RAM Preview Question
Sometimes when I do a RAM preview of my timeline it will render the entire thing and show me the preview, and other times it will only preview like 7 seconds or so… why is this???

I answered this question for you already in another thread. AE doesn’t have anywhere to put the frames when you run out of RAM. To maximize the RAM preview you can change the RAM Preview settings (look at the other thread for details) or go to Edit > Purge > All to free up RAM that was being used for the Image Cache and Previews (this will delete any RAM previews you had rendered from your RAM).

sorry, i didn’t see the other post. I’ll try what you suggested. I have 2GB RAM… i assumed that would be enough.

[zygotesoup] “I have 2GB RAM… i assumed that would be enough.”
That’s plenty, AE can’t use more than 2GB of RAM in Windows or 3GB on Mac OS X anyway.
The issue is that the frames are being rendered into AE’s Image Cache which is held in RAM (instead of onto your hard drive as a final render) and this uses up RAM quickly, especially since AE doesn’t want to use all of the RAM available to it for the Image Cache (the default is 60%, you can change this but I wouldn’t) as it needs RAM for other operations.
AE only empties this Image Cache as is necessary to maintain enough available RAM. It can end up getting big and bloated, giving you less space for RAM previews. It’s not a bad idea to Edit > Purge > Image Cache every now and then, but keep in mind that the Image Cache is also there to enable you to work faster. For example, when you move the playhead in the timeline to a new location AE renders that frame and stores it in the Image Cache. If you go back to that frame again AE doesn’t need to render it, it just grabs it from the Image Cache.

another possibly related question – when i scrub through the timeline everything turns very light colors like white yellow and pink until i release the mouse button. I installed it at home and at work and at home it doesnt happen so im assuming its just a menu setting. Know what im talking about?

That’s your OpenGL kicking in =) I recommend changing your Fast Previews preference to ‘Adaptive Resolution.’ The switch for this is under the comp window and looks like… a comp window with a lightning bolt running through it (as I recall, I don’t have a copy of AE to check right now).

brilliant!!! what is the purpose of the open GL view??? Does it use less system resources?
