Tweaking the Point of Interest
This is different than moving it!
When the selected trackers are combined to form the single overall stabilization track, SynthEyes examines the weight of each tracker, as controlled from the main Tracker panel.
This allows you to shift the position of the point-of-interest (POI) within a group of trackers, which can be handy.
Suppose you want to stabilize at the location of a single tracker, but you want to stabilize the rotation as well. With a single tracker, rotation can not be stabilized. If you select two trackers, you can stabilize the rotation, but without further action, the point of interest will be sitting between the two trackers, not at the location of the one you care about.
To fix this, select the desired POI tracker in the main viewport, and increase its weight value to the maximum (currently 10). Then, select the other tracker(s), and reduce the weight to the minimum (0.050). This will put the POI very close to your main tracker.
If you play with the weights a bit, you can make the POI go anywhere within a polygon formed by the trackers. But do not be surprised if the resulting POI seems to be sliding on the image: the POI is really a 3-D location, and usually the combination of the trackers will not be on the surface (unless they are all in the same plane). If this is a problem for what you want to do, you should create a supervised tracker at the desired POI location and use that instead.
If you have adjusted the weights, and later want to re-solve the scene, you should set the weights back to 1.0 before solving. (Select them all then set the weight to 1).
