Version 7: Brand new custom grain DCTL Removed mid-tone softening Grain is now after the FLC I abandoned the grain OFX plugins and wrote my own grain generator DCTL based on a random number generator with some sliders to modify the channel gains and saturation etc, and I tuned it to match some Vision3 samples from a friend. It's mostly blue and a little green with no red. Putting it before the FLC screwed up the colours and I couldn't work out what to put in to get the right result out, so I just moved the grain to after the FLC. This might mean it isn't right across the luma range, so happy to hear feedback on that. I also added a resolution chart at the back as I was using it to test some things and decided to keep it in there. It's an 8K source file, so was nice and sharp going into the grade... Fun! -

This is correct. Depending on the emulsion, grain is also not sized uniformly. And since you posted the Take 2 Films' tour of Kodak, it's also worth pointing out their latest film is comparing a couple of different film stocks and methods of processing them. This aligns with something that I frequently say - "film look" is meaningless as a phrase, given that different films have different characteristics - and depending on processing, can take on even more other characteristics. -
Did the grain in previous versions also look like this, or have I done something that pushes it in the wrong direction perhaps? Version 4: Version 6: I got feedback that Vision3 tends to only have grain that is in the yellow/blue direction, unlike mine that contains a lot of grain on the red channel (despite there being a slider for this and me turning it down), so I'm going to rebuild the grain engine again to give me some better control over this. I've heard that grain "crawls" and even seen controls for this in the OFX, but I have no idea what this means. Do you know? I might have to read about this. I would assume (perhaps naively) that there would be no relationship between the grain on each frame, with each essentially being a random distribution of crystals. My thoughts turn to the digital pipeline perhaps, but I exported using Prores and then it's compressed by YT, so if we compare that to someone that scanned film and then uploaded that to YT then my pipeline doesn't have anything in it that there's didn't, so if mine differs then it must be in how I'm generating things. This video contains lots of high-quality film examples from 8mm / 16mm / 35mm film shot in various scenes - I assume these look fine to you? (linked to a good timestamp) Interestingly, I just became aware there's an open source plugin under development that does all this stuff for free. It's still in beta phase, and apparently runs very slowly, but I'll be keeping an eye on it. https://spektrafilm.114c.de

Interesting about diffusion in the mids only (I think that's what you mean). It could be that film has different levels of detail in different tonal ranges. (I don't know.) These seem to have something not quite right about it to my eyes. The grain seems too fast, as in 30 FPS, not 24. Also the grain looks electronic and not chemical. Just something about it and the way it changes each frame. -

Big surprise on the price .I understand that they have made it entry level to their other cameras but to step up to the 6K Kinefinity Mavo mk 2 full frame which can do 12bit ProRes4444XQ and uncompressed Raw is US $6,000.
