I did these a couple of years ago just using enveloping on vegas

These days I'm using Final Cut, but the I think the basics are pretty similar for most multicam editors

oh make sure your videos are in sync all the way. one time i forgot to check and it end up one of the angles had a couple of dropped frames, making the back end out of sync.
i'm still having issues colour correcting for angles that are vastly different, but thats a whole different problem.
