Why if it is a TRUE 24p camcorder should vertical resolution be “reduced?”
Because, if the CCDs are truly running progressively, row-pair summation is turned-off thereby increasing V. rez.
If V. rez is reduced, then it may be running at 24fps, but is is not scannning progressively.
EZ way to tell. A 24p camera will have about 1/2-stop less sensitivity than 60i. (1-stop, but also a slower shutter-speed) So is the 24p sensitivity lower or the same as 60i?
