Thank you for replaying.
yes i’m trying png sequence and also mov. and i’v allocated 2gb ram for after effect and another 2gb for other applications. also i’v moved catch allocation to different drive. i’v given 7gb for catch.
after so much crashing i found one way, it’s little silly but it works.
while rendering after some frame i pauses render and after 1-2 minutes continue rendering. sounds silly but i don’t know but that thing works and my pc stopped crashing. but that trick is not helping with cs6 only works with cs5.
I will try with tiff. hope this will work well.
