If you have Windows XP or Vista, you can open Microsoft Movie Maker and see what they look like. Essentially, it's the first frame of a clip. You simply line up your clips, then do your transitions.

Non-storyboarded approaches still use frames, but instead of each clip on a storyboard being one frame wide, you're looking at the composition in a timeline format. If the clip is long enough to support two or more frames, it'll throw in as many frames as will fit.

But it's a bit different. I like the storyboard approach, better.

If I set the budget, we'd have Ares and more. Unfortunately, I don't set the budget, and Ares is just too expensive and too far out for us to accomplish our goals within the budget we were given.

If we halt the ISS, all versions of Ares, and transport Orion and Altair aboard DIRECTv3's Jupiter family of Shuttle-Derived Launch Vehicles, we just might make it back to the Moon by 2020.
