Oh interesting, i guess the only downside is that you cant pause or scrub if you really needed to but thats probably a very tiny usecase if at all (maybe for the refinery/chem plant to see the i/o)
Too bad about the size, seems avif is supposed to be better for compression, but all i see is images, so maybe not as great for animations.

Looks like AVIF maybe the future though?

If we can get more compressed images without perceptible loss of quality, then maybe converting all to avif would be good
Backwards compatibility can be candled with the picture tag

I'll check this out on my comp to make sure i can see the new files ok

I could add webP animations as well via a picture tag. The WebP files were much larger. I also converted these via FFMPEG which took a surprisingly long time on my poor MacBook air M1. I COULD NOT get the video files to play on chrome/edge only firefox for some reason. Even though they were muted they refused to play.

It also looks like iOS safari doesn't support AVIF animations so I can include WebP fallback.
