But Aren’t DVDs Already High Definition?

In addition to traditional 4:3 aspect ratio video, traditional DVDs support widescreen
16:9 video, which is often mistaken for being high definition. The 16:9 video used on
current DVDs, however, is the same resolution as the 4:3 video, which is the same as
the standard NTSC and PAL broadcast resolutions. The 16:9 video must be anamorphic,
which makes it appear horizontally squashed when viewed on a 4:3 monitor.

This leads to a logical next question—what constitutes high definition video? While
most HD video formats use a 16:9 aspect ratio, what generally defines whether or not
they are HD is the resolution.

Video resolutions that result in more pixels per frame than are used in SD-based DVDs
are considered high definition. There are two common HD vertical resolutions: 720 lines
and 1080 lines (used for both NTSC and PAL). These compare to NTSC’s 480 lines and
PAL’s 576 lines for SD video.

As with SD-based DVDs, the scanning method used on HD-based DVDs can be interlaced,
with a video frame containing one field with the odd lines and another field with the
even lines, or progressive, where each frame is complete. Not all HD formats support
progressive scanning, however. See

Supported Video Resolutions

for details on supported

SD and HD video formats, including frame rates and scanning methods.

About DVD Studio Pro and HD Resolution DVDs

In addition to supporting standard definition (SD) format video DVDs, DVD Studio Pro
supports creating high definition (HD) format video DVDs.

With the exception of support for HD video resolutions and the number of buttons on
menus and button over video subtitles, HD projects in DVD Studio Pro have the same
limits as SD projects.

There are two aspects to creating DVDs with HD content: what you can put into the DVD
video zone and the DVD disc media.

DVD Video Zone with HD Content

While the contents of the DVD video zone for an HD-based DVD (HVDVD_TS) are similar
to those of an SD-based DVD video zone (VIDEO_TS), there are some important differences:

• HD-based DVDs support a broad range of video resolutions, including most of those

used in SD-based DVDs. See

Supported Video Resolutions

for a complete list of

supported resolutions.
