Never experimented with de-interlacing 3D Video images. It sounds
like it would be difficult to achieve, unless someone can reprogram
it, to capture two consecutive fields. If not, whenever those DVD 3D
Videos come out, it should offer a better signal in pause mode to
capture two sequental fields. In the meantime, pausing the video
as you found out degrades the image. I have the first version of
the software that comes with Snappy and IF you have the second
version, it might have some more/better features that might work.

In the first version there are different capturing modes available.
Moving Video mode, grabs one field. The other modes, are for capturing
still images and sample 2 or more fields. Problem is, as you found
out, is they are at very different times and this causes a problem
in live video and pausing degrades the signal. Hopefully, you'll find
a solution and share it with us. 

In the meantime, of course the Snappy is great for other 3D projects
like grabbing 2D moving camera scenes and converting them to 3D or
taking live camera feeds and generating left/right stereo pairs.
Even converting Realist format, V-M, 3Discover, negative, etc.
into digital format works very well. Won't be as good as a dedicated
scanner but is better than nothing!

I have some examples of using a Snappy and grabbing frames from a
moving airplane, videotapped and grabbed from broadcast television
and then converting them into 3D. An example is shown at 
http://www.generation.net/~jacob/seattle.jpg 
in anaglyph form. The quality is not so great since it was converted
from video tape/pause mode/anaglyph/ and finally converted to jpg.
PHEW, nonetheless it survived its transition to cyberspace.

As mentioned it also works pretty well with converting slides in
whatever form into digital format. I have commented on this before
and I had put up some examples awhile ago. For those who want to
see an example of a Realist stereo pair, check
http://www.generation.net/~jacob/eyeball.jpg
and http://www.generation.net/~jacob/tintin.jpg for a V-M scene.

And if you want to see what a B&W Quick Cam can do, check 
http://www.generation.net/~jacob/quickcam.jpg
This is a stereo pair, also converted from a Realist slide but
the image is starting to suffer appreciably, but can be done!

P.S. Also done with a snappy and videocam. And yes the 3D animated
pumpkin from last year was also done like this. Still up at

for Halloween!
