How do I make a music dance videoWatch
How would I be able to put his audio file over a dance video what software would I have to use?
Pirate FCP or Premeire cos they have the effects you want. There's a lot of neat features that allow you to do quick cuts and glitch effects. Search up rap video tutorial on youtube and you'll find plenty of videos on them, they're fairly easy to do. As for a camera, you don't really need anything better than a cameraphone, just have an interesting premise.
