Hi! I have a very annoying problem in Blender v2.76. When I try to track I always get “At least 8 common tracks on both keyframes are needed for reconstruction” and then also “Three tracks with bundles are needed to orient the floor”. It doesn´t matter if I choose the trackpoints myself or if I do a detect features. I have not been able to track anything in the newest version. What could be the problem (because I´m screamin my lungs out and the neighbours are complaining!)
