Problem with rendering
Hi there,
I’m very new to AE7, and I’m having a problem with rendering. Or maybe its not rendering, just playback.I have a 17″ MacBook Pro 2.16 with 1GB of RAM, and when I import a simple 20 second DV sequence, it takes a while to “render” when I push play, as it goes over each frame and puts a green bar over that frame. Ok fine, not sure why it needs to render an un-effected clip, but that’s life.
However, after about 7 seconds, it carries on, but for each frame it “renders”, one frame from the beginning has to be re-rendered. What I mean is, as the green bar grows, once 7 seconds elapses, the head of the green bar dissapears as each frame on the tail grows.
Does that make sense?
What am I doing wrong? I know I’m not using a tricked out Quad Xeon workstation with 8GB of Ram, but… come on..
Thanks for anyone who replies.

Welcome to AE.
AE has to render EVERYTHING. You have to forget the notion that it will play back in real time, because it won’t. So just keep your fingers off that space bar.
AE is not an editing application — it’s first and foremost a compositing application. It’s meant for making changes to the footage you have and combining it with other footage. It assumes that you’ll be making fundamental changes to your video, or you wouldn’t use it; you’d use an editing application.
Depending on whatever else you have have running at the time you’re using AE, 7 seconds sounds about right for a full-resolution RAM preview on a MacBook Pro with 1GB.

Increasing the RAM will increase the # of frames that can be rendered. The green bar represents the frames that can be cached in RAM for previewing. You can set the work area to just that many frames so it will restrict the RAM preview only to the # of frames it can do.
Other choices would be to reduce the frame resolution and to change the RAM preview to render every other frame.
