Colour Grade Changing while playing or scrubbing footage

Hi all,

 

I've got a weird problem hapening in Premiere version 23.0.0 (Build 63)

Computer is a PC


Processor 12th Gen Intel(R) Core(TM) i9-12900KS 3.40 GHz
Installed RAM 64.0 GB
Nvidia 3080 Card

 

Colour grading SLog 3 footage, whenever I scrub the timeline or press play, the grade changes. Scopes shift and everything gains contrast and saturation.

 

I've tried removing media cache files, restarting, using a different grade (tried with and without a LUT) but no fix as of yet. Some files have proxies which are turned off, others don't and both seem to be having the issue.

 

First frame is the playhead not moving.

Second shot is the playhead scrubbing

The IRE vlaues shift as does the playback image leading to one very confused grade.

 

Any fixes or advice would be appreciated.

 

JK

Hi JK, 

Getting more information about this would be helpful. Please take a look at the How do I write a bug report? post and follow the suggestions there. (In this case, particularly regarding the video format you're using.)

Thanks,

Fergus

I can't see the actual reply here on the forum but the drama seems to be in the playback resolution scaling. Some helpful soul solved it.

It was scaled to half and the adaptive resolution was causing colour shift and exposure drop.


A bit more information about the project:
Video codec: Video Codec Type: MP4/MOV H.264 10 bit 4:2:2

Single cam seqence REC.709 4096x1716

 

Issue seems to start after turning the playback resolution scale on and playing the clips had the same issue.

No difference if the clip had a lumetri effect or  not.

 

Turning the scaling back to full resolved the issue.
