Tracking: 3D-Markers RED <vs> Solve Error @ 0.25 ?!?

Hi,

although the average solve error in my tracked sequence is 0.25 (meaning the 3D-markers lay 0.25 pixel away of the tracked markers on average) the shown 3D-markers in the tracking display are much more far away and displayed in RED (emphasizing this shift) - see attached screenshot.

It has nothing to do with the distortion of the footage and happens to all tracking markers. The worst solve error of an individual marker is 0.43… so these topics can’t be the matter…

Any thoughts what the problem could be?

Thx,

S.
