How do you do a jerking?

Answer 1

You will want to "stabilize" the footage. The way that works is by tracking the 2d X and Y axis movement of the video and then apply the movement back onto the video in inverse. This is an involved process, and the way tracking is done varies from program to program, so you will want to search for "how to stabilize footage in __________" substituting the blank space for your program's name. Or you can post the question on Answers (although you won't get any a turorial with pictures)
