Stabilize a video using only one tracking piont I have a video that I want to stabilize, tho the video itself is very stable the subject is moving. I want to keep the subject in the centre. and there is only one tracking point that is visible in every frame, Blender asks for 8 tracking points.
Use Tripod tracking instead and this will solve without 3D reconstruction. Also send the tracker to 2D Stabilization, it is located in the Movie Clip editor's Properties panel (n-key). Now you will have a motion vector based on a single tracker.
