Applying Correction LUTs (as presets) almost works

njandersen

Description

I want to be able to apply different correction LUTs to different clips quickly.
LUTs currently have to be saved as a "video preset" to apply to multiple clips/sources at once, and to be able to add a keyboard shortcut that adds the videopreset/LUT.

Expected Behavior

The preset is simply adding a "lumetri color" effect to the clip, with a correction lut (example: C-log3 to rec709 conversion) in the Basic Correction panel of Lumetri.
To apply this quickly, i use excaliburs search or excaliburs keyboard shortcut for this preset.

Actual Behavior

The preset is applied, but the lut selected, instead of being "clog3 to 709" says "custom" with no change to the image.

Applying the videopreset that contains a correction lut works as expected in premiere when applied normally by dragging and dropping, but not when applied through Excalibur.

Steps to Reproduce

Apply lumetri color to a clip
add a custom lut in the "basic correction" input lut
In effect controls, right click the lumetri effect and select "save preset" with any name
Go to the timeline and select any clip
in excalibur, search for the preset and apply to the clip

Context

I'm trying to make a color correction workflow that is super fast. Doing this without excalibur is possible, by adding a correction lut to multiple clips in the project panel or timeline, but this is not good for clips that are under/over exposed and need an adjusted lut to look normal (+0 +1 +2 and -1 -2 EV exposure luts, etc)

Things i tried:

different luts
lut being applied to "creative lut" in lumetri instead

Your Environment
The custom luts are added to this path, so the luts show up in premiere
/Library/Application Support/Adobe/Common/LUTs/Technical
I didnt have luck with built-in luts either

Excalibur version: 1.1.4
Premiere Pro version: 22.0
Operating System and version: M1 Macbook Air 2020 with Monterey 12.0.1

Got your idea, I will check it!

Sir_Ivan

Did you try with basic LUTs?

Those one seem to work. Custom/Browse apparently fall under API limitation (no way to use them).

EDIT: don't use location mentioned here, use another one in comment below.
Though there is a hack how to add custom LUT to default list (see SL GOLD HEAT at the bottom?).
I went here (needed to use "show contents"):
/Applications/Adobe Premiere Pro 2021/Adobe Premiere Pro 2021.app/Contents/Lumetri/LUTs/Technical
And added LUT I needed, after that used it in Lumetri effect, saved preset and it works.

Ok, I've checked this video:

and yes, you can put LUTs here, no need to use hack above

Sir_Ivan Thanks for the help!

Solved!
Tl;dr For my M1 Mac Monterey system in Premiere 22, the luts will only apply with a preset (applied with excalibur) if located in one of these folders:
Technical luts:
/Applications/Adobe Premiere Pro 2022/Adobe Premiere Pro 2022.app/Contents/Lumetri/LUTs/Technical
Creative luts:
/Applications/Adobe Premiere Pro 2022/Adobe Premiere Pro 2022.app/Contents/Lumetri/LUTs/Creative

Luts found here will show up in Lumetri Colors "Basic" and "creative" tab, and can be used for presets.

Long solution:
There are 2 locations to put your luts, both locations let your LUTs show as built-in in the drop down selection, in lumetri color in premiere.
The location below is, i believe, more universal and accessible by other users, and all different versions of premiere.
/Library/Application Support/Adobe/Common/LUTs/Technical
The problem is that, for my system, they would not work when applied through a preset activated by excalibur.
The preset itself would work, but when applied with Excalibur, it would not work. (it just shows "custom" lut has been applied, but nothing has happened.)

For my system, the luts found in the other folder, path below, do work with excalibur. Maybe its due to accessibility/safety settings in mac, m1, Monterey, or Premiere/Excalibur or whatever, it does work as expected. But note that every new Major premiere version you might have to move this entire folder of luts to the new path for them to show up in lumetris dropdown. This also might make the luts not visible by other mac users on your computer?
/Applications/Adobe Premiere Pro 2022/Adobe Premiere Pro 2022.app/Contents/Lumetri/LUTs/Technical

Thanks again Sir Ivan for the fantastic tool, and your ongoing support and improvement of it.

njandersen thanks for testing!
I also made my tests with API and it looks like I will be able to fix the code so you can put LUTs in official place, not inside app itself.
I even think I can use Custom LUTs now as well, so no need to put them in special folder.

Will fix it in next update.
