Thats a bit of a show stopper! A real shame the colormatrix filter has this limitation. Any chance this will get 'upgraded' to support 10 bit, or perhaps a patch?
Or is there any other way to convert from bt709 to bt601 in 10 bit?

Using that in my command line gave me the closest conversion I could achieve, now I know why it wasn't perfect, no colormatrix 10 bit support!

I guess it's time to throw the towel in and give up, back to avisynth :(

Thanks for all your help Carl, appreciated.
