Interesting - say video @ 60fps, encode 1 QR code per frame, would be highly resistant against transcoding errors, very easy to extract information from again given the standard format.
Wouldn't be terribly efficient though. Wikipedia says max bytes per code is 2953 per QR code [1]. So 2953Bps * 60fps = 177KBps data encoding. I guess that's what you get for encoding it in a visual (human readable) format instead of a datastream directly.

- amino 11y agoyou have sound too. Must be an audio equivalent that would have a similar level of durability to a qr code. I dont know if youtube ever drops frames during compression. Perhaps using there 4k support would help get a bit more data
