The BB360cc

The Baahubali VR experience, the first of its kind in the world, has left people reeling in awe and amazement. So. How was it done?

A custom made camera by AMD Radeon Technologies Group, the BB360cc was crafted to capture what would become the VR experience of Baahubali. The most advanced and high end VR camera built to date, here are the details of the rig.

The BB360 rig constitutes 28 Black Magic Micro Cinema cameras and was built in modules. This modular feature facilitates changing of the lens and also enables the reconfiguration of the rig to meet specific requirements.

The rig has a capacity of a 100 degree vertical field of view with triple camera overlaps on the horizon. Additionally it can accommodate 2 extra rings for capturing the top and bottom views, along with 2 optional, intermediate, rings for capturing detailed or trickily aligned shots.

With images being written at 50MB/s to a camera shooting at 1080p60 in ProRes 422 HQ, the Black Magic Micro Cinema has up to 13 stops dynamic range.

Running alongside this rig are 16 cameras, stitched in real-time with Radeon Loom technology, using AMD Radeon’s Pro GPU for real-time previews of the visuals being recorded.

With the intention of making the VR experience unique and miles ahead of the existing content on all fronts, the VR experience was edited in stereo sound rather than mono. Though most of the tools failed during the stereo stitching process, the combination of the BB360 rig and the Cara VR’s Ocula helped create beautiful stereo images, with a lot of the overlapping information between cameras still intact.
