24 @ 25
True 24 fps film or video can be transferred to PAL (25 fps) by speeding up the frame rate
by 4 percent. For film editing purposes on PAL video, applications like Cinema Tools can
slow the 25 fps PAL video back to 24 fps (a process called conforming) so that sync is
maintained with the original audio.
For showing film-originated movies on PAL video, both film and audio speed are
increased by 4 percent. The speed increase is considered acceptable, although the
audio must be “pitch shifted” down to match the original. This is the most common
method for film-to-PAL transfers.
