Play PAL movies at correct speed in VLC
Authored by: Blake on Sep 15, '10 09:44:00AM

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.
