How much RAM do you have installed and what is your processor?
I ask this, as I have found that if you have 8 threads running (i7) and only 4 Gigs of ram, the importerREDserver process can consume as much as 2.5Gigs of ram for EACH CPU thread. I have found that when the timeline requires multiple R3D files to be threaded simultaneously, this can cause the system to lock up as adobe will be requesting 16+ Gigs of RAM.
Are you using Windows or OSX?
If Windows, open your Resource Monitor and watch your Memory usage and see if the importerREDserver is eating up your memory.
Unfortunately, I don't know what the fix is for this other than more RAM.
I'm using Windows 7, 4Gb RAM, AMD phenom II x4 940 3.00Ghz and I have a Nvidia Geforce GTX 285.
I'll check now the RAM usage. The Thing is that the computer doesn't lock up or anything. Everything runs smooth. but the render percentage doesn't increase, the status bar doesn't move at all but premiere, AME or the rest of the system still works and you can interact with it.
I know im tight on RAM. my near future plans is getting as much as my mother board can handle. Actually I was surprised I was able to edit with no too much problems just by lowering the quality of the preview. I even tried the performance from an external hard drive and was fair enough. just having problems with the audio as it was going off after a few seconds cause it was too much for the USB 2.0. I think adobe did an AWESOME job with cs5 (unlike cs4 that was a mess and I started using Final Cut again)
I just installed the latest update, gonna try now.
Didn't work. Same thing Happening. I'm going to try in a different computer in my school.
Ok, Exported successfully in prores 422 HQ in a mac with just 4gb of RAM and working totally from the USB Hard Drive.
Now I guess it's time to guess what's wrong with my PC...
