QuickTime Audio Settings for Sequences
Final Cut Pro uses the built-in QuickTime architecture of Mac OS X for playback and export
of your sequence audio. When you export your sequence, these audio settings are used
by default.
Settings in the
General tab
• Sample Rate: Lower sample rates take less bandwidth but have lower quality. Make
sure your sample rate is compatible with the audio facility to which you’ll be handing
off the files. Usually, you use the sample rate specified in your sequence settings, which
should ideally be the sample rate of the original audio media files.
• 32 kHz: This corresponds to a consumer sample rate option on DV camcorders. Unless
you have a special reason to use it, avoid this sample rate for audio export.
• 44.1 kHz: This is the sample rate of music CDs and some DAT tapes.
• 48 kHz: DV formats and many professional video formats use this sample rate.
• 88.2 kHz: This is a high-resolution sample rate that can be easily converted to 44.1 kHz
audio files.
• 96 kHz: This is a high-resolution sample rate that can be easily converted to 48 kHz.
