‌Setting Up a Coordinate System ‌

You should tell SynthEyes how to orient, position, and size the trackers and camera path in 3-D. Historically, people learning tracking have had a hard time with this because they do not understand what the problem is, or even that there is a problem at all. If you do not understand what the problem is, what you are trying to do, it is pretty unlikely you will understand the tools that let you solve it. The next section is an attempt to give you a tangible explanation. It’s silly, but please read carefully! Please also be sure to check out the tutorials on the web site about coordinate systems.

Observation : many new users who say they are having trouble setting up a coordinate system instead do not have a correct solve for the following reason. Frequently, first "test shots" are handheld, with the camera pointing in different directions but no real camera translation. They are nodal tripod shots, with no 3D information present, so any attempted 3D solve will be incorrect and impossible to set up a coordinate system on (use Tripod Mode to address them). Other frequent new-user issues include severe lens distortion, and trackers on moving objects such as actors or cars. Be sure to look at the 3D views to establish that the solve is qualitatively correct before attempting to set up a coordinate system!
