Ok,
1. To take a different angle shot you require moving your camera to a different position.
2. If you mean to localise a portion of a video and expand away or to a different point creating an additional motion effect then that is possible.
Power Tools > Video Crop
This will give you design tools and a motion path.
3. To rotate a video where you have taken a video with the camera on its end please use the PiP designer tools and place the video in the PiP track.
I hope some of this has helped.
