If the target is a GitHub readme, then you can embed a video directly. eg https://github.com/paulirish/git-recent#readme
That said, OP's SVG trick may be a smarter choice if the content is a terminal capture.

When I've personally animated SVGs for use in RevealJS presentations, I tend to use CSS animations that I could control with JS if I wanted.
The idea of committing a video to your repository for a PR seems silly. Every PR adds a new video to the codebase? Do you make a PR to prune them every once in a while?
Git commits only differences with the precedent commit, not the entire repository. Therefore the video is only committed once as long as that video doesn’t change.

edit: sigh.... Works in Firefox and Chrome. Has issues in Safari - I'm sure I could futs with it more and get it to work everywhere but still, sadness
I think it's best for embedding a motion demo of a feature your software provides, no more than 5 seconds. Even then, a video option may be useful to some people.
