Camera Tracking "Crane shot" with subtle Parallax?

Question

Hi everyone,

I've learned how to camera track in various situations but this is one that I have never delt with. I basically want to add a bunker entrance in the mountain but I can't seem to establish a good ground plane. I'm using Element 3D to view .obj files in Ae but I'm also open to Blender if easier. How would you approach this "set extension"?

I uploaded the clip I sent to Ae from Premiere Pro. The uncut clip is longer. (I added Lumetri Color to help tracking since the original is Raw)

I tried Camera Tracking with Advanced analysis on your shot and got this in about 4 minutes. If you must add a 3D object to the scene then make sure you set an origin and ground plane first that sticks (the pale blue layer in the center) and then several other solids to the scene and rotate them so they conform to the geometry as well as you can. The back center worked well. This is a shot that needs advanced analysis and a bit of work to lock one of the surfaces to the scene, but it is doable.

If you can approximate the position of the bunker and render a still image of it Mocha AE Corner Pin or Stabilized Power pin as shown in this tutorial will work. I don't see any reason that this shot can't be tracked successfully in After Effects.
