Losing render files

[cmacfido]

I am working on a very heavy project with multiple sources, green screen and virual backgrounds.  It took me over five hours to render this thing out and when I shut it down and re-opened it, all my renders were gone. In fact one time I duplicated a sequence and lost half the render files.  I am on Premiere Pro 2020 and this is a major problem.  I have more of the shows comming and if this keeps up I will have to switch to Avid.  Is there anyway to avoid this?

Not to address your exact issue, but I've noticed all red render bar in your project. Check if you can rearrange effects according to this rules, for faster render: https://community.adobe.com/t5/premiere-pro/order-of-filters-effects-and-drop-in-cuda-rendering-spee...

Where are your preview files located?

Are they on an external drive?

[cmacfido]

Yes, they are on a G Drive with athunderbolt connection.

I'm a Windows guy, not a Mac guy, but I suspect that the preview files being on that drive is at least part of the issue.

Hi there, i have been experiencing the same problem. I'm working on a 90 minute documentary with multiple footage on a Full HD timeline in Premiere Pro CC2020. It takes a while to render the whole thing as you can imagine but my timeline eventually turns all green.

If i close Premiere and reopen it, the timeline is back to yellow and i would have to render again.

There's no problem with the render files location (on the same SSD where all my files are) so i don't understand why this is happening.

Did you manage to find a solution? or got any feedback from Adobe regarding this issue?

Cheers,

Phil

I'll echo pretty much everything here. 85-minute documentary and within two days of rendering from beginning to end the render files on my external Thunderbolt 3 drive become unlinked and the green render line is again yellow and red. This has happened about 10 times over the past month. Not an issue to render overnight but I have to explain to the producer in a remote Zoom session why smooth playback is not an option. The Adobe name gets tarnished a little bit each time...I did not have this problem with Avid Media Composer.

I'll expand the topic to workarounds...is there any way to relink the render files to the sequence or restore the folder's relationship with the project or sequence?

I'll also mention that the thunderbolt drive has a touchy power supply, and any turbulence on my bookshelf has the potential to turning it off. I get them started again before I do any operations in the Premiere Pro project, and the link to all of the video and audio files are restored. I haven't observed this to be the moment when Premiere "forgets" where the render files are, but I thought I'd add that observation in case render-file-amnesia is somehow related.

As a former Avid user I'm thinking things like, "2022 and still linking issues, Adobe?" The sparse response to this 2021 thread is also underwhelming.
