Question about the different frame rates

[00Nader00]

Hey guys, I was reading the HVX book by Barry Green and I was confused about a couple of things.

First of all, he mentions that you can shoot in over 20 different frame rates, but what is the point of being able to shoot in 1,4,8 frame rates?

I know that it just creates a "style" or look, but i dont understand when someone would use 1 frame rate.

The second thing I am confused about is the "Loop record" format.

I understand that it records when you dont press record and then if you press record it will record up to however amount of time your p2 card has but then, does it record over the stuff you didnt press record for? I know it sounds confusing so let me try to simplify it:

if I have a 64 GB p2 card and am recording in high def at 720p/24pn. This has an approximate recording time of 148 minutes. So if i loop record for 100 minutes and the press record and record for another 100 minutes then does it just record over the first 48 minutes of the pre-recorded thing I taped?

anyway sorry if I sound confused/confusing, I am just scratching my head over it.

thanks for any help,

Nader

The various frame rates are all there because they provide different "looks".

As for loop record - if you have 148 minutes of recording time on your cards, and record a 100 minute clip, it will be a 100 minute clip on your cards. Your cards will now have 48 minutes of recording trime available. If you record for 100 minutes, it will record normally for the first 48 minutes, and then it will "loop" back to the beginning of this clip, overwriting what has been recorded, until you press stop. The net result is that the last 48 minutes will have been recorded. And at that point, your cards will be full and you can't record anymore.
