Final Cut Pro 10.8.1 - problem with HDR videos since upgrading to MacOS Sequoia

Hi everyone, since I upgraded to Sequoia, HDR videos shot on an iPhone 14 Pro Max appear too dark in FCPX. Even when I open previous (finished) projects that looked fine under the previous version of MacOS, it does not show correctly.


After I treated my project as best as I could (but really not to my standards), if I export it to Compressor it then appears completely overexposed.


My screen is HDR and I enabled HDR in MacOS' setting. My Mac is a Min M2 Pro.


Anyone else encountered this problem ?

Mac mini, macOS 15.0

AlainBE, thank you, PF_Productions, IAmSkipperMark, Tom, Clint, and Luis *very* much for all your help on this. Re: why it's not sorted out: I don't work for Apple, but I have extensive experience in software testing, development, and escalation support, and I can explain how the system works.


  • Usually, nothing will get fixed solely by people talking about it on a forum. From a user standpoint, it feels like you've "reported" it, especially if details are given, but that will not normally result in Apple product support or engineering taking action. With some products, such as DaVinci Resolve, actual developers monitor the forums, but that is rare. There is also a valid argument it's not the best use of a developer's time.
  • Posting info on a forum is useful, and the more detail, the better. In this case, several users have collectively posted enough information to broadly understand the overall problem parameters. But took a while.
  • There have been numerous situations where users refuse to provide the requested info, such as an EtreCheck report or an error log. This can greatly delay problem resolution.
  • For complex hardware/software issues like this case, posting information on the Apple Product Feedback site is OK but will often not produce the desired results. That site allows just 800 characters max input (including spaces) and no ability to attach files, error logs, links, etc. It is simply not designed for that purpose.
  • There is an Apple Feedback Assistant app, but it requires a developer account and is generally oriented toward app developers, not end users, and not even sophisticated IT users.
  • The best approach for most users is to collect as much info as possible and then contact Apple Support. If the case is escalated, this can include ongoing two-way email discussions whereby you report new findings. I believe this particular case is in that state, and IAmSkippermark is driving this (thanks!)
  • If you are an experienced software developer or have done similar work, you can get an Apple Developer account and report the problem, including attachments, logs, and files needed to reproduce the issue. However, this can require lots of work if done properly. When bugs are filed this way and followed up by contacting product support, Apple has been very responsive. See attached for an example of one I filed.


However, there is a good argument that customers should not have to spend hours or days researching a bug. OTOH, those customers may spend hours or days discussing the bug on a forum, so time is being spent anyway. There is no simple solution for this, but it's important for everyone to understand what is required to get a bug fixed.


The fastest way to get a bug fixed is by achieving a specific (ideally portable) reproducible scenario and reporting it to Apple Support by opening a case. The scenario allows engineering to reproduce the problem under a debugger and quickly fix it. It also allows later testing of that scenario to ensure it stays fixed in a new software version.


But it can take lots of time and work to achieve that well-documented, portable replication scenario. When working on critical problems that I or others encountered, I've heard people say "You're doing Apple's work for them." That betrays a lack of understanding about how the system works and how serious some problems are. If not for these efforts, some problems would not be fixed in an expedited time frame, and the cost to some end users could be significant.


Errorlogs and crash logs are useful, but those by themselves may not enable fixing a bug. The underlying technical factors are too complex to explain in this post, but if anyone is interested, I can elaborate in another thread.


Incorporating even a single fix to a complex product requires a full battery of regression tests, stress tests, functional tests, performance tests, localization tests, and security tests, individually repeated on a complex matrix of platforms and configurations. If the fix involves interactions between FCP and MacOS code, it might require a MacOS update, and those have their own schedule. The fastest I've seen Apple implement an FCP fix was about three weeks from the initial report, and that was a highly urgent matter where the release contained only that one fix.

