pretty dope shots. what program are you using? i just got vegas editor and still playing with it. can't figure out how to slow down a video or rewind it in the middle of it tho if that makes sense.
Split the clip into multiple segments (cannot remember what the 'pieces' are called in Vegas). In the timeline (typically, at the bottom of the screen) right-click on the respective segment and there is an option to change the play settings (playback speed, etc.).
Not sure whether Vegas has the feature to reverse playback in the middle/at some point of a segment. If not, just clip the segment up to the point where you want to reverse it, then copy it to the timeline twice, and change the playback settings in the second segment to reverse. (Editing hint: This will look a lot better if you slow down and/or stop the video at the point of reversing direction).
