LUT's issue when importing old project

When I opened an old project of a documentary made with Premiere CC2020, the LUTs that were applied on an adjustment layer are sometimes applied and sometimes not. All thoses shots are using the same LUT. 

This project was initially on another drive, but the entire project folder has been mirrored on the one I'm using.

 

I had to re apply shot by shot the LUT that was sometimes not applied or not correctly apply the LUT.

When importing the LUT in the Lumetri Panel in "Creative" than "Look" -> "Browse", sometimes on certain shots the LUT give a complete different look that it should give. Colors have less contrast, shadows are very light (see the video).

So when I add a new Lumetri color effect in the panel and import the LUT in question, the LUT is imported correctly and the result is as it should be.


Does anyone has an idea how we could open an old file without having to do a part of the grading again and avoid this kind of problem with LUTs?

Thank you 🙂

Hello @simon_hardenne,

Thanks for the bug report. The team may need more information about your system and media in order to reproduce your bug. See: How do I write a bug report?

 

As Neil suggests, the LUTs you originally applied might not have been installed in the proper directory, so when you reopen the project, they are not in the same location.

 

Your source footage could also be related to the problem. We need more details about it. For example, is the footage HDR?

I couldn't tell where the LUTs were saved. Parts of your description are the behaviors expected if the LUTs are added to the folders with the Adobe supplied LUTs. But I can't tell as you don't include that information.

Thank you @R Neil Haugen for your reply. 
Indeed, I forgot to mention that. The LUT in question is located in the project folder, with the same "tree structure" as when it was last saved, on an external SSD.
