There are many alternatives for making field-sequential 3D videos...

Firstly using real video cameras:
(1) The Grandest of all 3D video cameras is the Ikegami LK-33.  A broadcast
    quality dual camera system (i.e full resolution) which allows stereo 
    zoom while filming - normally difficult without losing alignment.
    The outputs of this camera are usually sent to two Betacam SP decks but 
    it could equally be sent via a 3D-Multiplexer (3DMux) to generate 
    field-sequential video.
    Don't expect much change from your purchase when you sell your house.
    StereoMedia productions in Burbank have 2 of these cameras.

(2) Use a 3D multiplexer with a pair of genlocked video cameras.  
    Different versions are available for composite video, SVideo and YUV 
    video.  3D multiplexers are available from several places.  
    3DTV corp:   http://www.3dmagic.com 
    QD Technology: http://www.stereoscopic.org/1996/sd96phco.html
    Curtin University:  http://info.curtin.edu.au/~iwoodsa/products 
    NB: a 3DMux which works with non-genlocked cameras is available
    from 3D Image Tek corp  http://www.imagetek.com  (price is US$2400).
(3) Find beg or borrow a Toshiba 3D camcorder.  This camera is getting
    quite old now so I'd be surprised if the resolution of the camera
    compares very well with the new 2D cameras.  The output is 
    field-sequential 3D.
(4) The NuView attachment for camcorders is a very easy and cheap way of
    generating field-sequential 3d video.  It attaches to most camcorders
    and works with the camera's zoom.  From what I've seen it generates
    good output for most situations but has a few limitations if you
    are really wanting to push the boundaries: fixed interaxial, can't
    film close objects (<1m), can't zoom out too far (i.e. wide angle).
    Available from 3D video inc.  http://www.3-dvideo.com

If you are wanting to create field-sequential 3D video animations i.e.
computer generated 3D, there are many rendering packages available but
not many (if any) provide bundled 3D support.  VREX sell a plug-in for
3D Studio Max which provides 3D support.  http://www.vrex.com
Other packages could be used to generate 3D but you will need to
manually set up the cameras yourself, and how you get the output in 
field-sequential 3D will be application specific.

Cheers,
