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



IMO it’s time for a reckoning of what’s systematic/automated vs what’s not.
For example, “no expectation of privacy in public” meant you should be okay with appearing in someone else’s (manual) photo while out in public. However, I don’t think that should extend to persistent systematic surveillance, e.g. suppose every Tesla’s camera captures were combined with person recognition systems and tracking.
Just because something is theoretically okay at a small scale doesn’t mean the same applies at large scales.
Another example: Society funds public roads via government taxes for personal use and for regulated commercial use. Uber systematically consumes public road space under the guise of personal use vehicles, for commercial use.
