How do you import character animation into Unity?

Does unity support some standard mocap or character animation format?

Not sure exactly what you mean by mocap
but you can Import FBX file format models with animation

Here’s an example of mocap (from a Vicon system, I believe) exported from Maya as an fbx file:

Thanks. Is there anywhere on the Internet to buy these mocap files? I know TurboSquid, but I don’t see what I’m looking for. I’m looking for a good set of baseball animations, preferably with a cartoony feel to them, which seems very hard to find.

The animations I have are from a collaboration with my friends at ElektraShock, http://www.elektrashock.com/

I also talked to these guys a bit at Siggraph:

but it seems to me you won’t find any animations libraries for sale in the same price range as models shown on TurboSquid and the like. I could be wrong - if so, tell me where!
