salty is talking about frame rate. It is a few posts above - "frame rate
(shutter speed)". ...

I know you don't mean that, just mis-written.

Of course I mean it.

salty said "All faux shutter speeds in a video camera are based on the
60 cycle standard." charlie said *shutter speeds* are not based on 60
cycles, which is correct. But salty is clearly referring to a *frame
rate*, which is based on "the 60 cycle standard".

The SHUTTER-SPEED is how LONG the shutter STAYS OPEN for a SINGLE picture.

If you take only one picture a year, your FRAME-RATE -- well, photo-taking
rate, maybe -- is ONE per YEAR, the "dimensional units" of that being
"photos / amount-of-time-taken-by-your-photo-taking", something like that.

A movie or video photographed or "taken" as above would be in VERY "SLOW-MOTION".

(That is, if you VIEWED it at eg 50 or 60 or whatever frames (pictures) per
second.)

Shutter-speed describes a SINGLE picture or frame -- if there's 5000
pictures or frames to be shown rapidly, one after the other, that
shutter-speed describes EACH SINGLE ONE (presumably).

Frame-rate is "independent" of (some say "orthogonal to") that --
hey, I'm out of words, what else can I say, huh?

Most of us know all that.
