3D Image stabilization.
When using two cameras, we normally turn video image stabilization off to avoid having the individual cameras do their “own thing” with stabilization. However, I shot a test clip using “dynamic” image stabilization on both of my Canon Vixia HF M301 video cameras and the results were quite good.
Just don’t do any rapid or jerky camera movements or things really well go haywire. But for basic handheld shots or this walking shot, it works okay!
I just set up a new Youtube channel at http://youtube.com/3dStreams and am thinking about putting most of my 3D stuff there.
