Watching "Shine A Light" for the first time on my computer tonight (three times in cinema before) ... I think it is the best concert movie of the Rolling Stones beside "Gimme Shelter" and "Voodoo Lounge (in Miami)" ... what do you think???

Movies are projected in the theatre at the well-known rate of 24 film frames per second. The PAL TV system (used in Europe, Australia and other places) projects images at a rate of 25 film frames per second. A problem thus arises when attempting to transfer a movie (24 fps) to PAL video (25 fps). The way this is normally done is to simply display 25 images from the film every second. That is, 25 frames from the film are being shown during a time interval within which 24 frames were supposed to be shown. The film is thus being projected 4% faster than intended by the director (25/24 = 1.04).
The most obvious effect of this speedup is that the film as viewed on PAL video (VHS or DVD) has a running time 4% shorter than it had when projected in the theatre, and 4 % shorter than what is specified in the Internet Movie Database. Take as a not-so-random example Béla Tarr's spectacular Sátántangó, a 450 minute film. A hypothetical future release by a European company would produce a DVD that is a mere 431 minutes — almost 20 minutes too short. Great if you are in a hurry, but most of us would probably feel ripped off. Let us hope that a future North American release is not based on a PAL master.
There is another effect associated with this speedup, an effect that is especially obvious to those with a well-developed musical ear: viz., the audio track of the film is playing 4% too fast, and thus 4% higher in pitch. From music theory we recall that one semitone in equal temperament is exactly 1/12 of the octave, i.e., 1/12 of doubling the frequency, i.e., the 12th root of 2, which is 2^(1/12) = 1.06, a result that is very close to the PAL speedup (1.04). In musical terms, PAL speedup therefore corresponds to a rise in pitch of a bit less than one semitone (or, 0.706724268642822855 semitones, to be precise).

NTSC has its own problems, to be sure, but thanks to its 30 fps frame rate, combined with the 3:2 pulldown scheme, it is capable of reproducing the correct film speed of almost exactly 24 frames per second. Thus, native NTSC transfers form an excellent baseline for film speed comparisons. (To be entirely precise, the exact NTSC film frame rate is a tiny bit lower than 24 fps: it is 59.94/60*24 = 23.976 fps, an imperceptible slowdown. Our hypothetical Sátántangó NTSC DVD release hence lasts 27 seconds longer than it did in the theatre. Which, resolution advantages aside, in our mind is much preferable to the 20 minutes shorter PAL version.)
