Part 1: Why is My After Effects Not Transparent?

By default, video files contain RGB, which means Red, Green, and Blue. These are the colors in videos, and when you export files in After Effects, RGB is selected by default. The problem with RGB is that it does not have transparency information. Thus, this is the reason that After Effects videos are not transparent.

Fortunately, there is an RGB+Alpha option in After Effects that allows you to export transparent content in the videos. You need to select this option while exporting the video. 

We will explain the complete steps in the upcoming parts of this article.

Part 2: How to Remove Background without Green Screen in After Effects

A green screen makes background removal easier, but it is not possible to have it in every situation.

Step 1: Open After Effects and Create a New Project. Go to the File menu and import the video.

After importing the video, check its resolution and frame rate. Create a New Composition having the same settings.
