how many frames....

[kk01]

hello guyz,

...I'd like to know how many frames do you have in one second, one minute, ...e.t.c. I'd like to know how many frames a scene will last for a particular time in the timeline...

and I guess different formats all have different timing...is this true...

regards,
'kk'

Its time for you to read "What is" and "How To" sections of this forum before we can proceed.

PAL it is 25 frames per second, or 50 fields per second.
NTSC is it 23.976 frames per second, or 29.976 frames per second, however it is played back at 29.976 frames per second, or almost 60 fields per second. These are the basics for broadcast and DVD. Digital may be different again.

Anything you find on the web could vary from as low as 12 fps or less, up to 50 fps or more.

You need to look at the frame rate of the video you have to be sure what you will get.

...thank you very much for the advice sanjayk and thanks for the info gunslinger...

emmm! but gunslinger you wrote this 'PAL it is 25 frames per second, or 50 fields per second'...what do you mean by 50 fields per second...

thanks...

sanjayk, I checked out the 'what is' and 'how to' links and I didnt find anything that help...or rather should I say they were not explanatory enough...

http://www.digitalfaq.com/dvdguides/capture/understandsource.htm might assist.

As I understand it, interlaced material has two fields - called "top" and "bottom". Top is lines 1,3,5 ...... and all the odd-numbered lines in the frame. Bottom is lines 2,4,6 ... and so on. When combined, these two fields form one complete frame.

As for how many frames in a second or whatever, simple maths gives you the answer.

25frames per second (PAL DVD standard) x 60 = 1500 frames per minute.
29.97frames per second (NTSC DVD standard) x 60 = 1798 frames per minute.

KK if you go to the "What is DVD" section and scroll down a bit you would get info like shown below which give you idea about frame rate (fps). however it does not talk about fields and other stuff. I suggest you could go through this link also besides what is suggested by Jim.
