Film nerds will talk about grain being necessary for detail on low quality film, but if you actually zoom in on most super grainy sources, it usually ends up being bad compression. You can tell because the dots are perfect squares, film grain isn’t.
The filmcels are lying to us.
Granny video makes compression basically not work at all. Or very poorly. I remember ripping a blueray of a movie that was very grainy for artistic reasons, running it through handbrake and it coming out larger that it was when I put it in. The clearer the video the easier it is to compress and make good guesses about what was supposed to be there.
You have to actually know what you’re doing in ffmpeg to get “grainy” sources to look decent.
Fake grain looks like ass. If you want grain shoot on real high ISO film and embrace the grain.
