it seems that pftrack not very good at tracking mp4 footage. I of course converted them into png sequence before hand, I even tried using a proper camera to shoot, but since its mp4 again, so out of luck, barely got the track done, has to be done with auto tracking instead of user track....
Iam kinda dissapointed, coz there;s no any "advanced" stuff. Just simple box-object tracking. Its good tutorial tho. Its just when i saw title, i was hoping for some advanced stuff
