Supported Asset Types

The Track Editor’s streams contain the video, audio, and subtitle assets. You can add one or more assets to each stream. Each stream has several properties you can set, such as its language and whether or not it is enabled.

See Creating Subtitles for information on working with the subtitle streams.

In addition to assets that are already DVD-compliant, you can add assets supported by the DVD Studio Pro integrated MPEG encoder. These assets are encoded once they are added to your project.

See Encoding Video Materials for DVD for information on supported video assets, Preparing Audio Assets for information on supported audio assets, and Using the Integrated MPEG Encoder for information on the assets the integrated MPEG encoder supports.

Video Assets for SD-Based DVD Video Streams

All video assets on an SD-based DVD stream must use the same aspect ratio (4:3 or 16:9), the same video standard (PAL or NTSC), and the same MPEG type (SIF MPEG-1 or full D1 MPEG-2, for example).

Note: All QuickTime video assets you import into an SD project are encoded as full D1 MPEG-2 assets and can be mixed with still images in a video stream.

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 Using Still Clip Transitions 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.)

Using AAC Audio Files from the iTunes Store

DVD Studio Pro is able to import and use AAC format audio files purchased from the iTunes Store as long as the computer you are using them on is authorized to use them. If you import iTunes Store files that the computer is not authorized to use, DVD Studio Pro plays silence when it encounters those files. Additionally, if you select and try to play an iTunes Store file that the computer is not authorized to play in the Audio tab in the Palette, DVD Studio Pro plays silence.
