Is H264 a possible encoder for the .avi file extension?

I noticed that this was an available option in a video suite that I owned, but I did not notice it in this app. I was wondering if it could be possible to add this extension if it is still compatible.

AVI is so old it will most likely cause problems with anything TVAI is meant to do. The most well-rounded and well-thought-out video container is mkv. mp4 is okay for most things, but not as flexible as MVK.

I thought about that extension because I also saw it as an option for the FFV1 encoder as well as the QuickTime encoder options.
