to achieve their desired visual outcome.
CG scenes come in various types, each serving specific purposes for artists. Architectural scenes are used for visualizing buildings and interiors, helping artists showcase architectural designs with different materials and lighting. Nature and landscape scenes offer depictions of the natural world, from forests to beaches, allowing artists to create immersive environments that capture the beauty of nature. Character and creature scenes focus on character modeling and animation, featuring diverse figures in various poses for artists to practice rigging and animating.

Understanding alpha channels is essential to compositing in popular software like After Effects, Nuke, and DaVinci Resolve Fusion. <a href="https://www.actionvfx.com/blog/what-is-an-alpha-channel">Alpha channels</a> play a crucial role in determining the transparency and blending of layers, allowing you to seamlessly integrate your footage.
In this comprehensive guide, we'll dive deep into the two main types of alpha channels—premultiplied and straight—and explore how to correctly interpret and work with them in After Effects, Nuke, and DaVinci Resolve Fusion.
<h2>What are Alpha Channels?</h2>
Before we delve into the specifics of premultiplied and straight alpha, let's take a step back and understand what alpha channels are. In simple terms, an alpha channel is an additional channel in an image or video that stores transparency information. It determines which parts of the image are opaque, transparent, or semi-transparent. Alpha channels are essential for compositing footage, <a href="https://www.actionvfx.com/blog/a-beginner-s-guide-to-alpha-luma-mattes-after-effects-tutorial">creating masks</a>, and achieving various transparency effects.
Think of an alpha channel as a grayscale image that sits alongside the RGB color channels. In this grayscale image, white represents fully opaque areas, black represents fully transparent areas, and shades of gray represent varying levels of transparency. By using alpha channels, you can create complex compositions where elements seamlessly blend with each other and the background.

<h2>Premultiplied vs. Straight Alpha Channels</h2>
Now that we have a basic understanding of alpha channels, let's explore the two main types: premultiplied alpha and straight alpha.
<h3>Premultiplied Alpha (or &quot;Matted&quot;)</h3>
Premultiplied alpha, also known as &quot;matted&quot; alpha, is a type of alpha channel where the RGB color channels are multiplied by the alpha channel values. In other words, the color information is &quot;baked&quot; into the transparency. This means that the edges of the image appear smooth and anti-aliased against the background, resulting in a more natural blending.
Premultiplied alpha is commonly used in video codecs and is the default setting in most all software. When you import footage with premultiplied alpha, the software automatically interprets it correctly, ensuring that the transparency and color information are handled properly during compositing.
<h3>Straight Alpha (or &quot;Unmatted&quot;)</h3>
Straight alpha, also referred to as &quot;unmatted&quot; alpha, is a type of alpha channel where the RGB color channels and the alpha channel are stored separately. In this case, the color information is not pre-multiplied with the transparency values. As a result, the edges of the image may appear harsh and jagged against the background. If the edges of the alpha ever look messy upon import, the image is likely using straight alpha.
Straight alpha is often used in graphics and still images, such as those created in Photoshop or Illustrator. When working with straight alpha footage in After Effects, Nuke, or DaVinci Resolve Fusion, it's important to correctly interpret the alpha channel to ensure proper compositing and transparency.

<h2>Interpreting Alpha Channels in After Effects, Nuke, and DaVinci Resolve Fusion</h2>
Now that you understand the difference between premultiplied and straight alpha, let's walk through the process of interpreting alpha channels correctly in each software.
<h3>Alpha Channels in After Effects</h3>
<ol>
<li>Select the footage in the Project panel.</li>
<li>Right-click on the footage and choose &quot;Interpret Footage&quot; &gt; &quot;Main...&quot;</li>
<li>In the Interpret Footage dialog box, locate the &quot;Alpha&quot; section.</li>
<li>Choose the appropriate alpha channel interpretation based on your footage:</li>
</ol>
<ul>
<li>For premultiplied alpha footage, select &quot;Premultiplied - Matted With Color:&quot;</li>
<li>For straight alpha footage, select &quot;Straight - Unmatted&quot;</li>
</ul>
<ol start="5">
<li>Click &quot;OK&quot; to apply the changes.</li>
<li>Right-click the footage you changed the settings for and choose “Reload Footage”.
<img src="https://a-us.storyblok.com/f/1002378/928x346/a6b3c51b36/alpha_channels_after_effects.jpg" alt=""></li>
</ol>
<h3>Alpha Channels in Nuke</h3>
To go from straight alpha to pre-multiplied alpha:
<ol>
<li>Add a <a href="https://www.actionvfx.com/blog/6-common-but-not-obvious-nodes-for-nuke-beginners">“Premult” node</a> and connect the input to your footage.
<img src="https://a-us.storyblok.com/f/1002378/930x277/c72b9826c8/premult_node_nuke.jpg" alt=""></li>
</ol>
To go from pre-multiplied alpha to straight alpha:
<ol>
<li>Add an “Unpremult” node and connect the input to your footage.
<img src="https://a-us.storyblok.com/f/1002378/933x280/d0715e7e64/unpremult_node_nuke.jpg" alt=""></li>
</ol>
Unpremultiplying an image is useful when doing color corrections on footage with an alpha channel as it ensures the semi-transparent pixels receive the same edits as the fully opaque pixels. After your color corrections, you would then Premult the image before Merging it over top of the background.
<h3>Alpha Channels in DaVinci Resolve Fusion</h3>
<ol>
<li>Right-click the footage in the Media Pool.</li>
<li>Hover over “Change Alpha Mode.”</li>
<li>Choose the appropriate alpha channel interpretation:</li>
</ol>
<ul>
<li>For premultiplied alpha footage, select &quot;Premultiplied.&quot;</li>
<li>For straight alpha footage, select &quot;Straight.&quot;</li>
</ul>
<ol start="4">
<li>The changes will be applied automatically.
<img src="https://a-us.storyblok.com/f/1002378/936x545/9ffdea56d3/change_alpha-mode_davinci_resolve_fusion.jpg" alt=""></li>
</ol>
By selecting the correct alpha channel interpretation in each software, you ensure that the transparency information is treated accurately, resulting in proper compositing and blending with other layers.
<h2>Common Alpha Issues and Solutions</h2>
When working with alpha channels, you may encounter some common issues. Let's explore a few of them and their solutions:
1. Dark or Bright Edges: If the edges of your footage or VFX asset are darker or brighter than they should be, it's likely that the alpha channel interpretation is incorrect. To fix this, change the alpha channel interpretation in the respective software settings as described earlier.
2. Edge Fringing: Edge fringing, or a thin halo around the edges of composited footage, can occur due to a mismatch in the alpha channel.
3. Software Differences: There are some inconsistencies in the way some software handles alpha channels. Even the major players such as After Effects and Nuke handle pre-multiplied alpha channels slightly differently. If you notice that you aren’t getting the same result when going from one software to another, try using straight alpha channels for your renders. Almost all software handles straight alpha channels the same way. You may have noticed that some <a href="https://actionvfx.com/products">ActionVFX collections</a> are delivered with a straight alpha channel for this reason. Remember to check your footage's alpha channel interpretation, experiment with blending modes, and leverage the unique tools each software offers to refine your composites.
Understanding alpha channels is a <a href="https://www.actionvfx.com/blog/a-free-beginner-s-guide-to-learning-vfx-from-home">fundamental skill</a> for VFX compositing, regardless of the software you use. By mastering the concepts of premultiplied and straight alpha, and knowing how to correctly interpret them in After Effects, Nuke, and DaVinci Resolve Fusion, you'll be well-equipped to create stunning VFX.
