FX6 log footage converted to rec 709 issue

@Mattie P. Sorry for the confusion here: in hindsight, we should not have merged these posts, as they do appear to be two different issues. I'll reach out to you via email and we can set up time for a call.

Hi @Fergus H and @IanB_360 I'm still having this issue having removed the Catalyst plugin completely from my system. This time my process is importing media from both the Sony A7S3 and FX6, right clicking the clip in the Project panel and going to Modify>Color>Override Media Color Space and setting that to Sony S-Log3/S-Gamut3.Cine (what both cameras were set to record). Suddenly that clip turns into awful blown out highlight electric kool aid crap in the source monitor. If I return the setting to Use Media Color Space: Rec 709 then it returns to the flat recorded Log image that I would expect to see with nothing applied to a clip straight out of the camera.

I know you merged my issue with another person's but I'm not sure whether it is the same issue or not. Either way, it still persists. Thanks!

@Mattie P. You don't need to be using the plugin for it to potentially cause an issue; it just needs to be installed. 

The easy way to test whether a plugin is effecting your workflow is to disable it. You can do that by holding down the shift key, then launching Premiere Pro. Chec the last option - to disable plugins - then try your project again.

OK... @IanB_360  can you confirm this is happening even without using Catalyst? I have it installed on this system, but at no point did I open it while handling this footage. In fact, I don't think I've opened it since installing PP2025!

Premiere Pro 25.1.0 (Build 73)

Windows 10.0.19045 Build 19045

NVIDIA Studio Driver 566.36 (GEFORCE RTX 3080)

Ryzen 9 5950X

This is my first export since updating to PP2025. Exporting a basic string of selects for client. Shot on Sony FX6, UHD XAVC-I at 59.94. Sequence settings match that. I have an adjustment layer for basic color grade. Here is the problem:

1. Ctrl-M to export active sequence

2. Export dialogue opens.

3. The frame in the Export Source monitor is suddenly glowing with highlights way blown out. Completely different from the active frame in the Program Monitor. This effect is applied to the export.

4. Disable the Effects tab/button and the strange glowing effect goes away and all is normal. There are, however, no boxes checked under the Effects dropdown.

5. Expected result: The Effects tab is active by default. I have never had it apply an effect in previous versions of Premiere. Actual result: Now it is applying an effect, despite no checked boxes and it still being on by default.

Here is the frame grab from the Program Monitor:

And here is the exact same frame in the Export dialogue having touched no settings:

@jamesg15414133 Thanks for the follow-up; I appreciate you getting back to me. I'll reach out to you via email and let's find a time to chat on a video call.

@IanB_360 @Fergus H Unfortunately no luck by resetting the media cache or the suggested steps, attached you can see to snaps , one with the image enabling the Auto Detect log video clor space and the other one disabling the Auto detect log video but as you can see the 2 images are absolutely the same not changes there.

Please let me know if you have further suggestion at what could it be.

Thanks

@Fergus H Thanks for the suggested options, I tried in another new project with different log footage and Istill getting an automatically rec 709 applied to my log footage, I've also use Davinci just to see what my footage looks there and i was able to see a flat log footage in Davinci allowing me to add my preset colours and rec 709 conversion.

Will try to reset my media cache tomorrow and will let you know

Thanks for the input, please let me know if you have found further options to try.

@R Neil Haugen as @Fergus H mentioned Auto tone mapping should not effect my log footage,

I want to see the log footage in premiere pro and be able to use my own rec 709 converstion and not an automatic rec 709 coversion from premiere as for some reason the one from premiere mess with my luts and final color grading ,plus my current work flow help me to achieve better colors and the work flow for my productions.

Thanks for the input
