jbm's blog on ver 0.9.3 mentions "Improved motion tracking: Kdenlive can also now analyse an object's motion, and the result of this can be used as keyframes for a transition or an effect. For example, you can now have a title clip that follows an object"

Hey, How do you use this feature?

I am asking myself the same thing, and still cant find it....

So... if you right click on the clip on your proyect tree and find scene cut, you will generate metadata which probably contains the info of the movement... now, how to use the data seems to be the next step...
