Launch: Edit your videos with the YouTube remixer
YouTube releases a video editing tool which remixes your 'tube clips using a Flash-based in-browser application.
Drag and drop your clips to a timeline (much like iMovie) and add music, effects, graphics, captions and borders. The remixer is throwing a couple of "still working out the kinks" hiccups here and there this morning, but it's still a fun and easy way to splice, slice and dice your clips together.
