This is VDJ 6 Pro, using SSL timecodes, playing Mpeg 4 video.
I took the DJ FLY video from here on youtube(changed the aspect ratio) and did some simple juggles with it. This is all one shot, no edits. Maybe not the most exciting stuff you've seen. This is more of a demo of how/what you can do with VIrtual DJ 6 and video.
I can do some more complictaed stuff than this, but not with the camera right there by my arm(like when I filmed this.) Anything you can do with real/music/vinyl you can do with video with VDJ6! (less info)
