Play PAL movies at correct speed in VLC Apps
Have you been annoyed by PAL-encoded movies playing a little faster than usual, where the music's tempo is wrong and everyone talks a little faster?

If you have VLC, here's how to fix it:
  • Open VLC.
  • Go to the 'VLC' menu and select 'Preferences…'
  • In the radio buttons in the lower-left corner of the window, change 'Basic' to 'All'.
  • Click on 'Input / Codecs' in the left-hand side list.
  • In the right-hand side frame look for 'Playback speed' and change it to 0.96 (use a comma if your system uses that as the decimal separator).
  • Click on 'Audio' in the left-hand side list.
  • In the right-hand side frame disable 'Enable time stretching audio'.
  • Click the 'Save' button on the lower-right corner of the window.
  • Quit and relaunch VLC.
Enjoy your PAL movie at the correct speed!

Play PAL movies at correct speed in VLC

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 ;-)

It's the other way around. Euro electricity is 50Hz Pal is 25 FPS
US house current is 60Hz and NTSC is 30FPS

I never noticed the speed error, which means I don't watch many pal encoded film.

If VLC is made in Europe, why didn't the programmers see this right away????

D'oh!

Yes, you guys are obviously right and I was wrong. I had NTSC and PAL's framerates reversed.

Hey, at least I generated some discussion for this hint. :-)
