The user-generated content bandwagon rolls on. Jumpcut is a web service which enables you to edit small movies (add soundtracks, efffects, etc) in your browser. According to this New York Times report, there are lots of workalike services on the way:

Eyespot, Grouper and VideoEgg, have been introduced within the last year. This summer, they will be joined by another site, Motionbox, based in New York.

Their shared objective, the founders of the sites say, is to reduce the complexity of video editing and to reduce the cost to zero.

“We wanted to make video editing over the Internet faster than desktop editing,” said Jim Kaskade, co-founder and chief executive of Eyespot, based in San Diego. “We think it will broaden the base of people who are creative, but may not have thought they were, by creating this tool kit for them. Editing video is eventually going to be as simple as sending e-mail.”

Mr. Kaskade refers to the process as “mixing,” however, saying he believes that the term “editing” may sound labor-intensive to the amateur videographer. Previously, putting together a multishot video like Mr. Moore’s would have involved installing and learning to use a piece of software like iMovie from Apple, Adobe Premiere or Studio from Pinnacle Systems. Some of that software is packaged free with new computers or sold for about $100.

The analyst firm Parks Associates estimated last year that only about four million people regularly use such software for video editing — far fewer than the number who capture video using camcorders, Webcams, digital still cameras and cellphones.

But with more videos of soccer games, weddings and cruise vacations being posted online — and potentially being seen by people who have not been dragooned into the living room for a showing — editing gains in importance, Mr. Kaskade says, even if it involves trimming only the dizzying camera whirls at the beginning of a shot, or the inevitable question, “Are you taping right now?”

The bandwidth implications of this are interesting. All of the sites, except Grouper, require that video clips be uploaded to their servers before they can be manipulated. That can take a long time, and there are limits to the size of the files that can be sent. (For Jumpcut, the limit is 50 megabytes per clip.)

Grouper users have to download a free piece of Windows-only software that works in conjunction with the Web site. It permits users to trim and rearrange clips on their PC and upload only the finished product, in compressed form.
