Losing render files

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?

I'm still on 25.2.3 but this losing Pro Res files is still here after several years

I have recently submitted a Premiere project to Adobe Dev Team where I had Transition overlays on cuts.

Some of the ProRes previews generated by these transitions in ProRes were randomly lost.

Normally after closing and re-opening project (as usual)

I await Adobe input on this as not heard anything yet.

Hi @Peter Reef

Can you outline type of media and circumstances in which you are losing Pro Res Previews?

If we can get some common idea on reproducing the problem reguarly we can feed this to Adobe Team .

thanks for your help @JonesVid. i am working on a 30 min documentary with 50p UHD footag from Sony FX3 - mostly XAVC-HS. As its taxing the system I am mostly working with proxy files - prores proxy in UHD. Especially when restarting premiere or reopening the project this happens. Not all Render files are lost but suddenly there are a lot of yellow or red parts in the green timeline. I am working with adjustment layers for CC, sharpening Video filter, those are always locked and the lost files are not restrickted to a certain adjustment layer area.

Same issue here. I am constantly loosing some render files. not all but some on the latest version 25.3.0. I disabled it to open the last timeline when opening the project, still the same. Rendering some effects takes ages, does anybody know a workaround?

Is anyone on this thread still losing Rendered files - as of Premiere 23.5 version ?.

I have a major issue with 4K Pro Res rendered files being lost.

See my post in bugs : https://community.adobe.com/t5/premiere-pro-bugs/some-prores-422-video-preview-files-lost-on-closing-and-re-opening-project/idc-p/14039263#M13988

If anyone has any info to help avoid losing rendered files let me know.

The files are in my project folder on an internal fast NVMe drive.

Media Cache is on a different internal NVMe drive as well. (Not System C:)

Appreciate any info as I have radio silence from Adobe.

The problem occurs on my older separate Intel 9900K machine as well. Similar setup.

Thanks

With Release of update 24.1 I have been losing render files gonig from green to yellow after restarting. This last time when I came back to the computer premiere lost the pathway to the original location of source files and when I reconnected the video clips the render files have not come back.

I'm guessing but ..... I am convinced this is a bug to do with database of rendered files getting corrupted/shifted after close down and start up.

Eveything is fine when live in memory but close down project and start up loses all thoses indexes ?.

Having the same problem. V23.3 and PP just seems to randomly forget all the render files after a day or two, sometimes after just closing adn opeing it. Also I have one complex project that takes minutes after openng to find the render files when they do wotk. They are stored on an external drive within the project foldres.

They are stored on an external drive within the project foldres.

By @James5FC9

Does the external drive have a setting that allows it to sleep? That could be the issue.

If that's not it, try a different cable or port to the drive.

Different cables have been used, and it doesn't seem to have anything to do with the drive going to sleep or not. Yesterday I checked that the project was rendered, closed PP and unhooked the drive and then this morning first thing I plugged the drive in, launched the project and render files lost.

Is there a solution to this issue? I have worked on several versions of Premiere Pro on Window and Mac, now on Mac in 2022 version. Why do we lose connection to the render files???? I can have 2 timelines open, render sequence 1, switch to sequence 2 and then switch back to sequence 1 - the red lines are back. I have the render folder with the project on an fast external SSD. Otherwise the internal drive fills up, especailly as I need to re-render everytime I switch to export another sequence. Please advise or fix this.

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.

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
