Could be that the GPU is overheating during the process and thermal protection kicks in. Or your drivers are out of date.
>Nvidia GeForce GTS 240
I don't know about that specific card, but I have read that many/most PPro users have had to update their nVidia drivers when using CS6
What is your driver version, and have you gone to the nVidia site to check for an update?
I checked and I already have the latest nvidia drivers. My GPU usually
never runs over 56 degrees centigrade even while rendering video. What I
don't understand is that it plays the videos fine, but when I try to render
the timeline or export it, it will render to a certain point and crash. At
first It would crash at the point when it began to render an gaussian blur
on a video. So I got rid of the gaussian blur and tried to render it again.
It rendered further this time and I thought I solved the problem until it
was almost finished rendering and it crashed at ANOTHER point on the
timeline!!! This time, it crashed when it reached a clip that had a SIMPLE
Film dissolve on it!! The timeline also included clips with warp stabilizer
and a dynamic linked after effects comp. It can render Dynamic link comps
with 3d camera tracker applied and warp stabilizer but it crashes when it
reaches the point of a gaussian blur and a film dissolve???? That makes no
sense!! Anyway I ended up just exporting it with the RAM. Sure it took
longer but it didn't crash. Maybe it has something to do with certain GPU
accelerated effects. I just hope it doesn't crash while rendering ultra key
clips because I rely on that effect for so many projects!
Anyway, Sorry for the long-winded message and I appreciate your suggestions!
>have the latest nvidia drivers
Well... that actually MAY be the problem, according to http://forums.adobe.com/thread/1084197
Your is not a model 285, but is IS an older model that may not work properly with the latest driver
Try version 296.10
Thank you for the suggestion. I will try this and see if it works!
