Nuke Camera Tracking

The footage which i'm going to use for the project. Captured by Ipad Air 2.

Before bringing into Nuke, I converted the .mov file into 250 tiff frames using after effects. The scene is set to be tracked and exported as FBX. 

The tracking seem to be good due to the depth of field. The focal length is set according to the Ipad lens between 3.3 mm to 4.0 mm. 

Here is the 3D view in Nuke. The tracks are ready to be exported.

The FBX are imported into Maya as locaters and track camera. I placed the camera position and scaled the locaters down to fit within the space and in line with the sculpture model.

In the camera viewport, i continued to adjust the perspective till it matched closely to the frame angle. Unfortunately, the first half seems to be not in line with the footage but the second half is fine. 

Due to that, i decided to start the crackup at 120 frame. I will export the sculpture together with the tentacle as FBX into Houdini to create the crackup effects.
