Presence technology uses a 2 camera rig and software. We have our own well proben shooting material and cameras, and a lot of experience using them.
Presence camera is not a generic, all-purpose VR Camera. It focuses on a particular use case ( camera static on a tripod, and the action happens in front ), which solves better than other generic solutions.
Presence works by making an static 360 3D picture of the scene, and seamless integrating it to the stereo video that later films the 2 cameras.
This integration is made automatically ( again, no manual stitching involved ) with a unique algorithm of Presence Camera.
The action into the video only happensin front of the 360º of the video, and the scene must be static while taking tha 360 picture ( around 1 minute ). This allows us to reach the highest 3D and pixel quality.
We also shoot in VR180 format.
