Apple DVD Studio Pro 4 - Manual (Page 147)

To convert an SD project to an HD project
1 Do one of the following:
• Select the project’s name (next to the disc icon) in the Outline tab.
• Click an empty area in the Graphical tab.
The Disc Inspector appears. (Choose Window > Outline if the Outline tab is not visible.
Choose View > Show Inspector if the Inspector is not visible.)
2 Click the General tab in the Disc Inspector.
3 Select the HD DVD setting for DVD Standard.
A warning appears stating that you will not be able to convert the project back to the
SD DVD standard.
4 Save the project using a new project name.
This ensures the original SD project will remain as it is and not be overwritten.
There are a few things to keep in mind when converting an SD project to an HD project:
• HD projects cannot have MPEG-1 video.
• When you import QuickTime HD assets into an SD project, DVD Studio Pro automatically
creates an SD MPEG-2 format version of them using its integrated MPEG encoder. If
you then convert the project to an HD project, the HD project continues to use these
SD MPEG-2 assets.
You can have the integrated MPEG encoder create MPEG-2 HD versions of those assets
by Control-clicking them, choosing Encoder Settings from the shortcut menu, and then
choosing new encoder settings for the asset.
Once the assets have been reencoded, you can change the resolution of any elements
that use them, such as menus or tracks, to match their new HD format.
Note: If you choose a new bit rate when reencoding an asset to an HD format, the
original SD-encoded asset remains available for use by the SD project. If you do not
choose a new bit rate, the SD-encoded asset may be overwritten by the HD-encoded
asset.
• If your SD project contains QuickTime video assets that use an HD video resolution,
you can have the integrated MPEG encoder create MPEG-2 HD versions of those assets
by Control-clicking them, choosing Encoder Settings from the shortcut menu, and then
choosing new encoder settings for the asset.
