Premiere Pro auto applying LUT on timeline

When I open a clip it automatically applies a LUT to the footage in the program and on the timeline. I am not able to remove attributes or presets as there are none. On the preview window is showing the footage as should be. I am using Premiere Pro version 22.1.2 (2022) and MacBook Pro (Retina, 15-inch, Mid 2014) on BigSUR 11.6.2

Hey Guys, our technician managed to solve the mystery. Just go to the raw clips, right-click and go to modify interpret footage. In color management it needs to be in rec709. In our case it was in sony slog3s gamut3cine That's it my friends, problem solved! Good luck in your work!

I have the same problem in adobe 23 now. It's impossible that we don't have a solution.

Certainly is frustrating. Fixing this is obviously not a top priority. My
guess is the software geeks have never been on a film shoot and have never
made a movie. And yet we are at their mercy. Go figure

If you'd like to actually get working without hassles, give the media & problem you're having. I'll be happy to help. And each different type of media may need slightly different settings, so full spedificity is needed.

Premiere doesn't actually apply LUTs everywhere ... they tend to use algorthmic transforms, an entirely different & vastly superior process for most uses. But if you don't understand the at times intriguiging controls, it's ... maddening for sure.

I'd recommend starting a new thread ... giving full details. I'll hop in and see if I can get this sorted with you.

Thanks Neil and everybody for this thread. I'm in a bind because Adobe's ongoing negligence has screwed up my work in a particularly bad way due to circumstances. Earlier today I color graded on one system that for some reason does not suffer from this bug, and now I have to finish and output on a different one which has added the automatic LUT to my color grading, with grotesque results. The given override solution was greyed out, I think due to the fact that these are composite clips I made to sync production audio. I was able to fix the original clips with the override, but that did not fix the composite clips that I edited with. I have a day to deliver this and had plenty to do before this insanely stupid bug reared its head. This may be a bit of a digression from the topic, but if anyone here were in this situation, what would you do? I'm trying to think if there's an efficient way to get to the uncontaminated version of the edit, but my brain is out of juice. Premiere Pro 22.6.1 build 1, Lenovo Legion 5

Ahh ... if you used Merge Clips to join the audio to the video, that's most ... unfortunate. That is NOT recommended if any 'turnover' of the media to another user or application is expected to be used.

The Multicam process is the preferred one for joining separate audio/video. Or "grouping" an audio & video can work for normal editing, without the limitations of Merge Clips. They cover 'joining' video and audio quite well in the new Adobe document on practical use ... and avoiding Merge Clips is one of the first things covered:

As to the clips, what is the meida involved? What color space? Is it 'normal' media or log-encoded?

Ahh ... now I know what's going on there.

That's a log-encoded clip, right? Did you know that all HDR is actually log-encoded? (Think ... Hybrid log gamma ... mixing log encoding with a gamma section ... )

The engineers completely rebuilt the underlying color system for the Pr2022 series. It used to be totally Rec.709 "with an ability to work with HDR media by using over-range values for dynamic range and color gamut" ... which was a cadged together way to sorta work in HDR.

This is clearly no longer a Rec.709 underlying system. It's completely agnostic for SDR/HDR media. Which is a huge improvement ... mostly.

But the default behaviors for some media aren't working as the engineers expected. Including ... some log-encoded media that is supposed to be simply log-encoded SDR/Rec.709, is being mis-displayed in Pr2022.

Pr2022 sees the log-encoding, thinks ... oh, that's an HDR clip ... and drops it into a sequence as if it were an HLG clip. WRONG.

Now the question ... some of the media it does this with, you can go to the clip properties via selecting the clip in the bin, right-click/Modify/Interpret Footage, and use the color management controls at the bottom of that dialog to "Override to Rec.709".

Then make sure the sequence is set to Rec.709, and work it and export it normally.

But ... for a few types of log-encoded media it does this with, the CM controls at the bottom of the Interpret Footage dialog are grayed out. And that ... is a massive problem.

So ... check your Interpret Footage dialog, see if you can Override to Rec.709.

Yeah sorry, I should say I am a novice so sorry about the miss understanding LUTs and monitor settings. The footage was shot on the Sony FX9 in SDR, 4k LOG. I am working off Premiere Pro 22.1.2 on a Mac Book Pro 2014 Big Sur 11.6.2 and the footage looks at expected in the preview window but the program window looks completely differenct once its added to the timeline. Ive attached the screengrab

Open the clip in Effect Controls and make screenshot of source tab.

Hi Peter,

Sorry. We definitely need more info on the camera you used to shoot the footage and whether or not the video was shot in HDR. Info on your system too, please as both Ann and Neil recommend.

Thanks,
Kevin

Premiere doesn't auto-apply any LUTs. This comment normally comes when someone is working with either a mis-understanding of setting their monitor systems or is unaware of the changes in color management of the Pr2022 version from previous behaviors.

So as Ann noted, we need information. Full details on the computer and monitor, where outside Premiere you're comparing it to say it's applying a LUT to the image.

We need to know the full details of the media, what produced it, what the clip properties are especially for color space.

And ... screengrags are always a good thing. Just drag/drop them onto your text reply box so they appear in your post.

Hi Neil,

I understood about 25% of your post but you solved my problem so you are clearly THE MAN. Many thanks!

[For the Record, I was working with some stock footage from a phone and Premiere was auto-applying the Rec.2100 PQ colour space to it, making the clip look different in the source and program monitors.]
