A couple of videos from the announcement of Final Cut Pro X last night have leaked out online, and you can watch them on the next page for as long as they stick around, though I'm not sure who would have the claim on these. As you would expect, the announcement shows off all the new features of the software, including the spiffy Content Analysis features, the audio track analysis and just how fast and smooth this thing is. It really is very impressive.
Part one is mostly a presentation, while part two gets more into a demo of the (very iMovie-like, actually) software. If you've been intrigued by what you've heard of Final Cut Pro X so far, these two videos are definitely a must-watch.
