Lol, I just realized I had sent this to the old Cinelerra list...oops! Maybe this has been covered here or on the forum but on a recent project with some old concert footage I wanted to add some film grain but the 'Aging TV' built-in effect is kind of too much and it also drives the encoder bits wild and make huge file sizes so I did a bit of googling on the ffmpeg noise filters and I found something that works pretty well so I thought I'd share.. https://bandshed.net/images/screenshots/shot-2026-03-21_14-37-53.jpg So going from the picture the main thing is using only the luma color "c0" channel because grain is not comprised of colors from all channels. And in the c0_flags field I used 't+u' to make the grain temporal and change with the frames more realistically. Anyway to be honest I haven't messed in-depth with very many ffmpeg filters so I was very happy to find a good grain option in Cin.. Best, Glen --
