Desktop Reels have an unwanted display transform

Hi, I while back I worked on some shots in ACES, but mostly the project is standard post grading retouches.
Some modules like the Stabilizer for example always showed me the wrong display transform until I changed them in the view settings.
Since them somehow the Desktop Reels still show me a wrong display transform and I am not able to find the place to set the transform back to Video.
Creating a new user did not help.

Can someone give me a hint where to set the view transform for the Desktop Reels? It is just annoying, as soon as I enter the player, the sequence looks fine.

I realised that the thumbnails in the MediaHub show the same wrong Viewing Transform.

I think I found it now by myself.

I crested a Viewing Rule for the ACES comps and this was still checked. By unchecking it the wrong display transform is gone.

Thanks for following up!

Woe… hold your horses! I’m currently experiencing this on a new project. Not in ACES. Project is set to legacy. Tagged all my mxf files from rules and they came in with expected slog3. I forced a tag to slog3 from the b camera (a7s) to slog 3 as they were mp4 files. (should the mp4 file carry CS info??)

I’m seeing the same problem as @toodee and that the player displays the image correctly (log looking but the reels/freeform proxy are showing a rec709 view transform on them…

wait… light bulb moment…Just checked User prefs and there’s a checkbox for desktop colour management. - Apply Colour Management

I’ll leave this post in case someone else has the issue. And to all of you that knew the answer sorry for the waste of bandwidth.

Hi @johnag,

thanks for the info. I forgot to mention that I got the problem on an older flame machine still running 2020. I don’t think this preferences existed then?



I think you are correct. It must have snuck in at around 2021 ?? @fredwarren ??

Where are these user prefs?

I see them in the 2023 beta under prefs/User Interface ‘middle left down on the page’.

Ah, sounds like a new feature for 2023, I’m still on 2022.

This preference has been there (in Preferences > User Interface tab > Thumbnails section) since we introduced the new Colour Management system in Flame 2017 Extension 1.

Interestingly @toodee the hierarchy you have in the viewing rules is how your thumbnails will be displayed on your desktop.

If you have multiple log-c LUTs, the top one is the one that the thumbnails will use for log-c clips.
