LOSING RENDER FILES!!!!!!!!!!
I DON'T KNOW WHAT WE HAVE TO DO TO GET YOUR ATTENTION ON THIS, BUT WE'VE BEEN COMPLAINING ABOUT THIS FOR YEARS. I'VE BEEN PERSONALLY COMPLAINING ABOUT THIS FOR MONTHS. IT'S A SERIOUSLY PROBLEMATIC ISSUE THAT REALLY IMPACTS MY WORKFLOW. FIX IT AS SOON AS HUMANLY POSSIBLE, PLEASE! PLEASE IMPLORE UPON EVERYBODY WHO IS RESPONSIBLE FOR FIXING BUGS THAT THIS IS THE TOP PRIORITY TO FIX!!!!!

But hey... Billie Eilish uses Premiere Pro so who cares if this gets fixed.

I have this problem a lot. It happens if for me when I'm dynamically linked to a complex AE file with multiple expressions. Whenever I close or open the AEP project file premiere will trigger a "conforming proejct.aep" step and conform the audio and then everything goes offline....
So here is a typical scenario for me....
1. Timeline with many dynamic links. Projects that have multiple expressions or an effect like plexus seems to trigger this problem most frequently for me.
2. Render the timeline. (Premiere fires up a BG AfterFX.exe)
3. Decide you need to open the after effects file for any reason
4. Even before you touch a single comp or parameter, premiere will trigger a reconform (bottom right corner progress bar) and all of your rendered comps go offline.
A few theories....
For complicated comps there is some mismatch between rendering with the background Render and keeping AE open while rendering in premiere. Sometimes if I render something, open AE and all render files go offline, but if I then keep premiere open and then close the foreground AE, the render files will then to return to green. It seems to me that there is some bug in dynamic link that is causing this problem.
Its a real headache and projects with dynamic link are now a plague. I try to render out as many things as possible to disk as the dream of dynamic link being an effective workflow is now basically dead and a waste of time. One of Adobe's killer features has been basically a boat anchor for a couple of years now and its sad.
I'm not sure Adobe knows how frustrated its customer base is with their progress in improving their software. Every editor I talk to has nothing nice to say about the state of the software. So many people are jumping ship to Resolve or FCPX. Those of us who haven't yet would gladly just ditch if we weren't locked into 10 years of project files and that we still need to open and the apparent lack of innovation in the motion graphics space giving us a viable option to AE. Adobe is very lucky that Fusion is a no go for motion graphics.
Just tried to see if new version 14.6 of Premiere Pro fixes this 'Lost Preview Files' issue - but doesn't.
When using Quicktime based preview files (I'm using Apple Pro Res 422 files) they somehow get lost - plus looking at the file information in the Preview Video files folder reveals that they are there BUT time stamped into the future !. eg Today (24 November) some of my preview files are date stamped December 2nd 2020 ?. Weird.
The Windows 10 Pro operating system is at 1909 version (all Updates installed) and no other software on my machine exhibits such behaviour.
So Adobe team - what is being done to investigate this issue of lost Quicktime preview files?.
So I eventually tried version 14.2 again then to 14.3 on this Rendered Files lost issue with still same problem
I also had a weird problem of all rendered files in the Video Preview Files folder being dated 5 days in the future !!.
I posted something on the Premiere Pro community forum about this see -
Ann Bens said she had seen this issue in some AE cases and thought it was related to QuickTime files only. I see Rasheed is using Pro Res.
Updating to 14.3.1 (and some Windows 10 updates as well to version 1909 ) seems to have made this issue go away....at least the dates for Rendered files are OK now and so far I do not appear to have lost rendered files when re-loading the project, but I am keeping a close watch on this.
I'm editing 150MBs H264 4K 3840x2160p files from my GH5 (no proxies) and the rendered files are Pro Res 422 (not i-Frame MPEG) with plan to make ProRes422 full rendered master from which then to produce various format copies - eg H265 4K etc
Some response from Adobe Engineering on this bug report thread would be useful please. eg: Have they addressed it as enough examples below to try to reproduce it on Quicktime files?

I've just come across this problem as well. I'm in Premiere 14.3.1 on macOS with 32GB RAM.
I'm in a 4k DCI Timeline, 23.967 fps with a I-Frame only MPEG preview files set to 1920x1013. Composite in Linear Color is selected. Footage is 8K RED, using 1080p proxies (ProRes Proxy).
Like the OP's video, I hit render, it renders the frames, the timeline render status bar turns green, but about 2 or 3 seconds later it reverts back to red and the rendered frames are no more.
It does not require a restart of the program to lose these files. It is near-instantaneous after the render is complete.
Steps I've taken, though the problem persists:
- tried render with proxies turned on. tried render with proxies off and original media only (same result)
- deleting unused media cache files
- copied media to new timeline with settings native to the original media
I've just come across this problem. I'm editing in 4K and creating a final Master Pro Res 422 file so all render previews are in Pro Res 422.
I created a folder in Preferences to make sure each Video preview is in he right posiiton. But reading below I see that you should not change default files - which is a bit crazy on Adobe's side as you have an option to create a Custom Location for Rendered files.
I am losing rendered files every time I close project and re-open it.
This is taking ages each time the project opens and is a pain in the xxxx.
I'm using Version 14.1 (not very latest).
Any comments Adobe?

I render my timeline, save it, close the program reopen it and the same project - no render files - need to rerender every time.

I was having this issue and in the end it came down to the fact that i'd broken the adobe dynamic links by moving my Premiere cache. So... I unhooked all of my external drives, restarted Premiere and then chose the default cache settings when it prompted me to do this.
This wasn't the end of it though as it would still lose all of the AE render files when I shut down and then restarted Premiere. So I guess there's more to the dynamic link than we know i.e. once you break the link it not only breaks on the Premiere side but also somehow on the AE side too.
The workaround for this was to open the linked AE files, save them as another version and then import the new version back into Premiere and replace it in my timeline. Once I'd done this I could render the AE comps in Premiere, shut down and restart and low and behold the green line always remained.
I guess the moral of this is never touch the default render files location for Premiere as it's a complete ball ache to get it all working again if you do.

I understand that you are frustrated and angry. To get issues addressed and consequently fixed, we'll need clear steps to reproduce the problem. While I appreciate that getting this to happen may be very obvious to you, it isn't for everyone. I'm not sure that I can recall ever losing a render file while editing unless I changed an effect, effect parameter, transition, transition parameter, replaced media, or added media. If you can help us out with steps, I'll do my best to get the issue addressed.
