Save thumbnails cache for project panel thumbnail view

Thumbnail cach is absolutely killing my vibe. In the timeline as well. Everything is proxy. Can barely scroll anywhere without it all grinding to a halt.

Using a codec like ProRes can be good for any workflow, but it's not a replacement for a thumbnail cache.

I agree Adobe needs a real fix for this in the code. This issue cost me literally weeks of time. But at least by switching to Prores it is now possible to work. Whether you call it a solution or a workaround, hopefully this can help others to at least get back to work. If someone had told me it would have saved a lot of wasted experimentation.

My feeling is that Adobe should stress the importance of using efficient codecs- some kind of disclaimer or notice during install. It has made a difference in so many areas- plugins process better/faster, and I'm experiencing 99% less crashing since I made the switch to working this way. The system now feels like it is running properly. So I would suggest for those still working with long-GOP codecs it is worth converting your clips to Prores.

I have the same problem and I fix it by using old codec pack, Try this it might works with you as well. The version I used it this ""K-Lite_Codec_Pack_1190_Full""

I agree with Alex. Workarounds are not a solution. Fixing this should be at the very top of Adobe's To Do list.

Dan, that's not a solution. It's a workaround.

A solution would simply be - as requested - to save the thumbnail cache.

It's not a revelation that ProRes generally performs better than Long-GOP codecs. We know this already.

I have found a solution for this. Others have mentioned this but it seems to be getting missed in the thread. I ended up converting all video clips to prores and the problem disappeared. The problem is due to codecs such as H.264 being much slower to process. If you use Prores or Cineform the thumbnails will appear almost as quickly as you scroll. Prores is generally better to work with and I find less crashing with plugins as well. There should be a big disclaimer by Adobe and this should be considered essential knowledge for anyone using Premiere. I had to figure it out myself but now I am able to edit my documentary.

It is extremely frustrating and kills my workflow. I hope there is a solutionsoon

We think of this problem as one thing: slow thumbnail loading, and that's pretty good summary but there are two things going on...

#1 is the the transient, must-scroll-to-load nature of thumbnails in ppro. In my opinion, it's the crux of the problem. This is compounded by issue #2, which is that some codecs load extremely slowly.

Proxies only address #2, but they do mask #1 (thus the overall slowness) to the point where it may not be a problem in practice.

What we experience is that a thumbnail will not load unless it is in view. So in a bin with hundreds of clips only the first dozen or so in view get loaded. Then you scroll, then you wait. Proxies or "faster" codecs to begin with just make the wait time less.

If thumbs always loaded lightning fast, I suppose their current load-when-viewed algorithm would be ok. But the combination of these two issues is obviously not working and some codecs will probably always load somewhat slowly. Which is surely why other software opts for caching thumbs (you only have to look next door at lightroom). That said, Resolve does not cache thumbs (right?) and they've made the thumbnail experience much less painful.

And btw if you happen close a bin, you might have to start the scroll, load, scroll, load process over. So, in addition to using proxies for slow codecs, I also keep many of my most-used bins open in different tabs. This keeps them open and active and the thumbnails loaded. And I rarely close a project once open for this and other reasons (media load time when opening a project is another topic I could rant about).

But yea, this is all really really dumb and the fact that Adobe doesn't appear to give a sh*t about this and a bunch of other no-brainer productivity-killing bugs is making me transition away from their software as much as I can.

I have to get back on what I said about the solution of Andy, I didn't "enable proxies" in the preferences -> media options yet. Apparently this option is disabled by default. Since the enabling, loading of the thumbnails is almost immediately. So what I did is make proxies of my GH5, h.246 footage in 'prores medium resolution proxies'. And it works like a charm now. Disappointing though that I first have to transcode my Panasonic GH5-footage before editing (which also consumes quite some disk space), but I am happy using proxies speeds up the thumbnail loading drastically. I hope in the future Adobe can speed up H.246 thumbnails.
