Look at some comparable instructional videos for similar
(exercise, etc.) products. Even late-nite infomercials, etc. if you
don't have access to any examples of comparable instructional
videos. I am quite confident in saying that NONE of them
were produced with "webcam" type cameras. Have you ever
used a conventional camcorder? Do you appreate the very
substantial difference between a "real" camera and a "webcam"?

Perhaps off-topic for this newsgroup but if it is hand-machined
in your basement, is it commercially viable as a mass-market
product? I love hand-machining things in my garage, but have
no delusion that they could be commercially marketed with
that much hand-work. If this is intended for actual rehab
with the intent of remedying a medical condition, doesn't that
make it a "medical device" and subject to strict FDA rules?
Perhaps not something you need to answer here, but likely
something you will have to deal with somewhre along the line.

I don't understand either of your assumed predelictions:
1) Why "permanent" how many of these videos do you think
you will be making? Are you going into the video making
business in addition to making your exercise/rehab device?
2) How did you arrive at multiple cameras and post-production
editing? I am also quite confident in saying that NO comparable
videos were produced this way. And for very good reason. They
were virtually all done in a conventional "film-production style"
where a single camera was used, optimally placed, lighted, etc,
and then several takes, perhaps at different zooms, etc. were
put onto tape before moving to the next (scripted) camera
position.

I gather you have not seen very many surveillence videos?
Even full-screen ones are often too fuzzy to even get a good
identification of the suspects. Despite the fiction you see
every week on CSI.

From this, I gather that you have no video production experience.
Nothing wrong with this, nobody started out with such knowledge.
If you insist on your multiple webcam/surveillence camera scheme,
I predict that you will end up spending hundreds (thousands?) of
$$$ and end up with nothing usable to show for it.

Not in my opinion.

Do you not have any friends with camcorders? Borrow one and
compare it to any "webcam" or surveillence camera you wish. After
doing a side-by-side comparison, I think you will quickly recant of
your fascination with multiple webcams.

Buy a $500 mini-DV camcorder. Be sure to get one with a
microphone input jack and a headphone jack. I most strongly
recommend against your multiple-webcam scheme.

With a reasonable camcorder, sufficient lighting and TIME, you
could shoot enough video to edit together an acceptable video.
Have you written a script for this project? Do you have any kind
of urgent deadline for this video? It may take several months to
get things set up to produce halfway-decent video. Your 8-foot
ceilings may pose a problem trying to light things properly.

All the more reason to forget your "fixed installation" scheme
as inflexible and unworkable in the long-term.

Everything you tell us lobbies AGAINST your multiple fixed-

Theoretically, this newsgroup (r.v.p) is targetted at "production"
or the process of shooting, and the r.v.d is targetted at post-
production (editing). But in reality, there is a very large amount
of crossover. Your own situation is a perfect example.
