5 Ways To Repair Problematic Video With After Effects

From unwanted flicker to unstable footage, we’ll show you how to fix some of the most common video problems!

Chances are you’ve probably had to deal with less-than-perfect footage at some point in your career. If you need some help on how to denoise a video (or remove noise from grainy footage), we’ve got you covered in this previous article.

Today, we’re going to look at several other common issues you may encounter when working with footage, as well as how to resolve the problems with After Effects. Let’s get started!

1. How to Stabilize Shaky Footage

It’s no secret that dealing with hand-held footage can be a challenge, especially when you’re the one responsible for the compositing and visual effects work. One way to get around this is to shoot a VFX shot locked-down on a tripod, then add camera shake in post. If you didn’t have that luxury, have no fear! Before you start motion tracking, give the Warp Stabilizer VFX effect in After Effects a shot. Simply search for “Warp Stabilizer VFX” in the Effects Panel, and drop it onto your clip.

Smoothing out the camera movements can help when it comes time to track your footage, and it can also give you more control of the overall style of the shot, as well. The video below covers how to use this technique, as well as a couple others we’re going to look at, so take a minute to check it out!

2. How to Remove Blur from Shaky Footage

If you’ve got a shaky camera to contend with, you’ve more than likely got a significant amount of motion blur as well. Simply stabilizing this footage is great, but if you don’t apply another effect, your footage may look like a poor camera desperately searching for an auto-focus point.

The video above also describes a fantastic way to reduce the blur in an unstable video: the Camera-Shake Deblur effect. Camera-Shake Deblur looks at blurry frames that may be adjacent to your playhead, and blends them together with the clip’s sharper frames to help the footage remain in focus for the duration of your clip. For better results, change the “Deblur Method” in the effect from Standard to High Quality.

As mentioned in the video, another tip is to duplicate the effect on your layer for improved deblurring.

3. How to Fix Overexposed and Underexposed Shots

Lumetri Color is a great option for quickly restoring lost detail from an overexposed or underexposed shot. Apply Lumetri Color to your effect, then head to Window>Lumetri Scopes.

Of course, each shot is unique in the adjustments that may need to be made, but the video below shows how you can apply several basic adjustments in Lumetri to repair your footage. It also provides a bit of theory behind how to use various scopes in the Lumetri Scopes window.

4. How to Fix Color Banding in After Effects

You may have an awesome scene with dramatic lighting, or a shot that includes ambient fire or candle lights, only to realize that lighting is emitting an ugly gradient banding across surfaces in the background when it’s imported into After Effects.

Simply changing your comp’s bit depth can help tremendously, and the video below shows you how to do it! You can also add a minor amount of noise to eliminate the banding issue, similar to dithering a .GIF in Photoshop.

5. How to Remove Flicker From Video Footage

It can be incredibly challenging to shoot in a room with fluorescent lighting or computer monitors, because if your shutter speed isn’t set appropriately you can encounter distracting flicker. You can also run into flicker when shooting at a high frame rate for slow-motion capture.

Fortunately, the fix for video flicker is an astonishingly simple one. What’s great about this technique is that it can remove flicker not only in After Effects, but also in Premiere Pro, Final Cut X, HitFilm, and Media Composer. Basically in any video editing software where you can stack two clips, add opacity, and offset the top clip, you'll be able to try this technique out.
We hope you found these tips helpful for fixing common video issues!
