Yes, I’ve seen a video file that changes resolution mid-video, but it’s more of a party trick since not all players handled it well
Specifically, I saw a group chat program rendered it “correctly” (Discord? I don’t remember), so the embedded video would re-flow the rendered chatroom while playing
In my experience, LLMs aren’t really that good at summarizing
It’s more like they can “rewrite more concisely” which is a bit different
