Ever wanted to download a YouTube video to use in a class, only to descend into a hell of incompatible video codecs and obscure media players? That’s because YouTube usually displays in FLV video, a weird flash-based video format that doesn’t play well with others.
Just add the bookmarklet on the following page to your browser bookmark toolbar, and click it when you’re watching your favorite vids to show a “Download as MP4″ button. The MP4 you download will be higher quality than the .FLV video YouTube normally displays, and it’s more likely to work with your video editing and playing software. AWESOME!
