Apple DVD Studio Pro 4 - Manual (Page 76)

Important: When calculating the combined bit rate for a track, you only need to add in
the bit rate of one video stream, but it needs to be the stream with the highest bit rate.
SD Projects
• 5 angles or fewer: 8 Mbps maximum for the track’s combined bit rate
• 6–8 angles: 7.5 Mbps maximum for the track’s combined bit rate
• 9 angles: 7 Mbps maximum for the track’s combined bit rate
HD Projects
• 2 to 9 angles: 24 Mbps maximum for the track’s combined bit rate
Note: 1080i HDV video uses a bit rate of 25 Mbps, which is higher than the maximum
allowable multi-angle bit rate. 720p HDV video uses a bit rate of 19 Mbps, which,
depending on the number and type of audio and subtitle streams, can be used in a
multi-angle project.
Adding Markers to Your Video
You can add markers to your tracks in the DVD Studio Pro Track Editor. You can use these
markers in a variety of ways—the most common usage is to provide a place in a track to
which a button on a chapter index menu can connect.
Apple video editing applications—Final Cut Pro and Final Cut Express—let you add
markers while you edit the video. You can also add markers with Compressor. There are
two types of markers that are important to DVD Studio Pro:
• Chapter markers: DVD Studio Pro can import these markers and display them in the
Track Editor.
• Compression markers: The integrated MPEG encoder uses these markers to place custom
I-frames in the MPEG-encoded file.
Because DVD Studio Pro can import chapter markers added within Final Cut Pro,
Final Cut Express, and Compressor, you can choose to create the markers in the editing,
compressing, or DVD authoring process. When you import video with chapter markers
into DVD Studio Pro, you see the marker position and marker name you set appear in the
Track Editor. The markers can then be edited within DVD Studio Pro exactly as if you had
manually created them there.
Note: The markers embedded in MPEG files encoded with the DVD Studio Pro 4 version
of the integrated MPEG encoder are not compatible with 1.X versions of DVD Studio Pro.
Placing Chapter Markers Exactly Where You Want Them
Adding markers in Final Cut Pro, Final Cut Express, or Compressor offers the potentially
large advantage of allowing you to position them on the exact frame where you want
them to appear.
