Time lapse video

I have two 10 min. video events of a sunset that I want to speed up to about a min or so. I move to the end of the clip, hold the Ctrl key, and move the clip to make it smaller (so it is in fast motion). VF will not let me 'shrink' the clip as much as I want, and when I preview it, it looks to be normal speed.
Is this project possible, and am I doing something wrong?

640 mb ram
30 gig hd
and a newbie working on it.
Thanks, Jon

Once you change the speed, click on the properties of the click. It will list the playback speed there. You can then tell if you really sped it up. If you did speed it up, but you want it faster, render it at the max speed to anothe AVI. Open that AVI in VF and then speed it up again.

Thats it, Thanks. It looks like the max speed is 4X. So I had to render it (in MPEG) 4 times to get what I wanted, and it looks good.
Should a 10 min. avi take up 4 gigs of space on my HD?

You should be using DV AVI instead of MPEG for the intermediate renders. MPEG can add all sorts of distortion and artifacts, and these will accumulate as you go through more and more steps to speed up the movie.

DV AVI will use about 225MB per minute, so 10 minutes should be about 2.25GB.
