Here’s some really clear images and videos that illustrate a VR Video assembly process using a 6 camera go-pro rig. This isn’t meant as a comprehensive how-to, rather, just a visual only guide that I will be using in presentations to walk folks through the process.
Step 1: The Rig (6 gopro cameras)

Step 2 – Shoot

Step 3 – Raw Footage
Step 4 – Exploded View
Step 5 – Equarectangular Stich (rough)
Step 6 – Spherical Playback
