hmm, maybe I should just say that copy is not supported for DNxHD files then as that sounds a pain to deal with, or I could put better check in the arbitrary buffer offsets the mov_write_avid_tag function uses to access track->vos_data, which is what sent me down the direction of trying to access the encoder data. Is there a sensible function I can use to find a specific atom within the buffer? On a related note when doing a -c copy is it supposed to preserve color range (trc, space, primaries) in the output if it is set on the input/command line?
