About Segmented MPEG Files
The segmented MPEG files created by some third-party encoders do not import correctly
into DVD Studio Pro. Some encoders segment their large encoded files into 1 GB files.
When imported into DVD Studio Pro, only the first 1 GB segment is imported. You need
to combine the files into a single file before importing the asset into DVD Studio Pro.
There are several third-party applications that can be used to combine a segmented
MPEG file into a single file.
Video Assets for HD-Based DVD Video Streams
All assets on an HD-based DVD stream must use the same aspect ratio (4:3 or 16:9), the
same resolution, the same video standard (PAL or NTSC), and the same MPEG type
(MPEG-2/HDV or H.264).
All non-HDV and non-H.264 QuickTime video assets you import into an HD projects are
encoded as MPEG-2.
Note: Because HDV is actually HD MPEG-2, you can combine HDV assets with other HD
MPEG-2 assets, including those encoded from the integrated MPEG encoder, as long as
they are the same resolution.
Still Assets for Video Streams
You can add still images to a video stream to either manually create a slideshow or create
a stream with mixed motion and still video. Stills can be added to all SD and HD tracks
except those using SIF, 1/2 D1, cropped D1 MPEG-2, or H.264 format assets.
Still asset clips in a stream must each be at least 15 frames long for NTSC projects, or
12 frames long for PAL projects.
Note: To have still assets with shorter durations, you can edit them into a video asset
using an external video editor.
Still clips can have a transition added to their end. The transition controls what happens
at the end of the still clip—for example, you can configure it to dissolve or wipe to the
next clip, whether the next clip is a video or still clip. See
for
more information.
Assets for Audio Streams
All audio assets within a stream must be the same type (AC-3, AIFF, MPEG-1 layer 2, and
so on) with the same number of bits (16, 20, or 24), the same sample rate (48 kHz or
96 kHz), the same bit rate (when using compressed audio), and the same channel
configuration; for example, stereo or 5.1 surround. (The streams within a track do not
have to match each other—only the assets within a stream must match. For example,
the A1 stream can use AC-3 audio and the A2 stream can use AIFF audio.)
