Re: Distor tool question

Put a second copy of your clip on video layer 2. Turn off video layer 1 (green button on the far left of the timeline) so you can see what you're doing.

Double-click the clip on V2 to load it into the viewer. Go to the Motion tab and use the Crop controls to remove the bottom of the video. Now you can turn V1 back on add filters as needed to the top to create the desired effect. I'm not sure what the "distort" effect you're looking for looks like, otherwise I would offer a few suggestions.

If you want more control than the crop tool offers you can use the four or eight point garbage matte filters, which are controlled from the filters tab.
