No, FCP is not exactly a requirement for FFmpeg development. I tested the following: $ ffmpeg -i HD_Source.mov -vf colormatrix=bt709:bt601,scale=720:576:flags=lanczos -vcodec prores out.mov $ ffmpeg -i out.mov -f rawvideo out1 I then compared the output file out1 with the following file (the color filter defaults to black): $ ffmpeg -f lavfi -i color -pix_fmt yuv422p10 -f rawvideo -vframes 1 out2 The luminance of the files is very similar. Are you reporting different chrominance values for zero luminance?
