Here's my question: What gamma is my FCPx on, when my color space is set to Rec709?
Can I safely assume that with my Display Profile being set to Rec 709 Gamma 2.4, FCPX applies Gamma 2.4 as my working and output gamma?
I did a few tests and am fairly suspicious, hoping someone here can enlighten me on this:
My workflow is as follows:
My Mac OS X 10.15.3 Macbook Pro's Display profile is set to Rec.709 Gamma 2.4
I use DaVinci Resolve Studio 16.2 for my color grading and FCPx 10.4.8 for my Editing.
1. Graded a file in Rec 709 Gamma 2.4, exports it out using Resolve with the same 709 g2.4 tagging.
2. Opens it up in Quicktime Player 10.5, great, consistent colors with my Resolve viewer.
3. Imports it into FCPx, and I see a difference between Quicktime Player and FCPx
It seems that Quicktime Player is able to read the embedded gamma and transform/display it such that it is accurate with my Resolve viewer,
which begs the question, shouldn't FCPx do the same thing since they are both directly affected by the Display Profile selected? I have some screenshots attached to show the difference between the three applications (Resolve, QT Player, FCPX - using this workflow)
It seems that FCPx viewers do not use the gamma of 2.4, but possibly Rec 709 gamma that one could argue would be around 1.94.
Does anyone know if there is a way to monitor at gamma 2.4 using the FCPx viewer like how QuickTime does?
Or am I missing anything?
FCP uses the default color profile with ColorSync to maintain the appearance across applications. The display profile doesn’t alter the output. You would need to check the output on a broadcast monitor.
I do broadcast daily, don't have a broadcast monitor (cheap management), but I do just fine using the scopes. Learn to use your scopes and you'll be fine. And slap on the Broadcast Safe effect if you're feeling shakey about it.
