This is a Excellent Video Training Course on Learning SynthEyes.
SynthEyes is a program for 3-D camera-tracking, also known as match-moving. SynthEyes can look at the image sequence from your live-action shoot and determine how the real camera moved during the shoot, what the cameras field of view (~focal length) was, and where various locations were in 3-D, so that you can create computer-generated imagery that exactly fits into the shot. SynthEyes is widely used in film, television, commercial, and music video post-production.