I have this problem too, with fcp 10.8 and 11.2. and macOS Sequoia. I'm using a Powerbook pro M1 16". I installed Sequoia on an external drive, just the OS and fcp 11 and compressor. I noticed something what hasn't been said here. On the picture on the left you have a screenshot from tcp on an external monitor (LG). The monitor is the only screen used. In the middle you see a shot from the LG used as extended monitor after I dragged it from the laptop screen to the LG. On the right a screenshot on the laptop monitor. This could be a temporary solution for laptop users but as soon as you close the lid of the Powerbook it becomes dark again. This happens in FCP 10.8 and 11.2.

Of course, thank you for replying !


Library is HDR Wide Ganut


Project is 4K, 3840x2160 30p, Apple ProRes 422, HDR Wide Gamut - Rec.2020 HLG


Clips are all 3840 x 2160 60p, Rec.2020 HLG


Imported clips look great when played from MacOS' finder, but are too dark once imported in FCPX.


Once I get the video barely acceptable in FCP, the rendered file is overexposed.

Sep 23, 2024 7:50 AM in response to AlainBE

So the thing to figure out is if it's how your Mac is communicating with your specific monitor or if it's a general problem that applies to all HDR . This seems unlikely or there would likely be loads of posts about it. I've not installed Sequoia yet and don't intend to for a while so can't test directly. I will try installing it on an external drive later to check it out on my MacBook Pro XDR monitor to see if I am getting the same issue


Anyway I'm not entirely clear what is happening but you seem to be saying that Quicktime Player shows the original clips as HDR but the clips rendered by FCP are not showing as HDR either in FCP or Quicktime. When you have clips opened in Quicktime and open the Movie Inspector, Video Details, Code Points what numbers do you see for the original clips and those rendered as HLG by FCP. For HLG HDR you should be seeing 9-18-9 tags.

Sep 23, 2024 12:57 PM in response to AlainBE

OK so I installed Sequoia on an external drive connected to my M1 MacPro with XDR screen, set to HDR P3-ST2084 display preset (the correct one as recommended by Apple and the one I always use), and I installed the latest version of FCP. I am not having any issues seeing HDR video (PQ or HLG) properly - not washed out, not interpreted as SDR in either the Final CUt viewer or rendered in Quicktime and they look identical as usual.


I suggest you check the color conform settings for your footage to see that it is not being interpreted as SDR. If so then change it manually to HLG. Otherwise it might be something to do with your monitor not getting the correct HDR signal from your Mac? In any case, it doesn't appear to me to be a general problem with Sequoia.

Sep 27, 2024 11:30 AM in response to Clint Gryke

Thank you again for your efforts; much appreciated !


I am back home and decided to try again with a new project. So I created a new Library (Wide Gamut) and a new project with automatic settings taken from the first imported video and everything seems to be working as normal.


The only thing I can think of is that the project I was working on before I upgraded to Sequoia did not "support" the new OS.


I am sorry if my problem made you waste some precious time.

I am also having this issue! I'm on an M1 MAX and FCPX 10.8.1. I use an external monitor and it gets HDR from the M1 from everything via the HDMI port EXCEPT FCPX! Its all muted down. The screen on the laptop shows HDR footage in HDR. However it won't output via HDMI port to a monitor in HDMI from FCPX. I've tried everything, including making a new library. Like I said it shows it as HDR in FCPX but it will no longer output via HDMI in HDR.


I have changed display settings several times, the monitor I'm using will show HDR photos etc, just nothing out of FCPX via the M1's HDMI port.


I believe this is a bug with either Sequoia or FCP 10.8.1



Oct 2, 2024 8:17 AM in response to Tom Wolsky

That's exactly my point Tom, it won't show as HDR out of FCPX from the HDMI!!! I have it set as extended display. And then in FCP I always use that for just the program output. Has worked perfectly since I got the M1 MAX. Now it won't output HDR in FCPX to the monitor. It used to, now it doesn't! All I did is upgrade to Sequoia. When it's being used as an extended display in any other mode (editing photos in lightroom, showing a mirror of my display etc.) it outputs in HDR as I showed in that photo where it says "HDR".


