Play PAL movies at correct speed in VLC
Authored by: leamanc on Sep 15, '10 08:41:09AM

It should go without saying, but make sure to set it back to 1 when watching NTSC encoded movies after that.

Checking out the Wiki pages for PAL and NTSC should provide enough background for those who don't know what this means, but basically PAL TV runs at 29 frames (and some change) per second, while the NTSC standard (used in the USA) runs at 25.

Actually, you've got it backwards: The NTSC standard is 29.97 fps, and PAL is 25 fps. And if this hint is talking about what I assume it is, not all PAL videos are affected, and it has nothing directly to do with VLC (although the workaround here should work, in principle). The problem is that theatrical movies are normally filmed at 24 fps, not 25 or 30. A process called 3:2 pulldown (too lengthy to go into the details here) converts such movies to the nearly 30 fps rate required on NTSC systems, and the playback speed ends up very close to the original. On PAL systems, the common approach is to simply speed up the movie from 24 to 25 fps, shortening the playback time. Sometimes the soundtrack is processed to prevent the sound from raising in pitch, but that varies with the movie.

I think you meant to say that PAL is 25 and NTSC is 29.97 for their frame rate.

Maybe you should go back and read some more PAL = 25 fps and NTSC is ca. 29.97 fps - you wrote the reverse ;-)
