I want to slow down a portion of a video clip to a steady stop. I am using 4800 frame stills sequence. I want to gradually slow and stop on 9 occations. Any advice on how to do this in (trimmer) vegas? I know you can grab end of video and press control (or alt) to extend an entire clip by draging it down the time line. Does this work with a selection and if so, how can I make it taper.

Hope i explained this completely. Screen shots would help if you have any.
