(Sorry for my bad english, i'm italian)
I just installed the new Kdenlive 0.9.4 and MLT 0.8.8
I'm looking for motion traking / face traking but there isn't between the effects.

I plan to make a montage like this:

What should I need to do?

Thanks a lot!

THe workflow is explained in our online doc:

Ok, but how can i move a text and not a mask? (like in the video)

It is explained on the page that j-b-m mentioned under Motion Tracking
