Hi

I'm sure there must be a simple way to achieve this, but I just can't find it.

What I'm wanting to do is take the tracking data from the motion track, and apply it to the x axis only. With every option I look at, it seems the x and y data are locked together both in the tracker and when apply tracking data to other nodes.

It's such a fundamental thing to be able to do that there must be a simple way.

Any help would be greatly appreciated.

Hi,

Simple indeed!

Go to prefs-Splines, set tracker path to xy

Do your tracking, go into spline editor and delete the y track

Good luck!

If you don't want to retrack you can also do this: connect the path to your center then insert an expression modifier on that center. For the position output enter "p1x" in the x field and 0.5 in the y field.

It can also be done by selecting all points of the path in the view and either shape-box'em and squash the path along the X axis till the path become a straight line with Y displacement of zero or hit ctrl-E and group edit the Y values to .5 or whatever.
