Thanks for the clarification. Since AE does not have real-time playback, does that mean that the jittery play-back shows there’s some sort of rendering problem? I can’t play back for longer than a second or two before it goes into slow motion. Likewise, rendering starts out quick, then slows down over time.

The footage I am using is lossless animation. Could it be that this is too much for my system? I understand this might be the case, I just don’t know why there would be a progressing bottleneck. At this rate, it might take forever to output the movie.

Thanks for your response.
I am rendering to a lossless file, but my hard drive has more than enough room on it. My other drives do not have that much room on them, so is it possible that something is going to them? Is there any place I should check to make sure all info is flowing to my designated drive?

I am not using any complex processing on the clip, just some basic mattes. Also, the slowing down occurs before I even get to the most intensive sections (which aren’t even that intense).

One thing I forgot to mention is that the picture does not play back in real time when working on a clip. It stutters and/or plays back in slow motion. So, there seems to be a performance issue even when not rendering. But there seems to be some sort of bottleneck occurring as rendering progresses.

Any further suggestions?
