    the giant walked on green screen with tracking marks

    and, in the snow scene footage, there is a pole walking instead while the camera is following to that pole(the camera is moving)

    so, how they match or track these 2 footages?

    I dont think so

    In that tutorial, just used a background picture and make it look 3d

    but in my video, it’s a footage which has camera movements

    Hey Tom,

    In the snow shot, it looks like the pole isnt really being used for motion tracking, as much as its being used for timing to know when to pan the camera of the green screen shot.

    Does that kind of help? Or are you wondering the specific kind of tracking like Match Moving or 3d camera tracking (syntheyes, boujou, etc?)

    I don’t see any other way to do that shot properly than with a motion control rig. And then at that point, it’s not really a tracking job anymore, just matching the motion control so that both shots are in sync (and then after that move on to the rest of the compositing of course).
