WebM or WebP for GIF Replacements?

Question

There are benefits to either approach, but using an animated webp image has the benefit of using the same workflow, semantics and markup as a gif (aside from accessibility concerns).A webm video requires more changes to templates and partials and redoing a lot of work, but is [apparently much faster](https://corydowdy.com/blog/apng-vs-webp-vs-gif).I've read that the underlying tech for these is the same thing, so if I wanted to do a replacement gifs, which one should I choose?

If you are going to do the work I would switch to a proper video format. If you are planning a bit into the future this is probably AV1 with h264 fallback. However it is pretty easy to add or remove formats from the list.I get that you need to change to but that seems like a reasonable thing to do when you are serving video. In exchange you get better mutli-format negotiation, access to controls and seeking if desired, smarter incremental loading...
