Setting the Video Standard
The DVD-Video specification supports two video standards: NTSC and PAL. This may
appear to leave out those countries that use the SECAM or PAL-M video standards.
However, because the MPEG video on DVDs is in a component format, your sources, once
MPEG-encoded, only need to conform to the line and frame rates of either the NTSC or
PAL standard.
• Use the NTSC video standard: If you are in a country that supports either the NTSC or
PAL-M video standard. Both standards use a 29.97 fps frame rate with 525 lines per
frame. As a general rule, if your country uses 60 Hz AC power, you should use the NTSC
video standard.
• Use the PAL video standard: If you are in a country that supports either the PAL or SECAM
video standard. Both standards use a 25 fps frame rate with 625 lines per frame. As a
general rule, if your country uses 50 Hz AC power, you should use the PAL video
standard.
See Video Standards of the World for a list of countries and the video standards they
support.
You cannot mix NTSC and PAL assets on a DVD. See NTSC or PAL? for more information.
Also see Changing a Project’s Video Standard for information on converting a project
from one video standard to the other.
Important: If you have any doubts about whether your system is set to the correct
standard, you should verify its setting (described next) and change it if necessary before
you start adding assets to your project.
