Lumetri colour gone
Hi guys ,
I have a 2 minute video edited and graded on premiere pro. Had around 2TB of 4K Footage, so created proxies to edit, and once locked relinked to original 4K footage and graded the film. Everything was alright until i moved my 4K footage to another drive( Network drive) from external HDD and re link the footage, simultaneously i updated my premier pro too.
Now the issues is when i open the final sequence the colors are completely off, like Log C, but the colors are just fine in the back ups of the same sequence. Don’t know, its happened because i moved the footage or updated the premiere? I opened the project and relinked only after the update, so not sure where and when its gone wrong.
And if i render the back up sequence the colors go off again. Even when i match frame its shows the graded footage on source monitor. I didn’t use any LUT. Even i tried to switch off/on my lumetri grade but there is no difference. But in reality i graded a LOG C footage. Don’t know what is happening. Any help will be highly appreciated.
* Am using Premier Pro 14.0.0.0(Build 572) and my OS is High Sierra version 10.13.6
Thanks

Below the step by step process i have gone through.
1. 4K footage> converted to proxies> edit locked
2. Locked sequence linked back to original 4K( Log C footage and graded with Lumetri without any LUT> output.
3. Took a back up the 4K footage (only the clips i used) to my network drive/server
I didn’t open the project to check everything ok (my bad )
After 4 months…
Client asked to make few changes to the video, opened the project and i found out the colour are gone. Though the Lumetri effect is still on the clips, its not showing the grade, its just showing me LOG C footage. Proxies to 4K re link is working just fine, but the grade is not there. I tried the external HDD and tried project from auto save, Tried switching global fx button, switched the render engines, checked the display colour management.
but nothing seems to work.Thanks

I’m not sure if this is helpful to your situation but I found, yesterday, that my Lumetri Colors were switching on/off seemingly at random until I discovered that the two places it was happening were places where I had a title above it (actually it think it was happening in the space between two title segments above it) anyway, the only work around I found was to make an adjustment layer and place Lumetri Color effect in an adjustment layer directly above the clip I was wanting to effect. It’s an unbelievably frustrating BUG .

Hi Rob,
Thanks a lot for the reply. I found some serious bug of premiere pro. I did the whole grade accessing the 4K footage from an external HDD. Once the project over i moved the clips to my network drive/server as back up. Next time i opened project, i linked all the footage to the server and found the grade is gone. I reconnected my external HDD yesterday and surprisingly the grade is back, But as soon as eject the external HDD the grade is gone. I reconnected my external drive and grade is back. Surprisingly all the footage still linked to my server/network drive and all the render files, preview files are in the network drive nothing is in the external drive except the footage. Don’t know what kind of bug is this.
Best regards

If this footage is from ARRI Alexa, then that’s been an ongoing problem with Premiere for a few years now. Basically it “forgets’ the embedded LUT. The simplest – though time-consuming – solution is to disable master clips effects for all footage. Then in your sequence, go clip-by-clip and apply the Arri LogC-to-Rec709 LUT for each clip in the Lumetri – Basic tab.

“Premier Pro 14.0.0.0″
My guess is that’s your problem. No x.x.0 version of Pr has been bug-free or reliable, in my experience. I tried 13.0.0 for a while, and many of my Lumetri Color settings would shift upon reopening projects.
I’m still on 12.1.2, because it’s solid, and discovered to my horror that Adobe took that build off the list of legacy versions in the CC installer app, and if it becomes corrupted, I’m going to be forced to using a more buggy version.
You may find this unsatisfactory, but perhaps you’d be better off using Colorista IV.
