Transcoding is transcoding, with 'generation loss', no matter how much that will hurt.
Re-wrapping (aka Avid consolidate old style) is 1 to 1
Re-wrapping on non I frame only codecs IS possible, but that means jump hoops. (Copy from I frame, set a new file start, not many apps can do this, but it IS possible.)
I'm behind, my Avid version is old, won't even run anymore, so I can't check, but in the past I've never had issues with FFmpeg generated ProRes nor DNxHD.
(And I think my work has generated tons of clips for numerous studios.)
Paging Marianna, can I PLEASE have a developers licence?

It isn't a re-wrap, which just puts the video essence in a new container.On Fri, Nov 20, 2020 at 7:26 AM John Moore <bigfish@pacbell.net> wrote:Now my generic question is, "When I take the specialize Lavc57.24.102 netflix proreshq 3840_2160 file and transcode it to a new proresHQ file does AME degrade the proreshq video essence in the process or is it just passing the ones and zeros through and creating new compliant metadata. In old linear terms am I doing a head wheel to head wheel dub or a composite video signal to get remodulated into a dub with a generation loss. Given it's the same codec proreshq I'd hope it would be a non loss process. Just curious.
