View Full Version : Final Cut Pro a no for 10-bit RGB Conform?

I want to conform a short film in Final Cut Pro with Red Camera footage in 1920x1080 RGB HD. My plan was to debayer the Red footage into 10-bit RGB Quicktime files and layoff to HDCAMSR in 4:4:4. From there I would have a tape-to-tape color-correction performed and re-ingest the footage into Final Cut Pro to conform the final product. But what I am reading on this site is that Final Cut Pro does not render in 10-bit RGB.
What is the suggested workflow when going to HDCAMSR tape?

You can process everything in 32 Bit YUV inside Final Cut Pro and use either 10 Bit YUV ProRes or 12 Bit RGB Cineform as your sequence settings.
You may or may not notice any artifacts from the YUV-RGB conversion depending on the type of footage. Do some tests and see if it's a problem for you.
What 10 bit RGB codec were you planning to use?
You would need to use plugins in FCP to render transitions in 10 bit, see here for details:
I'm just working on updating these articles with some new info but the basics are there.

I am interested in using the AJA 10-bit RGB codec. I have not used the Cineform workflow before. I will look into that thanks.
I can set the Final Cut Pro timeline to render in high-precision YUV when using 10-bit RGB? Is that an RGB-YUV-RGB conversion that is taking place?
I could also create the effects and transitions in a program like Shake or After Effects and import them into my timeline correct?
When creating the Quicktime files in RedCine what kind of Gamma settings should I be using?

no, you cannot set FCP to render in high precision when you are using an RGB codec * You can only set FCP to render in high precision when you use a YUV codec then everything will render in 32 bit YUV.
If you are doing a linear workflow then you'd want the REC709 gamma from RedCine.
yes you could also render all effects and transitions in AE by using Automatic duck to convert your whole timeline to an AE project, then you can render everything in 32bit 444 RGB. This is a lot more work and might not give you an perceptible gain, you'd need to test it.
* Some codecs "lie" to FCP and pretend to be YUV when they really write RGB data.
