P: Bug: Lumetri Color Panel will not preview LUTs when applied to Adjustment Layer

[Motoed-Hidden]

• Issue - When attempting to apply a creative LUT to an adjustment layer, the selected LUT will not preview in the Lumetri Color Panel. If I apply the same LUTs to source footage and not the adjustment layer, they will preview.  
• Adobe Premiere Pro version number: 24.6.1
• Operating system - macOS Sonoma 14.6.1
• System Info: CPU, GPU, RAM, HD:  (Mac Studio)
• CPU: Apple M2 Max
• RAM: 32GB
• Hard Drive: Internal SSD
• Video format: .mp4 8-bit h.264 from GoPro Hero 9,   also with DJI Osmo Pocket 3 - .HEVC 10-bit 4:2:0
• Workflow details: This is with any sequence. Any project on this machine. I’m applying a source footage to a track and an adjustment layer to a track above.  This same process works just fine on my windows PC machine. So this is why I think it’s a bug or a setting that I have not been able to replicate. This problem exists if it’s a Adobe supplied LUT or a custom LUT from a 3rd party.
• Steps to reproduce - Add a source file to track V1. Add an adjustment layer to V2. Open Lumetri color and go to the creative tab. Click the arrows to scroll through lots or select one from the list.
• Expected result - Expected to see a preview of the LUT effect in the Lumetri color panel.
• Actual result -  Lumetri color panel Creative LuT preview window maintains the view of the original clip with no change when you select different ones. (LUT will apply and you can see it in the Program window, but that makes it harder to browse through a series of LUTs to find the look you are looking for.)

PC Preview working correctly

[Motoed-Hidden]

I have a weird bug... I think it's happened before. I have a project and an adjustment layer, I have applied a lumetri effect to the adjustment layer. But when i scroll through selections in the Lumetri panel, it will not preview the effect. If I click on it, it will apply and show in the program window.

If I apply a lumetri creative lut directly to the footage, it will preview, but it will not preview in the adjustment layer. 

I have tried,:

• checking for Global FX mute
• reseting cache and preferences
• restarting app
• restarting Mac
• different projects, same results

This is incredibly frustrating. Attached is a screenshot to show footage, Lumetri panel and program monitor and adjustment layer selected.

I'm using MacOS on a Mac Studio.

Adobe Premiere 24.6.1 (current)

Hello @Motoed-Hidden,

What kind of source footage is it? Is there anything else you can tell us? Is it possible to share the LUT so I can pass it on to the team? Are these LUTs stored properly? See Install custom LUT files.

See also, How do I write a bug report? Let the team know.

Thanks,

Kevin

So it is with all LUTs. Even the Adobe supplied default LUTs.

footage is .mp4 h.264 from a GoPro Hero9

I can confirm later if it works with other footage but Im pretty sure i saw this with otger camera footage.

[R Neil Haugen]

That's actually pretty simple to understand. You are applying that LUT to the Adjustment Layer. NOT the clip.

Adjustment Layers aren't clips.

Ergo, previewing on the AL doesn't work.

Now that Premiere can process multiple layers of Lumetri effects per clip without playback struggling, I rarely apply it via ALs. Nothing useful gained.

Unless applying across say a scene of clips.

[Motoed-Hidden]

This works perfectly on my PC. You can see here... "Source" Adjustment layer.... and in the creative LUT window, it's previewing the SL Blue Ice LUT. 

I feel like I've done this previously on my Mac as well, so I'm a little confused why it isn't doing that when it seems like it should.

Hello!

Thanks for the bug report, @Motoed-Hidden. This is a bug since you used to be able to preview the LUTs applied to an Adjustment Layer in the Lumetri Color panel UI.

Sorry for the frustration. I hope the team will assist you shortly with this issue.

Here is a screenshot from v.15.

Ah Roma!

Thanks,

Kevin

[Motoed-Hidden]

Thank you. I wrote this up and submitted to the bug report forum with the additional detail you linked me to.

I'm having the same issue. I think I updated the latest version and that's what screwed it up—wondering if reverting to a previous version before I updated will fix the issue till the next update. Did you find a fix? 

[ericn46738786]

*update* reverting did not fix it. So what now, do we have to wait for them to find a fix and put it on the new update? it's really slowing down my workflow just researching. 

[Motoed-Hidden]

Yeah, I did not have a resolution for this yet. I have done a number of things with no success including clearing cache, I recently uninstalled and reinstalled all with no success. 

[Motoed-Hidden]

LUTs DO preview when you select the source footage so for now, I'm working out a look on source footage and then save and clear and apply to the adjustment layer... Not ideal, but It's a little better than click to apply to adjustment layer to preview.

I have the same problem. It's very frustrating and slows down the work.

Did you find a fix for this yet? 

[Kevin-Monahan]

Hello @Motoed-Hidden, @r_5205, @mokito98, @R Neil Haugen,

Thanks for your patience while the team works on this bug fix. I suggest turning your attention to the Beta, where a fix might first appear. I'm unaware of the progress on the fix, but I will check on it for you as soon as possible. I apologize for the time this is taking to fx. Take care.

Thanks,
Kevin

As we're under four weeks to MAX, I'm doubtful any major updates for the 24.x series will be released.

I would expect this more likely in the 25.x builds coming soon to a computer near you. Or now, if you also run the public beta versions.

Hi all, i'm kindly asking help from someone.

I'm having issue with the LUT monitor preview on the "Creative" tab on lumetri color; when i create an adjustment layer and put it above a video clip when i try to apply a lut it's not showing on the small preview screen on the "creative" tab.

This is driving me crazy cause i have to check all the luts manually one by one.

I've never had this issue, can anyone help me with it?
in the file you can see the behaviour.

[jamieclarke]

Hi @Tommaso27429828nn3v - I believe the preview section in the creative look has always been a preview of the original file.  Even if you put an adjustment layer above your media, your preview will still be from the original file. 

[Tommaso27429828nn3v]

Hi Jamie!

I have a video I just made showing that in premiere pro 2023 it work with no issue at all but is too big to post, i'll do it again latter

[Ann Bens]

A lut on the original file will show in the creative preview,

a lut on an adjustment layer will not.

2024.6.1

Beta 2025.1 will show preview on both original file and adjustment layer.

[Tommaso27429828nn3v]

But Whi This was working on premiere pro 2023? Is it a bug?

[Tommaso27429828nn3v]

i just tested it and again it's not working.

[Ann Bens]

Just check: 2023 both show preview.

So yes you could call it a bug.

[Tommaso27429828nn3v]

thanks for checking. this is driving me crazy actually, and i can't understands why they didn't fix it already.

[Tommaso27429828nn3v]

but is it working for you on premiere beta 25.1? i just downloaded it and still is not working

[jamieclarke]

HI @Tommaso27429828nn3v - I see this behavior that you are describing, I will get this filed.  Thank you for reporting.
