I tracked a scene and it seems absolutely perfect until you have a look at the 3d viewport.
all markers seem to have the same Y value (there's just reaaallly realllly little differences)! Now, to make the markers fit onto the original footage again the camera stretches everything along the Y axis until it fits the 2d tracked points again.
When checking the tracked properties I found out it uses an aspect ratio >15.
I tried a lot of different camera settings, tried disabling all point relations that gave info about the Y axis etc. but it doesnt seem to have any effect.
Any ideas why this is happening?
