I would keep it simple.
At least in film, you can be sure that the mechanics of the projector
will flicker the way you intend and expect. But in video, every
projector is different, and there so many different technologies and
formats (LCD/DLP/interlaced/progressive) and speeds (25 for PAL, 30
for NTSC) - that is a very different animal and your work may get
away from you. Especially if it is ever transfered using compression
(such as MPEG which all DVDs require) - because compression depends
on GOPs ("group of pictures") and by inserting black frames you are
creating sequences which cannot be broken up into GOPs. Every frame
is a new scene, and you may be highly disappointed by the results the
encoders, and worse the decoders, will give you. Those algorythms
were not written for us people.
It sounds like you are involved with handicraft that would work best
under mechanical reproduction. It is also important to note that by
surrounding your single frames with black, you are recreating the
shutter principle; therefore the work is inherently connected to the
film medium and should stay true to that medium. The projector
flickers by nature, you are only accentuating it. Video does not
flicker.
I would suggest you look up the "phi phenomenon" ("beta" for
sticklers) - that is the perceptual trick you are working with and
which determines the nature of the film projector. Until recently,
video was produced by a flying spot racing across the screen line by
line, odd lines first, then even lines. The spot constructed a space
over time. A film projector does the opposite: each image is
presented as a rapid flash, and the successive rapid flashes create
time out of space. All these considerations, of how your work will be
perceived by brains, are the ultimate reasons for choosing one
technology over another.
