This is so cool I just don’t know what to do with myself. Let me give you some background. In the early 90’s a really cool machine came out called the Video Toaster. The Video Toaster was the first video editing setup geared to the home user, but it was so well done, it often found it’s way into professional settings (the effects for the Sci-Fi series Babylon5 were done on the VT). Interestingly enough, the Video Toaster was nothing more than a Commidor Amiga with specialized software.
So what’s my point? The VT software has been released as open source.
