there is nothing to motion track imho. With a 2d background the perspective wont change abit. I used the same keyframes for camera for the replays and for the background so they match up. So I dont understand what you mean. Motion tracking the toris would make it a lot less accurate. Please point out to me some second marks where something is wrong. Because atm i cant see them. It would be easier for me to fix it then

There will be slight perspective errors always if I dont use 3d backgrounds with expectcam camera data or find the absolutely perject background replay match
