Brushless gimbal stabilization for stereo Rift videos

On the Oculus subreddit I have a new post about a brushless gimbal stabilizer rig I have built for my Gopro/Sunex stereo 180 video camera

-- and links to a recent equirectangular video software stabilization method

    Here is another short movie shot with the stabilizer -- with my rig held over my head. It works great for stabilizing pitch but it needs a little more torque to be rock steady with roll so I will get another, stronger, motor for the roll axis.

    In VR Player you need to set:

    Media/Format/Side by Side
    Media/Projection/Dome
    Tools/Settings/Display/Horizontal offset to 60 (or to suit)
    Tools/Settings/Display/Camera/Fov to 95

    I installed a stronger (heavier) motor for the roll axis and now it works with stronger action. Here is fast walking (one camera, unprocessed, unsharpened Raw) -- it shows the cameras stay level, even if it is not affecting yaw or up and down walking motions. But levelness is an important thing for comfortable Rift viewing.

    Here is WarpStabilizer (After Effects) applied to (level) two axis gimbal stabilized equirectangular 170 degree frames ..

    and without WarpStabilizer

    WarpStabilizer is so effective here because it only has yaw to stabilize and with level equirectangular (or cylindrical) frames yaw stabilization can be obtained with simple lateral image shifts.
