Hi all,
is there a way in linux to tell if a DVD is NTSC or PAL?
Thanks!
George

I believe mplayer will tell you if the vob files are ntsc or pal. I don't think linux itself can tell you, DVD's use vob files for movies.

i used ifo_dump_dvdread
for example:
| Code: |
ifo_dump_dvdread /dev/dvd 1 | grep ntsc
ifo_dump_dvdread /dev/dvd 1 | grep pal
ifo_dump_dvdread dvd-image.iso 1 | grep ntsc
ifo_dump_dvdread dvd-image.img 1 | grep ntsc
ifo_dump_dvdread VIDEO_TS/ 1 | grep ntsc
|
it reads out of just about anything  awesome tool |

I thought DVDs are not coded in NTSC or PAL? The mpeg2 format does not have that difference? |

| I believe PAL and NTSC have different resolutions, and PAL works at 24fps while NTSC works at 30fps... |

Thats correct (PAL is actually 25fps) but that doesnt mean it's actually coded differenty on the DVD. Thats just how it is sent from the player to the TV. I can watch a U.S. DVD here on my European player and don't see any difference. (Once the player's region code is overridden). |

Press Ctrl+I during playback to display stream/DVD information. The second line down will show the resolution of the picture.
Pay attention to the second number (vertical resolution). If its 720x576 then it's PAL, if its 720x480 then it's NTSC. |

| so then does the PAL version chop off some of the left and right side of the movie? Since NTSC and PAL have the same width, but PAL has a greater height, either PAL cuts off the left and the right, or NTSC cuts off some of the top and the bottom... which is the correct answer? |

They are actually coded differently. Your DVD player/TV are able to show both content and/or scale them properly

They both might have ~same picture with the same aspect ratio. PAL just has more resolution. PAL dvd is not, thank god, made from NTSC dvd but from the source material. BTW: pixels are not square in anamorphic DVD.

IMHO. Unless a DVD is poorly authored or it is interlaced PAL, which is terrible. Usually PAL DVDs are progressive. One other advantage is that in PAL format bad movies do not last as long as in NTSC format.  |
