Hi everyone,
Our latest version of Influx Importer https://www.autokroma.com/Influx
caches decoded thumbnails, It would be great if you could test it and give us your feedback !

There is a free demo where this feature works for free ! By default it'll only work for new extensions and codecs. But you could turn "override adobe" checkbox in the settings of Influx temporarily just to test this feature and see if we can improve on Adobe Premiere Pro behavior

On my Windows PC, this issue was annoying but now on my 16" M1 Max MacBook Pro, it's downright aggravating. While editing, the thumbnails in my timeline often disappear completely and then quickly start redrawing one by one, slowing everything down, before disappearing again and redrawing in a constant loop, 3-5 times before the nonsense ends. Once this bug begins, it seems to keep happening until I reopen my project. Anyone else seeing this problem on a MacBook? It never happened on my Windows computer or on my 13.3" M1 MacBook Pro but that could simply be due to the fact I used prior versions on Pr on that MacBook.

Been having this problem for a year now. I've tried everything (M2 SSD, proxies, cache clear and location, etc). I've made the decision to switch to DaVinci. This, crashing, and export bugs were bad enough to where I'm willing to learn a new application and lose a few features.

To follow up -- noting that for me, my cache folder had erroneously been reset to the project folder I guess after a PPRo update, and not the cache folder on my SSD. After updating that, the issue appears to be better. Another difference between systems is the i9 is running Windows 10, this one is running Windows 11 and running McAffee (have to for work)

Funny, on my system with 32GB ram, 8 core i9, and a Geforce2070, this was no issue. But when I moved to an AMD Ryzen 9 5950X 16 core with 128GB ram and a RTX 3090, suddenly I'm having this issue and it's the worst. In case that data helps the issue.

Thanks for all the information people. Seems like it's a complicated topic, let me ask one (hopefully) last question : as I see there are three places where the thumbnails could be constantly regenerated :

* 1) Project Panel Bin with imported files
* 2) Media Browser
* 3) Timeline

Pierre-Louis Baranek when you mean a "bin" you're talking about 1), correct ? Otherwise, would a folder in the media browser also display this annoying bug of regeneration ? We can replicate some of the behavior sometimes, but not all the time, so the more info to clear up the situation, the better

Thanks everyone
Antoine

Takes around 30 to 45 seconds for the first 9 thumbnails in the view. If I expand the window, it takes close to 1 minute or 2 for 25 clips to generate a thumbnail.

Thanks Sunny and Pierre-Louis for the info. Once you scroll to the first batch of clips without thumbnails, how fast are the thumbnails generated for those clips ?

Hi Antoine, the number of files in a bin makes no difference whatsoever in the processing of thumbnails as far as I can tell since whether you have 50 or 500, it will only generate thumbnails for the 20 or so files that are currently in view. Even if you open a bin, take a 30 minute break and come back, none of the files that are out of view will have a thumbnail. They'll get generated only once they're scrolled into view. This design is complete insanity and part of the reason I'm so annoyed with the Pr team for spending so many resources on interface redesigns that are of little help (ie. New import/output pages) while continuing to neglect massive problems like this one. A lot of people talk about background rendering. How about that rendering include thumbnails too?! Render files don't disappear every time you reopen a project, so why should thumbnails?! Adobe's silence on this issue is quite telling.

Close to 15 files per bin. But the problem persists even if I have just 2 or 3 files. 1 file maybe doesn't take that long but still... It's still more than a second.

Hi everyone,
Could you confirm the amount of files per Bin/folder you have when it takes a lot of time to regenerate ?
Thanks

Adobe team. I'm running i9 12900k and 3090Ti on an SSD. It is ridiculous that I'll have to wait for footage thumbnails to generate every time. I mean... Why? Please fix! What good are system upgrades when a small thing can just render all that null.

Thanks for the video Luke. I can see two issues : first indeed the thumbnails are not cached, leading to constant regeneration. Second, some video files can be very slow to open and create the first thumbnails, slowing down even more the first issue. We'll study that more in depth

I've just pressed the button, give it 20 mins https://youtu.be/0amCKcKB5dU . For the benefit of Adobe Dev this is the issue in effect.
Reminder: AMD Ryzen 5 1600X Six-Core Processor @ 3.60 GHz , 16GB RAM, GTX 1060 6GB. SSDs.

Afternoon all, just screen capped a video of this happening. Will upload in a bit. Wheres the dude asking for recreating the issue I saw post?

Ok, I'm sorry that I misunderstood this topic.

It's not the same because for it to work in the timeline you'd need Premiere to generate a thumbnail for every frame - that is what a proxy essentially is.

@Alex Elkins Yeah you're right, but isn't it related. If there is going te be a cache for the project panel. Couldnt this also solve this issue in the timeline?

Thanks Boy, We don't see the bottom and right of the screen but yeah you're also talking about real video decoding here

@Boy Linders - Your video just shows that computers struggle to decode Long GOP video - no real surprises there and it's why you use proxies.

The feature request relates to the need for project panel thumbnails to be saved to disk so that Premiere doesn't re-generate them in RAM every time a bin is opened.
