@TomaszW spent long time on those presets including 8mm films.
you might want to give his presets a shot. I personally found on my 8mm films the 4k and 8k presets worked the best for me. give them all a shot.
you can test them all for yourself and preview them on TVAI and if you wish you could also use a compare tool to check the results to see for yourself if you notice any difference between the two (that would save you tons of time). or just playback the 2s / 5s preview you generate from both one right after the other to see if you spot any difference in quality.
