It will shoot at 26 fps and record it in a 24p fps stream.

thanks David! so if i am not mistaken whatever i set the scene file frame rate to, it will shoot that frame rate and playback at 24p? this also means my editor should be set to edit in 24p right?
sorry about this, i have read Barry's book and use it as a constant reference. at the moment it is a lot of info to soak in. i am practising with the camera at the same time i am on this forum and find it very useful when i have questions about the book. it just reassures how i execute shooting!

If you're shooting in the 24pN mode, it will shoot at 26 fps and record as 24 fps files. Your editor would then edit as 24p, yes.

Yes, but let's clarify something else too: if you have it in 24pN mode, then what David described is correct -- it'll image at 26fps, record it into a 24fps stream, and your footage would come in at a very, very slight slow motion with no audio.
But if you were using 720/24P mode, then what gets recorded is a 60p data stream with 26 unique frames per second. Audio would be recorded, and the footage would play back in real time.
It makes a huge difference to the look of your footage as to whether you chose 720/24pN mode, or 720/24P mode.

In "over 60" modes (720/24p, 720/25p, 720/30p, 720/60p) audio is always recorded and always in sync. And the footage always plays back in "real time", regardless of the frame rate.
If you extract the duplicate frames to turn it into a pN-type file, you'll then get slow-mo or fast-mo, and then your audio won't sync anymore.

ok, i have another question concerning all of this p and pn stuff: i will be overcranking a very long shot hand held without the possibility of using the live capture to a laptop. that is the reason for using the pN with the P2.
now my question is, is it better to just keep all my footage in the pN mode to keep the style of the shoot consistent? or can i use the P2 in PN mode, then switch over to the 24p mode and do a live capture on the 60p stream for the same project (i.e. different scenes in a short film) without noticing a difference in the style?
maybe i am being overly worried here, but i am new and do not really have a lot of time to do a long enough test to make sure so i figured why not keep everything in pN mode.

Shoot 24pN with 60fps for slow motion and no sound and 24pN with a 24fps setting for the rest.
