Tracking ball shape in Hitfilm Pro
I've got a pretty basic understanding of vfx terms and stuff (been using other software on and off for a while) but still open to cave-man speak lol.
I've got a ball in my clip that i would like to track through the air. The specific clip in question is a recording of a match in a game called Rocket League. i thought this would be a nice challenge to learn some new skills as a hobbyist, however i have run into this issue.
Using mocha, it tracks only to one point on the geometry of the ball, and as the ball rotates, the shape of my mask//outline moves with the rotation rather than simply the movement of the circle across the 2d plane (meaning the outline will like, "pinch" itself as the part of the ball that was facing the camera in the beginning rolls away.) (happens even if i only have it set to track translation, which tells me i don't understand how mocha actually tracks things.)
Using the "add tracker" button in the composite editor has the same effect, it tracks to a point on the ball instead of just the circle shape, rotating the outline with it.
My question: is there a way to track to the circle shape in an automated way, or am i stuck masking by hand?
