YouTube adds Magisto automatic video editing tool | Digital Media - CNET News: Now any video being uploaded to YouTube can be edited automatically. No manual intervention is needed whatsoever--just one click of a button--and Magisto's tool instantly "finds" the best scenes in your video and cuts out the blurry, bad and boring bits. Music and effects (wipes, transitions, titles, and fades) can also be added with two button clicks. The tool is dead simple to use as it literally walks you through the editing "process" in seconds.
