red and white checkers where video should be

[ryanhandt]

I'm having a major issue that I cannot figure out. I'm newish to Premiere Pro. I've been working on this video for a while. I've done a bunch of editing and I'm going back in for final tweaks. One issue I ran across was the audio was too low. I sent the audio to Audition and when it came back, I had lost all the video that was connected to the audio. In my timeline it was replaced with red and white checkers:

does anyone know what this is or how to get my video imagery back?

for more info, the clips i used will play in the source window, but not in the timeline, even when i try and replace them.

Thank you

Hi RyanHandt,

Give us full system details, the kind of media you're using, and whether or not you're using any GPU accelerated effects. Also, let us know in Project Settings, if you are using GPU acceleration or Software Only under the Renderer.

Thanks,
Kevin

I'm working on a mac pro. settings below:

the video files were .mov

No GPU accelerated effects i know of. New at video editing. (I think I may have found the root of the issue. I see it under my Lumetri Color preset I made, the same red/white checkers, in a preview.)

I'm using GPU acceleration.

I'd still like to figure out what was going on, but I did find a work around. I had to re-dropin all my clips. I'd double click on them in the timeline and repeal them from the source window. Only issue is I lost all effects i had on them. sharpening, noise, color corrections, etc.

Hi Ryan,

This appears to be caused by applying legacy Luts. I've seen this issue under the follow conditions:

1. User creates an 10.4/11.0 project which has legacy SpeedLooks Lumetri presets applied (i.e. SL Blue Cold (Canon 1D))
2. User copies the project to another OS (Win/Mac)
3. User opens the project in software render mode

Workaround:

Delete Lumetri effects, re-apply preset or just disable.

Can you confirm if you were working with a legacy speedlook lut?

Thanks,

Peter Garaway

HI Ryan

I think it has been mentioned already(deleting the Lumetri effects), also providing you a link to the KB document just in case.
