I'm trying to overlay 3D scene with a 360 video. The 360 camera in the video is fixed, so I don't actually need the tracker for stabilization, what I'm trying to do, is to render my objects in 3D view, then overlay the outcome on top of the 360 video in the Sequence Editor. I created the markers in Movie Clip Editor, Solved the Camera Motion, selected 3 markers and hit Floor in the Solve Panel. The problem is, I can't get the floor to be in the right position, the result change when I select different markers to define the floor. Please check the images. I thought to try to set the floor manually, add few cubes and eye ball the camera, and this might work for this example, but what if I'm working on a different scene where I actually need the 3D camera to track the movement of the 360 video? All I can think about, is that I'm missing something that I need to check in the Movie Clip Editor, to tell Blender that this is a 360 video.
