[Christian Stoehr] “When exporting Pro Res422HQ as a roundtrip with FCP everything looks as in DaVinci, but now for my final roundtrip I want to go out ProRess444 and I get a luma shift.”
Its probably more than just a luma shift… what is the source codec?
My observation to this point is that ProRes444, although it is tempting to take advantage of nominally wider bandwidth, is truly only good for preserving either alpha channels (although the round trip from Resolve does not port-through the alpha), or maintaining RGB flow-through. FCP, however, seems ignorant as to how to scale PR444 material which may or may not be Y’CbCr or RGB, depending on the XML flags on the return trip. This will lead to misinterpretation of the media on decode.
