Well, I had given up the webcam idea after your first response!
My second response was intended along the lines of multiple camcorders.
And, by "permanent", I didn't mean "bolted down to the floor", just that all
the filming/production would be in one studio space, not going from location
to location.
After to talking to B&H this morning, the multiple camcorder idea does seem
to be impractical.
Don't really understand *why* it's so impractical, but I'm in no position to
be a maverick here. :)
B&H basically said, if you have $10K, go pro (and stay traditional!).
If you want to get by for well under $5K, go consumer. But still use
mini-DV tape, as you suggested.
So, they recommended a $500 Sony that is good in low light, maybe an $800
Panasonic, that would give nice results for what I need right now.
Any specific camera recs/comments here would be appreciated.
Any user-friendly editing systems, for basic stuff?
AVSmedia claims their editing package is super-user friendly, and offer a
"super-bundle" of products at http://www.avsmedia.com/.
Good bundle? Good way to get started? Other suggestions?
Oh, btw, my little operation here is a bit more than "hand machining in a
basement".
The equipment I have (both CNC and manual), in about 1200 sq ft, is more
than capable of putting out 100's of units a week, altho I'm the first to
admit that this proly isn't the smartest way to go.
But I will have no choice but to do the first few hundred myself, before I
farm it out to professional production shops.
In the same vein, I need to set up a basic video operation, to get the
overall "direction" correct, and then I'd be more than happy to let
professionals set up an efficient studio and produce a professional product.
I'm hoping the 5-600 sq ft studio space, which will house the editing
operation as well (altho that could be moved), will be sufficient.
Right now, I'm producing beta versions of the unit, but which still need
dvds, as the method of using the hardware/apparatus is as important as the
apparatus itself.
No looming deadline, just the sooner the better.
It will indeed be ongoing video production, as the apparatus has so many
extensive uses, which vary with the niche: Professional/ballet dancers,
athletes, simple fitness/weightloss (which actually is not so simple,
mis-infomercials notwithstanding), joint rehab, back rehab, sports-specific
applications, etc.
Looking forward to getting the video part up and running. Appreciate the
feedback and guidance.
