Adjustment layer changes gamma?

[Noah Kadner]

What format is the footage? It might be getting rendered to a different color space than it was shot in originally. You’re only seeing that on the letterbox because its forcing a render vs. just playing back from the original format.

Thanks for the reply Noah.
The format is XAVC HD @ 100Mb/s (from a Sony FS7). I also have GoPro H264 clips in the edit which behave the same as the XAVC.
Have tried disabling the adjustment layer then applying an effect, to force a render, this does not create a shift in gamma though?

Sorry. Correction to my last post.
The GoPro H264 clips behave in the same way as the XAVC. i.e. the adjustment layer forces a gamma shift.

A gamma shift where- in FCPX? Or in the finished footage playing out to a broadcast monitor?

Gamma shift appears in FCPX UI, on monitor via Black magic Ultra I/O & on exported ProRes file.

What are you using as an adjustment layer? Have you tried a different adjustment layer? What effects are applied to it? What happens if you apply the adjustment layer over footage in a new project?

Just wondering if it’s the adjustment layer, or something applied to it that’s causing the colour shift.

Using the adjustment layer from the text browser. Didn’t know there was an alternative? Please advise.
Applying a letterbox crop.
Same gamma shift when in new project.

Have solved the issue.
Opened the adjustment layer, from the text browser, into motion. Changed nothing then published it to FCPX.
All ok now. No idea why?

Might have had something hidden someplace that caused that shift- hard to say. In general I find copy/paste attributes a lot more predictable/useful than adjustment layers which are really more of a workaround in FCPX and not so much a built-in workflow.
