Just got a 2011 brand new 27 incgh imac with full ram/ full processing speed. I am using after effects and premiere to edit a project. I am currently experiencing over the top crash issues/ slow rendering/ general reas issues when I attempt to scrub unrendered footage (it will stick on one frame for quite awhile). I am wondering if the issues can be resolved through changing the location of the files the physical files. Currently, they are being read off an external device, through firewire 800. I do have the option for thunderbolt. would it make more sense to have them on the computers HD/ would thunderbolt make a difference in the crashing/ slow reading of the files?
Also, I am plumb lose as to the best settings for the scratch disks etc. I seem to get varied opinions on this.

We need to know a lot more if we're going to help you. Please provide answers to the questions listed here: "FAQ: What information should I provide when asking a question on this forum?"
Check your system log viewer for the actual cause of the crashes. Must not at all be related to AE, could simply be the graphics card getting to hot from all this hard work. Some iMac models have been known for that. And of course Kopriva-Man™ has a point - we'd need much more info on what's involved in the project. If it's graphics related, it could just as well be some greedy OpenGL plug-in keeping your graphics card at full throttle all the time, if it's disk related, it might be a combination of external footage storage vs. media cache vs. the kitchen sink or whatever...
Thanks guys, yeah, more info would make sense.
here are the specs:
After effects CS5.5
Mac OS 10.7.3
the problem occurs when I attempt to scrub the timeline while AE and premiere are open at the same time. I am using the "raplace with after effects comp" option so that I can go back and forth between the two. The layers have had color correction, motion tracking (through mocha) and masked out layers applied to them.
I have a 27 inch imac with 3.4 Ghz of processing speed and 16 GB of RAM, AMD Radeon HD 6970M 2048 MB
my external disk is a 3 TB goFlex, firewire 800, 7200 RPM
I am using OpenGL
I am rendering multiple frames simultaneously

Have you tried with MP rendering and OpenGL off? This sounds like you are putting too much strain on your system. Also does the issue still occur if you use other footage formats? rather than a specific single cause, i think it's realyl the combination of things - H.264 decoding being heavy on hardware acceleration, Dynamic Link using lots of RAM and resources already and then on top of it trying to MP render based on a clip format, where the footage I/O for each separate instance and the memory consumptin might put the final nail in the coffin in a manner of speaking. Try to lighten this pipeline a bit and see if it helps.
Hey there! I think you indirectly answered my problem by mentioning the heat issue. I found an app that increases my fan speed and problem solved! Is this coincidence? are the default fan settings not cut out to handle the the kind of work I am doing?
I can't give you any specific info on that. Adobe forgot to send me that million dollar cheque and to date I have no iPhone, no iPad, no iMac, no Ferrari... From my fading memories from my old MacBook Pro I tend to think that it's simply a configuration issue. I'm sure there is some simple switch in the energy management settings that could fix this in teh context of the launched app or a custom desktop environment with Spaces or something like that. also you might simply lower the temperature threshold for the fan speed, so it revs up earlier. I believe these days Apple allows direct access to graphics settings and there may be some ATI/ NVidia system panel or control app floating somewhere that would allow this...
I read up on it; to preserve "energy efficient" status apple does not put the propper fan output settings in there out of the box machines. This app works pretty well though. I was also hiding a few of my diamonds in the imac air vent and I think they got stuck...no worries, I'll just toss it into the back of my land rover and get on over the apple store. Who am I kidding, why dont I just throw this one out and buy a new one....
