Recording Equipment
Important part of 3D-video recording is camera rig which fixes both camcorders in the same position.
Stereo-base (i.e. distance between lenses) should be 6-7 cm, similarly to distance between human eyes.
This natural stereobase gives together with standard focal length (~50mm in equivalent of 35mm) of the lenses a natural stereoscopic perception.
Here are photos of a 3D-rig which I use for 3D-video recording:
