YouTube Remixer: Edit Videos Online At YouTube.
YouTube has officially launched YouTube Remixer, a new service that allows users to edit their videos from within YouTube itself. The new feature is powered by Adobe Premiere Express and supports insertion of graphics, text and audio as well as overlays and in-video transitions. YouTube Remixer is nearly identical to Photobucket’s Remix tool; both are powered by Adobe.

If you’ve ever uploaded from your cell phone, wished for an easy way to add titles and transitions, or just wanted to remix your own videos, Remixer is a great place to play. It lets you assemble your new video with text, audio, graphics, overlays, effects, and transitions right here on YouTube (no fancy equipment required), in an easy drag-and-drop timeline, and then publish it right back to YouTube. Your original videos will stay exactly the same.

Check out the new YouTube Remixer, available on TestTube, and you’ll be an expert in no time.
