    Hey Johnathan,

    The issue is not the plugin itself. It’s the behavior that I’m seeing from blender:

    1. Create a tracker object in the video clip editor

    2. Add trackers

    3. Track the footage

    4. link to empty

    After step 4, I now have a set of empties, each one has a follow track constraint pointing to the respective tracker. However, when I try to do “constraint to f-curve” to make the empties independent of the camera. That doesn’t work. No key frames are created.

    If I copy those tracks to the “Camera” tracker object, then “constraint to f-curve” works. 

    Is that expected behavior? or is there an extra step I’m missing when working with something other than the default “camera” tracker object.
