Vegas method of velocity changes is best in class. But getting speed above 300% by using nesting is WORST in class. Why can't we punch in 3000% if we want to like all the others? I am nesting one 4 sec clip by ctrl drag in - velocity env max - save project open new proj - nest previous - ctrl drag in - vel env max so i would guess a 600% increase and of course as with all nested effects it is unviewable so to render it out to HDV for 4 seconds and only the velocity change it is a 40min render on a Q6600 quad....
