Film runs at 24 frames per second. PAL TVs refresh at 50Hz (50 fields per second). To make a film compatible with the PAL format it is sped up to 25 frames per second.Also, could someone explain the reason for the audio running fast?

(NTSC TVs refresh at 59.94Hz. To show a film on an NTSC TV it is telecined with 3:2 pulldown which equates to a framerate of 23.976fps. To convert audio from a PAL source for use with an NTSC source it therefore needs to be slowed down by 4.096%.)
