Hi Carl, I have now tried this command:
HD_BARS.mov -s pal -vcodec prores -profile 3 -vtag apch -an -movflags +write_colr -an -s pal -color_primaries smpte170m -colorspace bt470bg out.mov
Using this ffmpeg output now matches the SD sample I sent you:
yuv422p10le(bt470bg/smpte170m/unknown
BUT the output is still wrong, much too bright.
Here is the current output:
ffmpeg -i HD_BARS.mov -s pal -vcodec prores -profile 3 -vtag apch -an -movflags +write_colr -an -s pal -color_primaries smpte170m -colorspace bt470bg out.mov
