Oops, discovered I had a typo in the preset for x265. pix_fmt=yuvj420p does work with x265 as well. Problem solved.
Hi, There are many threads here and posts online about washed out colours when rendering/transcoding from sources such as smartphones and cameras. I have read many of them and have run many trials for a weeks time, but can still not wrap my head around what the central problem is and what to do about it. It appears to have to do with limited colorspace for TV standard 16-235, instead of 0-255. Mediainfo shows a "full range" color space in input file while the render is "limited". Some people say flags are incorrectly stated in the source files. For x264 I have been able to remedy this by including the flag pix_fmt=yuvj420p. But that does not work for x265. Neither does color_space=pc. It makes no difference whether I scale or retain original resolution. I can transcode to Prores 444 but when trying to render that *.mov into x265 my computer crashes. My GPU is really old. CPU Ryzen 5 3600 not super powerful either. In Handbrake I manage to retain the non-washed out colours by transcoding with its x265 12-bit preset but I don't know how to achieve that in Kdenlive. Is it possible to maintain the saturated colours and the punch of the source file when rendering with the x265 codec? I would prefer 265 to 264 since I can get smaller file sizes that way. Here are two images showing the wasking out between originalk and x265 rendered output. Also I include the Mediainfo from the source, a successfully rendered file with x264 and a washed out render with x265. Original Washed out
