Hi Carl, your last command: ffmpeg -i HD_BARS.mov -vf colormatrix=bt709:bt470,scale=pal -movflags +write_colr -color_primaries smpte170m -colorspace bt470bg -vcodec proves out.mov At first all looks good, until I apply a gamma filter to it and turn it up, exactly the same issue as we started with, lots of artefacts have been introduced.
