Setting the video input standard
The video input standard determines how the Apple Video
Player application interprets video signals. This standard is
preset to your region in the Apple Video Player software. In
most cases, you won’t need to change it.
NTSC is the standard video signal for most of the Americas
and Japan. PAL is common in Western Europe, Australia,
most of Asia, and parts of South America and Africa. SECAM
is used in France, Eastern Europe, and parts of Asia and
Africa.
To change the video input standard, follow these steps:
1 Choose Preferences from the Setup menu.
The Preferences dialog box appears.
2 Choose the Video Input Standard setting you need.
If the setting you choose produces a strange image (for
example, the picture is too small or the colors are odd), try
another setting.
