I have some experience editing video and stuff. I am currently using FCE, but I am looking for software for live mixing. The goal is to do a short "show" of some sorts for a (small) live audience, mixing prerecorded videos, live video, images and audio. It's amateuristic and low-budget, but it would be nice to have it all go smooth. The alternative would be manually changing the input of a projector, but that's not really elegant. Any ideas?
