Anton over at the 3D Vision Blog takes two Sony HDR-SR11E high definition camcorders and builds himself an inexpensive 3-D camera rig. It is a nice setup. Head on over there to learn more about how to do it yourself, and to learn some of the shortcomings of it.
If you are making a custom dual camera rig for shooting video in stereoscopic 3D format, then you’ve probably ran yourself with some issues in actually getting a live 3D preview in order to setup the cameras correctly for the subject you are going to shoot and even if you just want to properly align the two cameras. Of course the two cameras/camcorders must be the same make and model, but even that does not guarantee you that they will be perfectly aligned with each other, so you might have to do a little bit of additional tweaking in order to get the proper vertical alignment of the two lenses. Here I’m using two Sony HDR-SR11E HD camcorders (on the photo above) and as you can see I’ve connected the video out cable to each other, something that is not so convenient on this model. The closest interocular distance I could get with the SR11Es was about 8 centimeters in a parallel configuration, but with the video out cables connected the minimum distance goes to about 10-11 centimeters which is not very useful for filming close objects in 3D. However it has worked very nicely helping me properly align vertically the two cameras, because they’ve had a bit of an offset as you’ll see on the photos below…
