New Features in DVD Studio Pro 4.2
DVD Studio Pro 4.2 adds several new features. For the latest information about this release, choose Help > Release Notes.
Support for Soundtrack Pro Audio File Projects
DVD Studio Pro now supports importing two-channel Soundtrack Pro audio file projects (STAP files).
Note: If you import a STAP file that includes more than two channels, DVD Studio Pro only uses the left and right channels.
Supporting Soundtrack Pro audio file projects makes it easy to take advantage of the powerful features of the Soundtrack Pro Waveform Editor to nondestructively modify the original audio source file.
You can import and use STAP files in your DVD Studio Pro projects like any other audio files. When you need to make a change to a STAP file, it will open in Soundtrack Pro.
Once you save the project in Soundtrack Pro, it will automatically update in
DVD Studio Pro.
To make a change to a STAP file from a DVD Studio Pro project:
1 Do one of the following to open the STAP file in Soundtrack Pro:
 Select the file in the Assets tab, then choose File > Asset > Open In Editor.
 Control-click the file in the Assets tab, then choose Open In Editor from the shortcut menu.
Soundtrack Pro opens with this STAP file in its Waveform Editor.
2 Make the needed changes to the STAP file in Soundtrack Pro and save the project.
3 Switch back to DVD Studio Pro.
The Asset Refresh dialog appears letting you know that the STAP file has changed. You can click Show Log in the dialog to see a list of elements that use this file.

Native Support for Additional H.264 Formats
DVD Studio Pro can now natively import additional H.264 high definition (HD) video formats. These assets are not reencoded using the embedded MPEG encoder.
The specific formats supported are:
 720p at 23.98 fps and 720p at 29.97 fps: You can now import H.264 assets with these frame rates into NTSC HD projects. DVD Studio Pro adds frame-doubling flags during the compile process to make them conform to the HD DVD specification.
Note: 720p at 59.94 fps H.264 assets were already supported in NTSC HD projects.
Important: 720p at 24 fps (not 23.98 fps) and 30 fps (not 29.97 fps) are not native and will be encoded. Additionally, 720p at 23.98 fps and 720p at 29.97 fps HDV formats are not native and will be encoded.
 720p at 25 fps: You can now import H.264 assets with this frame rate into PAL HD
projects. DVD Studio Pro adds frame-doubling flags during the compile process to make them conform to the HD DVD specification.
Note: 720p at 50 fps H.264 assets were already supported in PAL HD projects.
Important: The 720p at 25 fps HDV format is not native and will be encoded.
