It mentions that it supports not only sequences but inter-frame prediction (so P- and possibly B- frames I assume), which is sort of surprising to me but of course makes sense especially given Apple's "image burst" usage. I'm also suprised to learn that WebP apparently supports P-frames in its animations.
What's really different between this and the existing usages of the MP4 container for images, though? Is it just the packaging as an "image" format, or specification of more image-y metadata?
