Weird ghost overlay when adding LUT on Premiere pro

Report · Oct 19, 2020

Hello,

I'm using Premiere Pro on a Macbook. I'm in the end of editing a project, and when applying luts something extremely weird happens. Basically I have two videos: video A and video B. In my timeline, they are placed like this: AB, no transition, just a cut. When I apply a LUT to B, the shape of A appears like a grey overlay (only while playing the render and exporting).

Attached you can see the frame A, with big mountains, and you can see the frame B, with this weird grey shape, which is the exact same shape as the mountains in A.

Theses stains are also visible when exporting, which is a pain in the ass. I dont know what to do.

After messing around, it appears that the overlay only appear when I apply the LUT in the creative tab, not in the Base corrections tab. Any ideas why?
