To do video editing in the past, you often needed to rely on an application, often costly, to make any edits. Windows Movie Maker and IMovie are both excellent steps in amateur movie creation, but a new site, called Jumpcut, has recently caught my eye.
In this completely online editor, you can edit movies, add transitions, apply audio, and share your creations with others. The editor is fairly simple to grasp and within a few tries I would guess that most average computer users would be editing without a hitch.
This simple system for editing and publishing makes this tool ideal for vodcasting and video commentary. The only drawbacks are the lack of download options and the limited embed options.
The service is currently in Beta so the developers may address some of these problems once the final product is released.
