Cache problems with large projects

Jun 21, 2012 6:44 AM

I'm once again having a nightmare with the media cache files generated by Premiere on my Mac. The project I'm working on has 1,250 Canon C300 clips and from thiose premiere creates around 15,000 cache files including both databases and the media itself.

 

Whilst Premiere is creating the media cache I can work quite happily on the project but as soon as it completes my probems begin. The first sign of problems are when opening the project and watching the thumbnails appearing on the timeline, all the time the thumbnails for all clips load then I can keep working but after saving the file and re-opening it sometimes not all of the thumbnails will load for the clips on the timeline and as soon as the playhead is dragged over one of the clips which didn't load it's thumbnial the project window will freeze and that the end of my work.

 

The only way for me to continue working on the project is to force quit premieir and then manually delete all of the media cache files. When reopining the project the media cache process will start again and I can once again carry on working until the next time I have to save the project.

 

Please help Adobe!

 

Paul.

    I forgot to add my setup as I'm sure that will be questioned.

     

    Mac Pro 5,1 12 x 2.93Ghz with 48GB Ram

    Nvidia Quadro 4000 (Hardware ME enabled)

    Latest OSX, Cuda and Nvidia drivers installed

    Media Cache is stored on one internal SSD with the Media DB files stored on another internal SSD

     

    Another interesting point is that when loading the project after deleting all of the media cache eveything works much faster including the loading of clip thumbnails etc. I would prefer to be able to not have Premier create a cache at all, if it works so well without the cache files then why bog the system down with them?

    Have you updated Premiere Pro CS6 yet?

    There are some new preferences related to the media cache and XMP files under Media that might help your situation. Have a play there while I try to find out the specifics.
