Hi Carl, I think you misunderstand. We have the HD file (bt709) which is the HD_BARS.mov, sample and readout log already provided, which I want to goto SD_BARS.mov (bt601). The last line of code you provided was almost perfect, log readout already provided:

ffmpeg -i HD_BARS.mov -s pal -vcodec prores -an -movflags +write_colr -an -s pal -color_primaries bt709 -color_trc bt709 -colorspace bt709 out.mov

This was great, but the out.mov is still flagged as bt709, but needs to be bt601. What would I change in your code to correct this please?

Kind regards.
