Field-sequential video tapes can be duplicated the same way as any 
regular video is duplicated - VCR to VCR.
Converting a field-sequential 3D video tape to 2D is a relatively simple
process of doubling the fields you want and dropping the fields you don't
want.  e.g.  left image fields are copied over the top of right image
fields in the output signal.  
We have a box which does this (but its primary purpose is to convert 
field-sequential 3D video between the NTSC, PAL and SECAM video standards)
and it works wonderfully.  
Some people may wonder why you'd want to take the D out of 3D but you
may may wish to show a particular video to a large audience and you don't
have enough glasses or the right 3D projection equipment, or you may wish
to include some video shot in 3D into a regular boring flat 2D video 
sequence/compilation. ;-) 

Another box which will do the 3D to 2D conversion job is a "3D Demultiplexer".
Such a device is normally used to drive a pair of video projectors for
large screen 3D video projection.  One projector projects the left eye image
and the other projector projects the right eye image.  The demux
separates the field-sequential 3D video input signal into two separate
video outputs, one left images video signal and one right images video
signal.

We have both boxes for sale and also offer video conversion services.
