I did create a different thread with screenshots, but it went to moderation and was never seen again (I don't believe it broke the rules at all, as I read each one - I've not received a message or notification about the thread so assume it has been lost).įrom testing, I've found (perceived rating out of 10): Sensible flags, such as veryslow for x264 and tuning for grain, and not tuning for grain on x265 but using slow and changing options manually that should preserve more grain, but with speed optimisations (just to get a rough idea of the output). All encodes were 10 bit to create a level playing field (as much as possible). I have done this to see what sort of difference it makes to the grain quality (I apologise if that doesn't make sense to anyone else).įor creating a 'perceived rating', I tested scenes with motion, darkness, detail, edge detail (plants in the corner), and other small details. However, I have played around with heavy noise removal using x265 and x264 built-in noise reduction. I've spent about 80 hours reading threads on doom9 the x265 documentation over a two week period. The aim of my experiment is to keep the grain, or as much of it as possible - or perceivably possible -, for the bitrate allocated. I've spent about 30 hours testing the same four minute clip of a very grainy source using 2-pass 4,500 kbps to control for size and bitrate (for comparisons), as well as a couple of CRF encodes thrown in to see what bitrate would be required (for x265).
