That hole is standardized, same as for 35MM still film cameras. There
is often a second, smaller hole just ahead or behind the screw
threaded hole, this is for an anti-rotation pin. When you buy a tripod
witha quick-release plate, the plate is screwed into this hole, and
th elittle pin keeps the camera from shifting and turning on the
plate. The plate and comera conbination snapi and lock into place on
your tripod. If you want to quickly remove the camera for a hand-held
shot or something, you typically push a lever or other type of latch,
and the combined camera and plate detatch from the tripod. The plate
stays withthe camera the whole time. Be careful when shopping because
some plates are large than others and can make for a lot of
frustration if you have one of those stupidly-designed camcorders that
loads the tape from the underside. In those caes, you may have to pop
the unit off the tripod, then unscrew the plate from the camera, just
to load or unload a tape because the loading door doesn't clear the
plate.
BTW, tripods made for still cameras are often not a good choice for
video tripods: they are too wobbly for anything but astatic locked-
down shot, and thei cheap pan heads don't allow smooth panning with
control. For that you pay extra for a fluid head pan head. In the
broadcast business, typically a good set of sticks with a proper pan
head can cost as much as the camera itself.
