How do you sync up videos of eight different flights so that the copter is in the same place at the same time in all of them? Here's the method that I've developed. I realize that this is a pretty obscure technique that most of my viewers will never use, but I'm too proud of having figured it out not to share it.
As always, if you have any tips for improving my technique, I'm glad to have them. I am a completely self-taught editor, so there are often better ways of doing things than I've invented.
