Moved Media Cache folders, now every clip is unrendered (red)

Hi everyone !

I try everything I could think of with no sucess.

My Premiere Pro cache folders were taking too much OS disk space so I moved them to an other SSD by going to preferences > Media Cache > change path

I moved the content, didn't deleted it. Did it for bith the cache files and cache database.

But now every clip that was showing up as Yellow is now Red so the playback is very laggy.

Before I would create a sequence from a clip, then every clip would show added to it as Yellow, even once I started working on the Motion and the Lumetri -adding Luts etc) and the playback would be smooth.

Now everything is in Red, I tried rendering my sequence so everything turned green, but everytime I change a cut (like extending a clip by a couple of seconds) or change the Lumetri settings, it becomes Red and laggy again.

To see how far the problem extended, I tried creating a new project, importing a clip, creating a sequence from it. It shows up as yellow but turns red as soon as I make a little change on the Lumetri.

Anyone has a solution or workaround ?

I am working with sony a7s II 4K files and add LUTs everytime

Thank you very much.

Huh. Weird, right?

Ok I seem to have resolved it.

There wasn't any problem with the cache files but somehow changing the location made the projects go from GPU/Cuda by default to CPU only, explaining the red instead of yellow laggy playback.

Is that SSD internal or external?

Separately, I would note those files are a right pain for the CPU to use, long-GOP interframe stuff. Really tax the CPU/RAM/threads/cores subsystems. Without a machine really built for those, using the included proxy presets (small-ish Cineform preset is best option) and moving the "Toggle Proxies" control icon onto the Program monitor window is a good option. Proxies on, the icon is blue; off, the icon is gray and you're seeing the original media.

Hi thanks for the help.

Internal SSD.

I understand the compressed sony files aren't ideal for editing, but my computer (built it for editing) was playing them fine until I moved the cache folders.

Tried the proxie idea but it doesn't seem to increased smoothness of the playback.

Thanks Neil,

I came across an interresting problem.

I followed your advice and deleted the content of those folders (then emptied the bin all while Premiere was closed) :

Media Cache

Media Cache Files

Peak Files

I then created a new project, imported one clip, made a sequence out of it, changed some settings (sequence ratio and Lumetrie), saved and quit premiere.

For the old Folder in the OS Disk :

     Media Cache : empty

     Media Cache Files : now contains 4 .ims files [2 appeared when when I opened Premiere, 2 when I imported the clip]

     Peak Files : empty

For the new location on the second SSD Disk :

     Media Cache : now contains one .mcdb file [appeared when I imported the clip]

     Media Cache Files : now contains one .prmdc2 file [appeared when I created the new Project]

     Peak Files : now contains one .pek file nested in a dated folder [appeared when I imported the clip]

So the old path is still being used partly.
