The last link - Machinima for dummies, has a great clip called the The Dumb Man. Even if Machinima is not your cup of tea, this clip demonstrates a lot of imaginative ideas and good storyboarding, something that's necessary for a decent music video. There's not a lot of motion on the part of the "actors" on the screen, but there is a lot of clever camera work, so if you've got clips where people aren't doing much, you can spice it up using some of the ideas in the clip.

I will point out that this is a a spoken word video and not a music video. Music videos tend to have more shot changes - every 3 seconds or so - while in regular videos there is more time to develop mood.
