It works semi successfully but lutrgb leaves behind some errant pixels which are > 235 or < 16. Just save the script into a text file (e.g. 444p-to-420p.sh ), make it executable with the command chmod u+x 444p-to-420p.sh, and run it from within your videos directory. Hint: If you store it in a folder called bin in your home directory, it can be executed by only its name from any other folder without having to enter the script's full path.ffmpeg -i TESTCASE.mkv -pixel_format yuv444p -color_primaries 1 -color_trc 1 -colorspace 1 TESTCASE-yuv1.mkv You can add -color_range too. Also yuv420p and yuv422p are "broken" too.I found that yuv444p h.264 files are much slower to decode than files of yuv420p. For example, I have some 1900x1200 48-fps video files with the following decoding speed: - x264 lossless yuv444p: decoding at 30 fps - x264 lossless yuv420p: decoding at 80 fps (the files are generated by ffmpeg/libx264 from the same source usingffmpeg -i test444.mp4 roundtrip.png You should see no black pixels. Update: ffplay downsamples YUV inputs to 420 before final conversion to RGB.
