In this quick tutorial, we’ll learn how to do frame by frame painting over video footage on alpha in After Effects. This can be a great way to add some extra detail to your video projects, and it’s a pretty simple technique to learn.
To start, we need some video footage with an alpha channel. This could be footage of a green screen or whiteboard, or it could simply be a video with a lot of contrast. For our example, we’ll be using footage of a whiteboard.
Once you have your footage, create a new composition and drag your footage into it. Then, create a new solid layer and set its mode to “Alpha Add.” This will allow us to see the whiteboard through the solid layer.
Next, use a brush tool to paint over the areas you want to be transparent. You can use any color you want, but we recommend using a bright color so it’s easy to see what you’re doing.
Once you’re finished painting, go to the “Composition” menu and select “Pre-compose.” This will create a new composition with just your painting layer.
Finally, go to the “Effects” menu and select “Change Color.” This will allow you to change the color of your painting. We recommend using a color that’s similar to the background so it’s not too distracting.
And that’s all there is to it! This is a quick and easy way to add some extra detail to your video projects.
