export using Blackmagic 10 bit yuv
Hello,
I’m trying to finish up an After Effects project and I’m having a slight output issue with Final Cut.
I’m exporting my project from After Effects encoded using the Blackmagic 10 bit yuv codec. Everything looks great, no chroma or luminance shifts. I import to Final Cut to join the pieces of the project and lay down the final audio mix.
The issue I’m having is when I go to export from Final Cut using current settings, the exported clip uses Apple 10 bit instead of Blackmagic 10 bit and I’m getting a slight luma and chroma shift in the new clip. The really weird thing is if I set in and out points in the middle of the sequence to be exported, the clip it exports uses the Blackmagic 10 bit codec and there is no longer any shifting.
When I go to try and force Final Cut to use the Blackmagic 10 bit codec using a custom setting, most of the Blackmagic codecs that were available in After Effects are no longer there, leaving me with only “Blackmagic 8 bit (2vuy) and Blackmagic 10 bit RGB, both of which introduce chroma and luma shifts.
This thread from a few years ago addresses some of this issue, but there isn’t an answer given to the last question, which is where I am at.

Hi Graham,
The BM 10b is a legacy codec..
BlackMagic uses the Apple 10b Unc codec since long time.
Those codecs are still available for reading all stuff.
You should use the Apple 10b Unc.
Cheers,

I’m aware that Blackmagic uses the Apple 10b uncompressed codec and I’ve tried using it already, as stated in my original posting.
When I export the entire sequence as Apple 10b uncompressed, I get luma and chroma shifts. When I set the in and out points somewhere in the sequence, for some reason, it spits out a clip as Blackmagic 10b, with no luma or chroma shift.
Thanks for your response.

So export from AE with the Apple 10b Unc and make all the way with this codec.
In fact I would recommend you to uninstall the BM codecs.
Unless you have some old material encoded with those, there are no much reasons to keep them.
just take them out of the QT folder (main Library) and let them somewhere else.

Hey Rafael,
Yup, that’s what needed to happen. I was trying to avoid re-rendering because of the time involved, but I ended up baking a few of the comps to speed things up a bit. For some reason I had it in my head that I was trying to avoid chroma and luma shifting by using BM 10bit, but upon further testing, I was getting no shift using apple 10bit uncomp out of and back into After Effects.
I think I may have read a post from a few years ago recommending BM 10bit. The other thing pushing me toward that was the fact that with BM codecs installed, uncompressed 10 bit isn’t given as an option.
Thank you for your time and you suggestions.
