Once an original video is cryptographically signed, could future uploads be automatically verified based on pixels plus audio? Could allow for commentary to clip the original.
Might need some kind of minimum length restriction to prevent deceptive editing which simply (but carefully) scrambles original footage.
not really… signing is only possible on exact copies (like byte exact; not even “the same image” but the same image, formatted the same, without being resized, etc)… there are things called perceptual hashes, and ways of checking if images are similar, but cryptography wouldn’t really help there
