I had read your informative post at the oculus forum. Re builtin stabilization: The Sony HDR-as100v I was using features builtin stabilization, but this severley reduces fov. It was turned off for the tests.
Re rolling shutter:
This is really something I was wondering about.
1.The Sony has about 50% rolling shutter speed as measured by the method suggested on the deshaker website.
2. My own code does no rs compensation. Any attempt I made created more damage than benefit.
3. The other stabilizers of my test (After Effects, Deshaker, Youtube) all perform rs-compensation. In After Effects and Deshaker I could turn it off with little difference.
My impression after hours of tests and seeing many processed videos is that what is sometimes attributed to rs is really distortion due to wrong stabilization. The mentioned stabilizers use 2d-operations which (with the exception of roll) do not correspond to any physical movement of the camera and hence introduce distortions. You can see these breathing-type distortions in my testvideo.
