Lumetri Effect Loses It's Mind

[vanlazarus2013]

As I edit, the Lumetri effect applied in an adjustment layer (to make RedLogFilm video have a more final grade), sometimes loses it's mind and makes the colors of the video extremely cosmic.... kind of like it's being applied twice.  This comes and goes with no pattern I can discern.  Seems like a major impediment to using Premiere for any grading.

Anyone know why this is and if there's a way to stop it?

Have not experienced this. Out of curiosity are you using a Master Clip control on these clips?

You can also grade one clip, select/copy attributes then select all other similar clips and right-cick/apply attributes.

Oh ... another question  ... is this during playback or also in exports?

I change the Master Red Settings of these clips, but the lumetri effect is applied on an adjustment layer over the top of my sequence.

I don't think it happens in the render, only preview.... but I'll confirm tonight.

Sounds like a display driver issue.

[vanlazarus2013]

Yes, it's probably related to the display driver....not bugs in the display driver, but Premiere's inability to manage and interact with it.  Other applications seem to play well with the display drivers.   Premiere, not so much.

Still getting random export crashes.  Best practice seems to be to queue exports in AME, save the queue, then close both Premiere and AME for 'fresh start' with the GPU.  Then open AME and start the queue.  Doing anything in Premiere with AME open usually gets AME to an unusable render state more often.  I still get these export crashes when exported directly from Premiere, so it's not only an AME issue.

I've confirmed that this Lumetri bug does reach exports.  There is no pattern that I can see.  Sometimes Premiere behaves well, other times not.

If you use Lumetri directly on the clips rather than through an AL, do you have the problem?
