I thought ntsc is 30p and pal 25p but 24p ? isnt it independent of both the systems? af100 is a motion picture cam and we use 24p for film like motion.
You're right. Film is shot at 24 fps and it doesn't strictly speaking have anything at all to do with NTSC or PAL since celluloid was neither. Since this is a video camera, however, it allows you to shoot at many different frame rates so you can fit in with whatever your delivery requirement (or artistic vision) is.
So the short answer is if you need 24 fps, you need to turn the camera to NTSC mode, as that's where the 24 fps option lives in the menu structure. It will not be shooting either NTSC or PAL, but high definition video at 24 frames per second, which is probably what you need. If you need 25 fps, turn it to PAL. If you need 29.97, turn it to NTSC and turn off the 24 fps option.
All versions of the AF100 sold in different countries can shoot all those framerates, you just need to set it to the appropriate mode first.
As others have said, if you want a film-like aesthetic but you are in a PAL country, and you have no requirement for exactly 24 fps (eg matching celluloid or projection at 24 fps) you may be better off shooting at 25 fps, as the look is indistinguishable but it makes life easier for viewing on PAL-based equipment.

You can Shoot at 24P by switching the Camera to it's NTSC setting - in the Menu go to OTHER FUNCTIONS, then SYSTEM FREQUENCY and switch to 59.94Hz.
You will need to set up your Edit Software accordingly to keep any effect gained - you will need to set the input and output to cope with the 24fps otherwise if you just edit at 25fps and output at 25fps the effect will be lost and your Sound will be sped up.
Also, if your going to record Sound on a separate system from the Camera, make sure you emphasise to the Sound Recordist that you are Shooting at 24fps.
As mentioned in this thread - most people wouldn't notice the difference.
24P (and having the Camera at 59.94Hz) does also give you access to some frame rates not available in 25P (50Hz).

Thanks Hywel, thanks Neil. I was( am ) under the impression that 24p creates filmlike motion. If I cange to ntsc mode and set to 24 fps, footage will get a flicker because of change in Htz.
isn't it?
isn't it?

Change the shutter angle to 179.2* if you need to shoot 24P with 50 Hz lighting.
If all your light is provided by Kino-Flos, or HMIs with electronic ballast, then there's no need to change the shutter angle.

The flicker isn't directly from the change in Hz but from showing 24fps on PAL medium - Pal TV or other 25fps device, your output master from your Edit will be in PAL, 25fps, so you're kind of introducing a pull down into the mix if you want to keep the 24p thing and show at 25fps - (and yeah I know all about the 50 fields, etc.).
- As far as I understand. Have looked into this extensively in the past but I'm not referring to my notes here.
If you're in the UK, or even Europe, the best method you can possibly use here to make sure it all goes smoothly is to employ me to Shoot it!
- Offers of work welcome.
Otherwise, if you're in the UK PM me for contact details, and I'll be happy to talk you through it.
Cheers,
Neil.

I would highly recommend to shoot 25 p in PAListan and countries that have a 50Hz frequency of their electrical grid. You may run in a lot of problems going 24 p without really gaining anything. But it depends much on where to and how you want to put out your material.
About flicker and how to avoid it a very helpful link:

film in PAL land is 24fps and always has been.

Definitely. Film speeds are totally irrelevant of Hz, they preceded NTSC and PAL, etc.
Having Video at 24P in 'PAL Land' is kind of introducing an anomaly to get a pseudo Film Look/Effect - which you may want and like.
The majority of Feature Films Shot at 24fps transferred to DVD, BlueRay, Shown on TV, etc., in 'PAL Land' will be sped up to 25fps, to fit the PAL speed. The Audio is usually adjusted so that it's pitch is not changed. Check it out, the running time given on PAL DVDs, etc., will be several seconds less than the Theatrical version due to this increase in fps. - Some more recent PAL copies, TVs and DVD Players, etc., have a 24P option to try and keep closer to the Theatrical versions and keep that more obvious Film flicker.
