Annoying color shift with text overlay
A doc I just edited came back to me from the colorist as Pro Res 4444. I dropped it into the timeline to add lower thirds, titles and so on.
I’m using the basic FCP titles. When I add a title and render, there is a noticeable – and unusable – shift in the brightness level. Even if I export a Quicktime, you still see it.
When my footage was PR422, there was no problem. Now that I’m editing in a PR4444 timeline with PR4444 footage this is happening.
Is this a common problem that I’ve been lucky to miss or have I F-ed it up somehow? Any ideas? THANKS

So why not transcode to 422 and be done with it?
If it is already graded, and the source was 422, for what reason would you need 4444?Bouke

Make sure you sequence settings are set to the highest.

Sounds like the ProRes 4444 files are RGB and you are rendering YUV.

[Bouke Vahl] “for what reason would you need 4444?”
The simple answer is that there is a widespread belief that “bigger” is better, whereas “the same” is the correct approach, because there is no gain in using the 4:4:4:4 container, but it does make the anticipated codec decoding ambiguous.
The shift is pretty much a proxy shift, rendered outside of the normal Y’CbCr/RGB precision rules.
