Lumetri Color is incredibly slow in After Effects

I am running After Effects on a 16 inch Apple M1 Max Macbook, 32GB ram.

 

AE runs incredibly well on this machine, but by simply applying Lumetri Color to a clip the whole program stalls. If I make any basic tweaks to the effect, even as simple as changing highlights by a few points, it takes minutes for the updates to then reflect in the preview window. 

 

I would normally never grade in AE but I am attempting to do a day to night effect, and right now it's impossible. 

 

Any ideas?

    I've noticed that the issue seems to be fixed if I apply all lumetri effects to an adjustment layer, rather than the actual footage layers - let me know if that works for you!

    EDIT :

    I found a solution for this problem that has been bugging me for months. In the project pannel, if you click on 8bpc you can access the project color management. Switching from Mercury hardware only to GPU seems to fix the issue on my 16 inch Macbook Pro M1 Max.

    Hope it helps.

      Thank you - this solved it for me. I'm also on Macbook Pro M1 Max / AE 2024. Lumetri was bizarrely slow: 1.5 seconds to render a frame for just Lumetri on an adjustment layer.

      Same issue here on 16 inch Apple M1 Max Macbook, 32GB ram. It has been going on for as long as I can remember. I'm now on Sonoma and After Effects 2024 v24.1. It worked fine last week, and now it's back to an excrutiating slow speed whenever I put a Lumetri effect in AE. It works fine in Premiere though.

      I can attest that it is indeed painfully slow to grade with Lumetri color in After Effects, I have to literally leave the main comp rendering overnight as it takes several hours. This is on a maxed out M1 Macbook Pro 16.

        it didn't work with my comp, simple color correction with lumetri color effect, epic rendering times. I don't understand why.
