Stereo 3D Test

This is just a short clip in RED/CYAN Anaglyphic format. Pull out your old paper glasses and take a look.

Stereo 3D video is becoming easier to produce.  Companies are releasing 3D camera rigs, 3D camcorders, 3D monitors and TV’s, and now Sony has stepped up and with Vegas Pro 10, releasing a fabulous suite of functions for post production.

Stereo 3D Rig Zi6's

Zi6's make a stereo rig

This clip was shot with my ghetto stereo side by side rig; two Kodak Zi6′s screwed to a piece of strap metal.

It was then combined in Vegas Pro 9.oe, and output as an AVC file.

The original is in HD and actually looks a lot better. Stereo 3D does not survive compression for the web very well.  Yuck.

Vertical alignment is the biggest pain, as well as no way to preview convergence in the field.  I was just guessing and some worked and some didn’t.

Besides vertical alignment problems, a ghetto rig like this does not have synchronized shutters.  That means the left and right eyes can be as much as 1/2 a frame out of sync.  That only becomes a problem during heavy movement.  For the cost and effort … ?

The Zi6′s are not the greatest for making a ghetto stereo rig.  The tripod mount wiggles in the camera.  The Zi8 has a firmer mount so I will probably try a build with them
