i have a mac pro 8gigs ram, 3.0ghz quad core and ive been using it to edit my videos never had any issues,But lately i cant render anything over 6mins long its quitting when its almost complete saying its out of memory i have 8gigs of rum and i have rendered movies longer than what im trying to render now, Im running mac osx 10.6 I tried to install Lion but when i run the installer it says i cant upgrade to this os :-( im not trying to upgrade i want a clean install but cant do that either please someone help me with one or both issues PLEASE!!!!
Thank u very much u maybe right because this particular project im trying to render has more than 10 stills and i didnt pay attention to the resolution i will look into that and i will let you know if reducing the resolution of the still images solves the problem . About the OS installation im trying to install it from a flash drive the I restarted the computer, presed the C key and the installers launches fine but when i choose a clean install it tells me that i can upgrade to this os :-( maybe that helps! again thanks
