You shouldn't have to worry about exposure, since the best video is
more contrasty than pretty much any film stock.
To do this at 24fps rather than frame-by-frame, you'll not only have
issues with the short wind on the Bolex, but the fact that doesn't run
at constant/exact speed.
The only way I've ever done this myself is the old-school method,
using an Auricon with a Kinescope shutter off an old NTSC CRT TV set,
and I liked how it looked. Nowadays there are more options, with LCD
and Plasma video monitors (SD and HD) and computer displays (which may
have different refresh rates available). Each sort of video display
will generate a different look, and it kind of depends on what sort of
effect you want.
I would assume you could shoot an NTSC screen at 24fps with any camera
with a crystal motor and a variable shutter, if you can get the
shutter set correctly.
