You can post your video on either youtube or on photobucket. Most of us here already have a photobucket account, so I'd go with that. The only catch is that there is a limit on the size (300MB) and duration (10 min) of the video that you can post. Also, you have to make sure that your video is of one of the following file types: 3g2, 3gp, 3gp2, 3gpp, 3p, asf, avi, divx, dv, dvx, flv, gif, moov, mov, mp4, mpeg4, mpg4, mpe, mpeg, mpg, qt, wmv, xvid, rm
Different cameras will record using different file types, but it should be good.
Try it... just upload and link it just like you do pictures! =)
This site doesn't appear to support having the actual video play, but you can link it like so... The following is a test of a photobucket vid (sorry that it's not a fig vid...):
