Zero-cost digital video editing tools online

There's a new breed of websites that enable a user to upload his/her digital video, edit it, add effects, transitions, and titles, and share it with others. Obviously these tools will not be in league with programs like Final Cut Pro and Avid but for shoestring producers who are honing their chops, they're worth a look. The services available now are Eyespot, Grouper, Jumpcut, and Videoegg. Another highly-touted program, to be released soon,is Motionbox.
