Check out the speed and velocity methods in “Property attributes and methods” and see if they do what you want.

There’s a media cache that stores some files that speed up use of some imported files.
But you say that this is when you’re rendering (I assume for final export, not for previews). Well, those output files can take up a lot of space.
from “Storage requirements for output files”
“[O]ne second of uncompressed standard-definition 8-bpc video requires approximately 40 megabytes (MB). A feature-length movie at that data rate would require more than 200 GB to store. Even with DV compression, which reduces file size to 3.6 MB per second of video, this storage requirement translates to more than 20 GB for a typical feature-length movie. It is not unusual for a feature-film project—with its higher color bit depth and greater frame size—to require terabytes of storage for footage and rendered output movies.”———————————————————————————————————

Just a shot in the dark:
Do you use a Wacom tablet with your desktop computer?
Adobe and Wacom have identified a problem with some Wacom drivers that cause performance problems in After Effects. I’ve come to realize lately that quite a few complaints about poor performance are related to this driver problem.
Here’s an After Effects Community Help search that pulls up some threads about this.

> All of that was rotoscoped? I thought it could be but the people running in front of other people are CLEAN looking that some serious roto work
I can’t be sure, but that’s my guess.

Read this page about collapsing transformations. It should help you to understand what’s going on and how to address it.

You can animate masks by animating the Mask Path property for each. If you’re animating the position of a mask, just be sure to select the entire mask path. The easiest way to move (transform) an entire mask path is to use the free-transform mode.

Here’s a basic summary of the tools and techniques used for compositing in general: “Compositing overview and resources”.
The video that you linked to shows some good planning and technique, including getting good, locked-down shots of the background without the foreground items (the actors).
Some basic rotoscoping was probably used to isolate the actors onto separate layers, and then those layers could just be stacked on top of each other.

I’m guessing that you have frame blending turned on for the layer. If so, turn it off and see if that removes the apparent “dissolve transition”.
If I’m right, then what is happening is that you’ve got a low-frame-rate footage item (your 2fps image sequence) in a composition with a higher frame rate, and the frame blending is interpolating between the frames of your footage item to serve the higher frame rate of the composition.
If you want to eliminate the guesswork, feel free to upload a project that shows this behavior, and I’ll have a look.

Your memory settings as described in section 1 of your post are problematic. You’re giving far too little RAM to both After Effects and other applications and the OS. Read this post for recommendations.
Actually, given that you only have 3GB of RAM (which is very little for software like After Effects), you should never turn on Render Multiple Frames Simultaneously multiprocessing. You have enough RAM to feed one After Effects process, not multiple.
Check out “Improve performance” for additional performance tips.
Oh, and make sure that you’ve updated to After Effects CS4 (9.0.2). That update fixed a lot of performance issues.

You’re using Key Correct (Denoiser, Deartifactor), I see. Does your mask work when you turn off or remove these effects? I don’t have Key Correct, so I can’t try this myself, but it may be that one of these effects is interfering with your mask working as you intend.
