Ask HN: can this be done?

If film grains are randomly or chaotically distributed, and fractal over enough orders of magnitude, grain might not be error but a medium which interprets and conveys information differently, with unique advantages. But now I'm afraid I sound like an audiophile who buys wooden amp knobs for performance. TeMPOraL on Nov 14, 2022 [–] You've stumbled on an actual, practical use case: encoding watermarks in the grain. I can imagine a watermark hidden in the grain, spread over long enough time (say couple seconds to a minute), so it can survive reencoding with heavy compression and containing enough bits to identify the source of the video on a per-copy/per-user basis.
