Unfortunately, to the best of my knowledge, the PD Power Tools cannot be keyframed. This means that any change of video speed is a "clip wide" change and is an "on or off" change not a gradual change. Therefore slowing a video down will, of necessity, have to be done in a series of step changes applied to small clip sections. This may suit the content but may not.
A possible workaround is to apply a fade between slowed down clips on a single track or to have several "synchronised" clips at varying speeds on different tracks and manually fade from the fastest track to the slowest.
Either way its a bit of work.
