Need info on 25p (PAL version)

I have a PAL version of the DVX100A.

Could someone please explain how the 25 fps is preserved, when a friend of mine says that everything is converted to 30 fps when shown on TV.


It confuses me.
 
Correct. PAL is 50 fields per second (also known as 25 "frames" per second, but that's a misnomer). NTSC is 60 fields per second (or 30 "frames").

The PAL camera shoots either 50 fields per second, or 25 frames per second.
 
OK thanks.

But does TV broadcasting have a specific frames per second that it broadcasts its programs? i.e if the broadcast standard was 50i, then how would my 25p footage look when broadcasted?

cheers
 
It will look progressive. It doesn't matter how your footage is displayed, it matters howit's captured. If it is captured prof=gressive, even if it is displayed interlaced, it will keep the progressive look. BTW, the progressive footage is layed on tape as"interlaced" in order to preserve the DV standard. When I say layed interlaced, I mean how the TV lines are recorded. What comes from CCD is important and actually gives you the look - progressive or interlaced. Following the same logic, if you print to film (which is a progressive output media) some interlaced footage, you will get exactly that - interlaced look.
