Mapped move to the very center of the image during tracking

[Darkstar]

Hi,
I am playing around with motion tracking and see in the log-files many moves to the exact center of the image: x=320,y=240,w=640,h=480. Does it make sense to move to this coordinates, or am I getting something wrong? I thought, that the mapped_move command should move the center of the image to the given coordinates.

Are you sure you aren't seeing the return after the initial move? Generally the tracking will swivel to the centre of motion and then after a defined period return to it's home position or a preset.

As you can see, it moves first to the center (so no move at all) and then "back" to preset1. A few minutes later it really moves to a position off center.

If you have motion that spans the field of view and only have simple weighting on then the center of motion will be the centre of the frame however I would have thought this is unlikely. Do you have images captured at the time that you can look at?
