Hey Guys...
Looking at investing in a XH A1, and was wondering, the 24F mode that it has, and how it compares to say, the 24P mode of a DVX100. What are the similarities of the 24P of the DVX100? Or is it more of a "Cineframe 24" mode that sony introduced to give it a film "Feel" but really isnt true 24? Which of these does it more closley resemble? Thanks for any help!

Do a search. This horse has been beaten long after it's death. It certainly isn't "Cineframe"

24F *is* 24P.

Chris, I didn't see your title changed to disagreeable coot.

Love it.

Damn--the discussions over the difference between F and P are gonna go on forever, I guess. Canon shoulda used a P. It is 24 frames per second progressive, no interlace, no funky pulldown stutter motion. It is exactly the same as any of the other video cameras that also shoot real 24 frames per second progressive. The Z1's cineframe 24 is not the same thing.

Chris--maybe an automatic link to the Canon white paper about this could pop up any time there's an F used after the number 24 in any post?

In all honesty, there were qujestions about Canon's XL2 having "real" 24p, simply because people don't understand.

Bottom line is F is P and P is F, so just out and shoot some Preaking Frogressive video

:P

So after doing ALOT of searching, i've found that (and tell me if i'm right) that if i filmed with 24P with the DVX100 (since its one of the most used 24P prosumer cam) and 24F with the A1, the only difference is the HD? The film "feel" is there?

Film 'feel' is tough.

All 24p/f means is that it takes 24 full frames per second. This timing is exactly like film, so moving objects in the frame have the same motion cadence to them. They move in the same way.

That is all.

Everything else that makes film...filmy is more complex, like latitude, color matrix, etc.

Film has way more stops than any of these digital cameras. So they aren't exact replacements for film, but they're getting better. The A1 has more latitude than the DVX, and more resolution. I also believe (my opinion) that the A1's grain is more film-like, while the DVX's grain is very digital looking.

But 24p/f isn't everything that makes film...filmy. It is one necessary component though.

From what I understand, 24f and p is the same just as the others said. The only difference is how the frames are created. Other than that, enjoy.

Yes, it is. Now there are people backward and forwarding over which looks THE BEST but to my eyes the A1 is as good as any other. Too much banter in my opinion anyway. Better to be out shooting than arguing a cameras virtues. Its kind of like two guys standing on a street corner arguing over a chevy 350 and a ford 351 motor, both are quick engines, get in your damn cars and drive already.

Or, as Chris might say: Measurebating.
I think somebody needs to get that word into Wikipedia.

There are quite a number of Canon's 24p clips posted here that you can look at.
