I'm pretty sure there's ways of muxing v210 in mxf, so it might be
better to say nothing here unless we're entirely sure. Probably OK
since mxfenc can't mux raw video tho

IIUC we need this for SMPTE 386M (D-10). It lists "Padding Bits"

this needs to be updated in case rawvideo support is added with different
padding bits.

will apply
