Video/Audio Tab
The Video/Audio tab contains two groups of controls: Video and Audio.
Video controls
This group of controls allows you to set your video output options.
Kind: Choose from QuickTime Movie, Still Image, or Image Sequence.
Note: Audio options are only available for QuickTime movies.
Compressor: Depending on the Kind setting, different compressor types are available.
Quality: For some compressors, you can set a quality setting. If the control is dimmed,
that compressor type does not offer variable quality.
Start number: For image sequences, you can set a starting frame number. Each file
generated in the image sequence has an incrementing number.
Add spaces: When generating image sequences, clicking the Add Spaces checkbox
causes extra spaces to be added to the filenames to ensure that the sequence of files is
read in proper order by some other applications.
Advanced: The Advanced button is only active for QuickTime movies. Clicking this
button opens the standard compression settings dialog. In most cases, you should not
need to make any changes in this dialog.
Audio controls
This group of controls allows you to set your audio output options.
Sample rate: Sets the audio sample rate for your exported movie. For best results, set
this to be the same sample rate as the source audio in your project.
Mix: Sets the audio output mix for your project. Use the default Stereo setting or
choose 5.1 Surround.
Advanced: The Advanced button opens the standard Sound Settings dialog. In most
cases, you should not need to make any changes in this dialog.
Output Tab
The Output tab contains the following controls:
Use current project and canvas settings: When this is checked, this setting overrides
the contents of this dialog with the current settings in your project. This allows one
export preset to be used with multiple project presets. When this setting is turned off,
you can create specific settings for the export preset.
