Motion Tracking not working for Eyeball I'm experimenting with motion tracking an I'm a little stuck.
My plan is to track the motion of an eyeball from a video an let an animated eyeball repeat the same motion.

And in principle it works. If the attached image was a video you could see that the eyeball in fact moves according to the track. However only very little (track is highlighted in red).
I even get why: The path of the track is (since it is eye movement) very little. I want this little motion to rotate the eyeball by something like 45° which of course it does not.

Is there a way to sort of amplify the movement from the track?
The Follow Track constraint includes a 'Constraint to F-Curve' button - click that and Blender will convert your track into a series of keyframes. You can then use the Graph Editor to edit the resultant F-Curves for the object.

To edit a curve, right-click on one of its points and press L to select 'Linked' (ie, select the whole curve). Then use S to scale it (you can type a number to scale by a fixed amount if desired - eg, S10Enter) to scale up by a factor of 10. Repeat for each of the X, Y, Z channels.

Once you've scaled up your F-Curve you'll find that the motion of the empty used for the track is similarly affected, resulting in more motion for the eye.
