Another option would be to look into a Colorado Video Peak Store "gadget".
It detects and holds level changes in the image at video rates but it does not
preclude, I think, a double or triple "exposure" on a given frame. Just a
thought at this point. The larger problem with video is typically the low
resolution of the images but if you can work at high magnifications this may
not be a limitation.
For multi-position motion analysis on a single final frame this device has lots
of potential. It allows one to do what Doc Edgerton did for golf/tennis motion
studies with a stroboscope with a simple camcorder to capture the images at 60
fps (at exposure times of 1/10,000 second!), the peak store instrument and a
VCR to tape it all. Interesting thing is that the gadget is not a "cumulative"
decording peocess such as film and so multiple exposures of a stationary
subject do not cause overexposure!
You can see a sample of this type of motion analysis image on my webpage at:
