Apple Final Cut Pro 7 - Manual (Page 1877)

• Depth: Choose the bit depth used for each sample.
• 8-bit: This bit depth is useful for highly compressed movies created for the web.
Unless you have a specific need for 8-bit audio, you should avoid this option because
the quality is fairly low.
• 16-bit: This is the bit depth of DV, DVCAM, and DVCPRO, as well as of music CDs. If
all of your original audio media is 16-bit, and you aren’t routing multiple audio tracks
to the same audio output, choose this option.
• 24-bit: A high-resolution bit depth compatible with many third-party video and audio
interfaces. Choose this option to preserve the highest possible quality when exporting
your files, especially when some of your audio files are 24-bit, or when you are mixing
multiple audio channels together by routing them to the same output channel.
• Config: This pop-up menu works in combination with the Downmix control in the
Audio Mixer to determine how the Export QuickTime Movie command groups your
sequence audio outputs during export. There are three options:
• Stereo Downmix: This option exports a stereo mix to a single stereo QuickTime audio
track and overrides the Downmix button in the Audio Mixer.
• Channel Grouped: Based on your sequence’s audio output groupings, multiple stereo
and mono output busses are exported to corresponding stereo and mono QuickTime
tracks.
• Discrete Channels: This option exports channels in the same way as the Channel
Grouped option, but each channel in the QuickTime movie audio track is labeled as
a discrete channel, numbered according to the audio output bus that the channel
is assigned in your sequence. Use this option when you want to preserve your
sequence’s original audio output assignments in your exported QuickTime file.
Video Processing Tab for Sequences
You can change color space and motion transformation rendering options in the Video
Processing tab of the Sequence Settings window. For new sequences, you can change
default settings in the Video Processing tab of the appropriate sequence preset. For
detailed information about the settings in the Video Processing tab, see
“Rendering and
Video Processing Settings.”
Timeline Display, Render, and Audio Output Options
When you create a new sequence, the Timeline display, render, and audio output settings
that are used come from the corresponding tabs in the User Preferences window. Once
a sequence is created, you can change its options by selecting the sequence and choosing
Sequence > Settings.
