As I'm moving and key-framing everything, it runs pretty smoothly. But when I try to render, it sometime stutters and freezes.
I don't understand what you mean. Are you saying after you render it and then try to play back your render the playback isn't smooth? If that's what you mean, read this: FAQ: Why is my output file huge, and why doesn't it play back smoothly?
Hey Szalam, yes, play back is slow, but also while I am working it freezes and stutters occasionally. But thank you, I will check out the article.
Your system is certainly on the low end. 8 GB is the minimum to really run AE. Adding more would likely improve things.
Alright. I think overall RAM should help everything. Thanks for you help! RAM is pretty cheap too haha
