It really because Europe have 50 Hz and US 60 Hz mains. And the TV standards were locked to this, i.e. PAL (european colour TV standard) uses 50 Hz and US NTSC uses 60 Hz ( or really half as the pictures are interlaced for both systems)
Cinema has been using 24 Hz frame rate for ages...

Can someone point to an explanation of the logic behind the different frame rates:
I mean why is NTSC has 30 fps and 24 fps, while PAL is 24 fps and 25 fps?

The file I downloaded from the Canon site is an .exe file and I've attached the error message I get when I try to extract it. I've done a search on the computer and the .fir file is nowhere to be found. Any ideas on how to proceed?
You could create a new folder, and copy the file you downloaded from Canon' site to there. Then, you could extract it to the same folder.
Downloaded the new firmware but it will not extract. Tried on 2 different computers with the same results. The download is very slow and then speeds up. I will try again later in hopes the results will be different.

richierich1212: It's not just the frame rate. The film look is comprised of a few different things, those being the DOF of a full frame sensor, the frame rate, and the shutter speed at which film is captured, which for film is about 1/48th (or about half the time of the shutter.. the other half was used to transport the film to the next frame). By using that 1/48th exposure time for each frame of a film, the motion blur and movement was more fluid.
What most people don't notice is that video cameras will bump up shutter speeds in order to adjust for daylight or incoming light. By doing that, the time between each frame is longer, and the captured frame itself is sharper because it's a shorter duration.
So, if you start shooting with that 5D at 23.976, try giving 1/50th shutter speed a shot.
BTW, Gladiator bucked this trend and used a 1/192nd second exposure time, which made the fight scenes look very crisp and worked especially well with the moving blades and weapons.

I am going to make a guess that both have 24 fps because both TV broadcast standards would like to shoot film @ 24 fps, but NTSC has a native frame rate of 29.97 fps, whereas PAL has a native frame rate of 25 fps.
what i do find strange though is that they shifted 30 to 29.97 etc. but then why not 24 as 24 but 23.something? aren't movies truly 24.00000000000000000000

23.976 fps is more easily converted to NTSC 29.97 fps. I believe 23.976 fps is a very common frame rate, as "the look" is the same as 24.0 fps, but the math works out better for converting to NTSC (standard def. TV format).
Is the .fir just the firmware file specifically? Getting frustrated with the Canon site and not being able to download anything, including the new manual, etc.
Unsure if this has come up, but there's sound recording issues with C modes - when shooting in Av, Tv, or M and going into C1/2/3 sound recording is fine, but from starting the camera in C, sound isn't recorded but the monitors do appear (and appear to be working). Clicky here for more

Was able to download the new manual by going to Canon's USA website and drilling down the 5D2. Never could successfully download from the firmware site at the beginning of this thread.
Maybe I'm just imagining it, who knows, but I'm liking the 24p look. Played around with it a little yesterday and it's hard to pin-point, but I'd say it adds a unique look to the footage.
