Part 1: Why is video not transparent in After Effects?

There could be several reasons why a video is not transparent in After Effects.

Reason 1: Not properly setting the alpha channel when exporting the video.

Reason 2: The video format does not support transparency. For example, the AVI format does not support transparency unless it is set to RLE or Uncompressed.

Reason 3: some media players like VLC or QuickTime do not show transparency, so it's important to check the video in a program that supports alpha channels.

To ensure transparency when exporting a video in After Effects, make sure to select "RGB + Alpha" under the "Channels" option in the Output Module1. If the video format does not support transparency, try converting it to a format that does, such as QuickTime with the Animation codec2.

In summary, the lack of transparency in After Effects videos could be due to improper export settings or the video format not supporting transparency. Checking the alpha channel and using a compatible video format can help ensure transparency in the video.
