Missing Custom LUT

The LUT's in the wrong place. When it's used by Custom LUT it's stored in the user Library/Application Support/ProApps/Custom LUTs. If you use the menu for the offline LUT and select Reveal in Finder it will show you the file path to where it should be.

I tested it again like this. I put a library with external media in a folder on an external drive. It had a project with a dozen clips, each with a Custom LUT effect with a separate LUT. I copied the Custom LUTs folder from ProApps into the folder with the library. I took the drive to another machine, opened the library, and reconnected the media. All the project clips had Missing LUTs icons. I put the contents of the Custom LUTs folder from the external drive into the Custom LUTs folder in ProApps in the user Library of the new computer. When I switched back to FCP all the project clips were populated with the correct applied LUTs.

Can you post a similar screenshot in Column View showing the LUT in their expected location, under /Library/Application Support...?

And also, just in case, remove them from under Motion Templates. If you are fearful of doing it, just temporarily drag that "Alister..." folder to the desktop, and start FCP. You can put it back later, if you want.

The LUTs should not be there. I don’t care what the creator says. They are not Motion effects or anything at all to do with Motion templates.

What’s in ProApps/Custom LUTs?

In the effect that has the missing LUT, if you use Reveal in Finder it should take you to the Custom LUTs folder. If the LUT is there and it’s not using it I don’t know what the problem as I can’t reproduce it across multiple systems.

Can you post a screenshot of the LUT in the Custom LUTs folder filepath in column view. I don't think think the LUT should be inside Motion Templates/Effects. It's not a Motion effect.

Also a screenshot of the Video inspector with the effect.

What happens if you point the effect to the LUT, does it relink?

Your first message says they’re in the Movies folder. That’s not the correct location for an applied LUT.

My cookbook memo for the FCP LUTs. I guess it should then work with different Macs?

- LUT for the project:

[select a clip in the timeline] > Window > Show in Workspace > Inspector [cmd-4] > Show Info Inspector [i at the upper right Info Inspector] > General/Extended/Settings [at the lower right] > Camera LUT > [at middle right] Add/Select Custom Camera LUT... > [select LUT(s)]

- LUT for a clip with Mix 0-1:

Window > Show in Workspace > Effects [cmd-5] > Custom LUT [drag to clip]

Window > Show in Workspace > Inspector [cmd-4] > Show Video Inspector [film strip at the upper right] > Custom LUT [at upper right] > Choose/Select Custom LUT... > [select LUT(s)]

To remove imported LUT from the pop-up menu, choose Reveal in Finder and drag the LUT files to the Trash, and reopen Final Cut Pro.

~/Library/Application Support/ProApps is then something like this:

Just tried it. Put the LUT in the folder, and it immediately populated in the library.
