I have about 15 video seconds of a walking man.

I want to compress that 15 seconds to about 5 seconds. I tried holding the Ctrl key while I slid the right edge of the clip to the left.

Got a nice effect (man disppears and reappears further down the road) but its not the effect I want - I'd rather have the 'jerky' effect of walking fast with all frames instead of missing frames.

Any ideas how I can accomplish this?
