Actually, I think Migel may be right - I've tried a few quick movie clip animations, and Blender is slow in rendering them, frame by frame. To answer your question Migel, no, I'm actually new at this animation stuff.
I've given it some thought - what might be easier would be to simply import the models into a quick app with some graphic engine, Ogre, Irrlicht, or something else, and record it. Doing so would sure take a heck of a lot less time to create a video clip, and I do know how to code such simple things, I've done it before with my own sample projects. I think it would also take advantage of the new PCI Express graphics card I have now, instead of slowly using Blender's internal render engine.
Blender makes nice pictures, its just really friggin' slow...
