And the winner is ... Motion JPEG!
A really useful article (many thanks to the many people named in the article for doing the hard work!), on the best codec for encoding video clips for VJing. I wish I had read this before I plumped for Photo JPEG - dagnamit!!
PS: Check out some of the neat Quartz Composer experiments that Momo the Monster is posting up on The Lava Flow. Sweeet
