Dear Kevin,

to my knowledge, the -vf scale colormatrix=bt709:bt601 is not designed to write the metadata you are searching for. It only converts the standard.
In order to use 601 Metadata, you have to dump metadata from a file or define it yourself.

I have not tried it with Prores so far, but in x264 it works like this: -x264opts colorprim=bt709:transfer=bt709:colormatrix=bt709
