    @marcocarlucci  I think, from a strictly amateur pint of view, that one could create a tracking point or even a double tracking point and link that track data to a point layer.  Then position it where you want to the head replacement to be and import a PNG of the head you want to show and link it to the point layer.  Of course, if the time is something short like your clip 39 sec to 44 secs, you could always go at it out school by export each individual frame (but it adds up quick; 24 for each sec) and use a photo program like GIMP to layer the head over on each frame and re import the sequence.  But one of the adepts here probably has a better way, so that's just my 2 cents worth.

    marcocarlucci : @tddavis3 is exaclty right! Here is my tutorial on how to track someone's face to add the "Witness Protection" effect. What you want to do would be the same idea except you would simply add a picture over the guy's face instead of the Witness Protection effect.

    If you were trying to track in VIDEO of a face over another face, the steps are the same as what tddavis and HitfilmSensi have already written, except you would put the overlay video in its own Composite Shot first, then stabilize (and mask), bringing the overlay into your main comp as an embedded composite shot, then parenting to the main track.

    @Triem23 That's a really good idea. I never thought about bringing a video in to overlay. I am not sure I have ever seen that done before, but then again, I haven't been looking for it either.

    Hollywood movies do it all the time. It's a lot harder to do video. To make it look right, you actually have to stablize the BG plate around the head you relpace, then have that available on set for reference when shooting the overlay, so you can track it back on.