I appreciate your interest in this, but I've troubleshot it for hours and it's just not working in FCP to output an HDR signal over the built in HDMI on the M1 Max with Sequoia.

Thanks Luis. Yes, I should've clarified that. In FCPX it's AV Output. But in System Settings I have to put that 3rd monitor as "Extended Desktop" and I have to enable "HDR output". Two different locations.

I think this is relevant, and it is also relevant that taking a screenshot apparently shows things correctly, whereas a photo of the screen exhibits the problem.


So, two observations:


1) The file appears to correctly encoded, and the problem lies in how it is sent to the external display.

2) It would be interesting to know what happens if you set the Viewer to that display, instead of AV monitor.

Would the media played back on the viewer, on the external display, show as it does in the internal, or as it does in AV monitor?


And - sorry if this has been asked and answered before - what is the Color Profile selected for the external display? Could that be the problem?

Oct 3, 2024 6:28 AM in response to Luis Sequeira1

Luis,

1) Correct!

2) If I mirror the Built in display to the external LG TV, it shows it in HDR! But it's less than ideal as it's not a full screen image. It's the Final Cut viewer with the rest of that info on the screen and the image I want to view is smaller within that frame.


I sent a bug report in to Apple via Final Cut Pro, I'm not a developer or have any betas.


I'm curious why no one is noticing this though? Does no one edit HDR on a laptop and output a full screen image to a large 50" or larger TV? The HDMI is right there on the machine so it's so simple to set up!


Thanks for the help everyone, I hope they address it soon in the next update.

I encountered this problem on the first day of the public (not beta) release of Sequoia 15.0. Immediately contacted support and have talked to several advisors since with no resolution in site. Editing to add that the 4th person I spoke to elevated the issue to an engineer about a week ago, but the engineer hasn't gotten back to the advisor yet. This happens on my M1 desktop all the time and my Mac Laptop when it's hooked up to an external monitor. It doesn't happen on the laptop's internal screen.


I'm working with an LG C3 color calibrated monitor that's hooked up directly to the HDMI port (not going through an UltraStudio type device), but I tested it with 3 consumer-grade HDR monitors ranging in price from $300 to $1500 on both machines.


When working with an HLG project, all HDR clips appear dark in the browser and the viewer when I hover over them in the browser and the timeline. When I switch the project to PQ (including setting the proper monitor's metadata in the project settings), the clips display fine in the viewer if I hover over them in the timeline, but they display dark in the viewer and the browser when I hover over them in the browser.


I tested several different projects using footage from several different cameras, and they all have issues. If I open those same projects on a Mac with Sonoma, they work correctly.


I have been working with HDR timelines for over 5 years and know how to probably set up the project types and edit/conform footage between color spaces.


To test more, I went to an Apple Store and tried to duplicate the issue on a Mac mini and a Mac Studio that were hooked up to the $1599 Mac Studio monitor via USB-C, and I couldn't duplicate it. So, it either seems to be an issue with the computers talking to the monitor.


I typically have edited and exported my HDR projects in HLG, but I have since switched to editing in PQ. The clips are still dark when I hover over them in the browser, so it's difficult to mark in/out points, but they look fine once added to the timeline, so I can work with it.


This issue does not occur with DaVinci Resolve Studio 19.0.1 or 19.0.2, which was released yesterday.

Oct 3, 2024 6:45 AM in response to Clint Gryke

Hey Clint, I'm having this same issue on my LG C3 and 3 other monitors and not going through a that I tested. They were all hooked up directly to the HDMI port and not going through an UltraStudio type device. I went to an Apple Store and did some testing using a Mac mini and a Mac Studio, which were both hooked up to a Mac Studio monitor via USB-C, and I couldn't duplicate the problem. It seems it may be an issue with MacOS talking to external monitors or possibly when they are connected through HDMI. My monitors don't support USB-C, so I can't hook them up that way to verify.
