Premiere Pro randomly adding contrast to some clips on import

[leiga]

I've seen several threads with what seems to be the exact same issue but none of the solutions have worked for me. What's most bizarre is that it's not even all the clips, it's about half. Contrast is being applied on some takes and not others of the same shot. The original footage is log and looks normal when viewed outside of premiere pro. Even the footage transcoded with media encoder looks like the original log footage.

I tried exporting a clip with original color together with a clip with the added high contrast and the high contrast is still there on the 2nd clip on export so this is clearly not a monitor issue. It's a premiere pro issue.

Footage shot on Arri Amira in 4k.

I've tried relinking, updating and restarting premiere pro, switching off "Enable Color Display Management", turning off "Enable hardware accelerated decoding", and Profile First Aid in ColorSync Utility.

That looks like typical log footage in one shot, normalized in the other.

Have you checked the Source tab settings in the ECP with a clip on the timline, to see if the Arri-raw controls are being used?

They aren't being used. All I've done so far is import and transcode the footage.

[R Neil Haugen]

Do you mean you haven't used them, or that they aren't appearing to be used in the ECP?

Both, I haven't used them and I checked the ECP to be sure.

Any way you could get me a sample clip of those in the original media? I'd love to test that next week and see what's going on.

I found the solution: https://community.adobe.com/t5/premiere-pro-discussions/disable-auto-lut-on-import-of-amira-log-foot...

Premiere Pro was auto-applying a lut on import. As for why this lut was only applied to some clips and not all. I still don't know.
