Prefer webp over gif

GitHub supports videos inside readmes:

From my understanding gifs are huge in size, and have often been subtly replaced by other formats by social media networks because of this. I'm not sure if github does the same edge optimisations as other sites do, or if terminal usage with limited colours and frames are the better for gifs than other formats.

Update, seems videos in readmes don't autoplay.

Update 2, seems animated png died out (didn't animate on ios safari), however animated webp seems to have won:

Update 3, animated webp support is already supported by github as it just delegates images to browser support:

Update 4, seems webp support needs to be added to vhs first:
