Okay, this is not amazing mograph or genlocked hi-def, actually maybe the most interesting thing about this longish video is that it has been shot on a single 1CCD (canon MV300) camcorder, with an old 90' style adapter on it
That's actually a youtube link but the embedded player doesn't support stereoscopy.

Hi Filip,
The URL in your post above didn't work - YouTube described it as a "malformed video ID" so can you try again?
Also, your post was flagged because it contained a TinyURL. We don't allow them because so many spammers use them to hide naughty bits. Instead, please use the "L" button above the post composition box. Select the text you'd like to embed the link in, press the button, and paste your URL in the href section.

I see some glare flashing in and out of one eye or the other. I think you've got some light hitting a mirror on your rig? Or hitting one of your lenses not the other, you might want to rig up some more light shielding. Really clear and clean otherwise though.
I get into arguments with my associate about 3D handheld. I think it works fine, if it's done as smoothly as possible, in the classic style. He insists it doesn't work, has to be on Steadicam, that any yaw is disastrous. I'm not sure, I like the handheld shots in the space shuttle video I shot, but I did try to keep it very level. Maybe my eyes just accept if more than others do.

Thanks for your reply Steven.
Yes I might have to invest in a sunshield, now that I found that I had a ring to fix the adapter to the camera.
I wish it was all steadicam, but I just wanted to see how much I could get out of it. One of the things you notice straight away is that objects that are clearly separated in depth from their surroundings work much better than all the angled lines going into infinity (that was surprising, I always thought a tunnel is the best case scenario.
I tried to move the camera horizontally as I learned before that horizontal tracking sends much more information to the brain about the space, but of course it's a weak excuse for all that wobbliness.
Another thing that was a bit surprising is that even though L and R images are delayed by 20ms between themselves, it doesn't seem to matter that much. Static, or slow movement shots still seem to work better, I wonder to what extent that's because of the delay.
And one last detail I noticed today. In 5:01-5:12 look at the floor. Its completly burned-out in just one of the 'eyes'. I believe it has to be due to the light being polarized while reflecting off ground, but I'm not sure why that is being recorded, unless it also has 90" LCD shutters polarizing light, but why would one do that, that kind of design within the adapter seems strange. Unless that's just a behaviour of the mirrors. Just some strange angle. The effect is not apparent of the water, but maybe I just never filmed straight reflections.

Yes, Glare off surfaces is often a problem, whether you're using polarizers are not. A surface can glare from one angle, and not from 65mm away.

Ok, back from IBC, I've managed to play my stuff on Hyundai screen at digital signage stand, and an experiment with using DVD with 3d sort of failed - the resolution was really low.
Also, my general impression is that although all the camera rigs are ready to go, and some people are getting pretty impressive results with them, we still have to wait until display technologies get cheaper and more people will have screens like JVC's one at home. (I don't know what made me think panasonic and sony have released their screens already).
Thanks to everyone who watched my non-pro tests, and have a great stereoscopic week !
