Rendered areas in my timeline disappear after a while. It turns red or yellow. I just started experiencing this. My computer is M1 Max 32C 32 Ram 1 TB SSD 16" Macbook Pro. The footages I use are Sony A7IV 4K 25fps 4:2:2 10 bit XAVC S codec 140mbps
First of all thank you Kevin, Hi 🙂 Yes I was using version 23. I had the same problem when I later tried it with version 22.6. I'm using MacOs Ventura 13.0.1. And no, I don't need to turn off the computer. Put Premier Pro in the background. I do a little research in my web browser and come back and they are gone. I haven't changed the video preview codec in the Sequence Settings in my life. I always create the sequence with my main video. I think Premiere does ProRes 422 LT as a default.
Any idea what is goong on with this? I have a 90 mins timeline, all proxied. I render it, save the project and close out, reopen, and something like a third of the timeline has gone from green to yellow and needs to be rendered again? This is v23, on macOS 12.6.1.
Just an update on this - today I reopened a project in which I had carefully spent last week entirely rendering every timeline, and all renders had disappeared. So tonight I'm having to re-render multiple 90 min timelines again.
I left my computer rendering everh sequence in a project overnight - took maybe 3-4 hours or something. Came in this morning, all timelines greem. Saved project, closed project, reopened project (did not quit PP), and all timelines are unrendered again (yellow).
Moved the entire Production to a Mac Studio, rendered everything, and a day later most of the renders have disappeared. So it's not architecture based.
Sorry. Are video preview files on an external drive? A NAS? Any details on the disk you render to? If nothing is unusual, try changing the video preview codec to ProRes 422. Any change?
Hopefully, I can get the product team to weigh in.
I'm wondering if the issue is the external raid... Can you check to see if the preview files are actually still on the raid? They should exist in the folder you've set up in your project settings scratch disk... Also, you might double check that the permissions for that folder are correct... How is the raid formatted? Maybe, as a troubleshooting step, try changing the scratch disk for video previews to the internal raid see if that solves the problem.
RAID is a Thunderbay4 SoftRAID, formatted MacOS Journaled. Permissions are set to be ignored on the RAID. Both Previews folders have lots of render files, as expected, and there's 20TB free on the RAID.
Just this very moment, I spent 20 mins rendering the entire film - all green, fully rendered. Save All, then Quit. Without doing a single other thing, I immediately reopened the same project, and 1300 previews have disappeared and need rendering.
My understanding is that software raids are less dependable than hardware raids, bwdik. strongly suggest you try rendering to a non raid to see if that solves the problem. If it does, then we can try and figure out what's going on...
I had initally been rendering to a single drive SSD, but that had exactly the same problems. I guess I can dig out another Thunderbolt drive and try that.
All my project files are located on the internal ssd of the Macbook. I have been advancing with the same working principles for years and this problem has existed for 2 months.
