I have an AMD Athlon 4600+X2 w/4GB RAM on an Asustek M2N4SLI MB.
I don't know if I'm pushing the envelope, but sometimes Cinelerra has a
little trouble with "heavy lifting" when I keep adding effects on top of
videos on top of more effects. Here's the latest one I did:

As you can tell, I used lots of chroma key between 3 layers of video.
Cinelerra kept dragging more and more as threw more "rocks" on its
back. The timing was getting thrown off, so I had to keep stopping and
starting the composite playback to find my insertion points. It was
reaching a point where it seemed to be saying "no mas, no mas" because
it didn't even want to play videos in the preview window properly.
I figure that I need more processor power, so I thought I would do it a
favor by rendering a .mov, then use that as a separate layer for further
editing. Cinelerra couldn't play it's own rendered .mov. I know that
it was 65 MB unoptimized .mov, but that was strange to me.
I had to satisfy myself with only 3 layers of video.
(Unfortunately, my brainwave entrainment video doesn't flash properly on
any video server, so it's choppy rather than flashy.) The web cut the
power of that video in half, but I'm pretty satisfied with the final
product. If I put it on a DVD, I'm pretty sure it could rip a few heads
off.
