But talk all you want the eye still has the limitations as I've said before.

And 60 Hz is used as that is the limit of human "shutterspeed", 1/60 s.

the velocity difference and length of burn time between a rounds tracer and a sparkler.



People need to keep in mind that a movie camera takes a "snapshot" every 1/25 of a second or so (depending on camera), so, if that camera is "shaking" (even minimally) it takes the "snapshot" at different aspects of the subject, hence the "zig-zagging" of guncam footage... both WWII and the more modern helicopter mounted GAU in the popular (in this thread) YouTube.
