Can motion tracking and Video Stabilization constrain to y axis only? Is there a way to remove or ignore the tracking data of x or y axis? I just want to stabilize the up/down motion in a video because I'm doing a panning shot (rolling on wheels). As you can see, the red track seems to move the film to the left (outside) which is unwanted. Thanks.
In the compositor the Movie Input nodes has x and y offset values, once you add a tracker to the 2D stabiliser these become active. Just use the correction you need and plug it into the node distort>transform.
In your case just use the y value.
