FCPX Timeline Footage Dark & Saturated in Viewer

First off, I am well aware of every single post in the following thread, which are of no help whatsoever:

Very very dark video in FCP X viewer. - Apple Community


PROBLEM: I restored a MacOS High Sierra drive backup from TimeMachine to an external 2TB SSD then booted my mid-2015 5K 27" iMac from it, but I sadly discovered that although footage thumbnails in the left sidebar look fine and while hovering over those thumbnails displays great looking video in the viewer too, those same clips on the timeline look dark and saturated in the Viewer.


FAILED Things I've tried:

  1. Press Opt & Cmd while launching FCPX to create new preference files.
  2. Start afresh with a new "standard" library, new event, reimport footage.
  3. Confirmed there are no Effects whatsoever causing this.


What Sort-of Works:

System Preferences > Displays > Color > SMPTE RP 431-2-2007 DCI (P3)


But that isn't the profile I normally use because it makes everything a bit too bright for my taste.  Interestingly, the calibrated profile (calibrated with Apple's software calibrator, not any third party device) I normally use doesn't work to fix the FCPX viewer darkness and over-saturation problem.  In fact, most of the profiles which looked rather decent before (when I had High Sierra on my internal SSD) now display FCPX timeline footage too dark and too saturated in the Viewer.


I launched ColorSync Utility and did a Verify & Repair on my profiles, but that didn't resolve anything, even though it made some fixes. 


Again, only SMPTE RP 431-2-2007 DCI (P3) eliminates the darkness and over saturation in the viewer (when viewing timeline footage).  But it is not an ideal solution because, like I said, it makes everything a tad big too bright, almost like it has a brighter gamma.  I should be able to use the profiles I always used, but for some reason they appear broken, and ColorSync Utility's Repair feature doesn't resolve the issue.


Any suggestions would be greatly appreciated. Thank you.

I am using FCPX version 10.4.6 under High Sierra, the newest version available to download under that OS.


People unfamiliar with the GH5 often say what you did, but the fact is that HLG offers the same great dynamic range as vLog (the maximum the camera offers), yet without the additional $99 fee. There are no other camera profiles in the GH5 that offer such good dynamic range. As such, I shoot exclusively in 10-bit 4K HLG and have been editing that way for years in FCPX. I had zero issues in High Sierra on my 5K iMac and my mid-2015 15" MBP, no issues on my kid's 2017 MacBook Airs, and no issues on a modern M1 Mac running MacOS Monterey either. It's only the restored High Sierra drive backup that first presented the issue, and I just don't understand why.


Why boot from High Sierra anymore since I am now running Mojave on my 5K iMac? Well, Mojave seems to have a bug that affects my internal SD card reader. I posted separately about that today. I wanted to check and see if the problem went away under High Sierra, which prompted me to restore my backup to an external 2TB SSD. It was then I noticed that (1) the SD issue is solved in High Sierra, but (2) after clicking on the timeline footage to make it display in the viewer, the footage is quite dark and overly saturated. That in turn prompted me to report that in this thread.

Camera: Panasonic GH5


I would be happy to tell you about Clip & Timeline properties, but I will need to know what specifically what you want to know, seeing there is not "Properties" command in FCPX that I can invoke. If you mean "info in the Inspector," then please specify what info found there that you would like me to provide. For now, I see this relevant info in the Inspector (with "Settings" chosen in the popup):


3840 x 2160 | 29.97p Stereo | 48kHz

Rec. 2020


Color Space Override: Rec. 2020

Camera LUT: None


Thank you.

The application is designed to work across the platform using the default color settings for the system monitor, whatever is at the top of the list in the display settings.


As far as I can see from the Panasonic website the GH5 does not shoot HDR video so I don’t understand why you’re seeing it as Rec 2020 and not Rec 709. Perhaps this is a firmware change.


What version of the application are you using in High Sierra?
