Format Options Tab - Audio Settings

 
 
 

Audio File Type: For streaming formats, like QuickTime and MXF, the Audio File Type menu is automatically set to the Video File Type. There may be situations in which you require a separate audio stream. For example, if you export the video stream as a DPX file sequence, you can select a standalone audio file format (.aiff, .wav, .mp3, etc.).

The supported standalone audio formats are:

Compression:Use to select the audio compression settings. Options are:

For QuickTime: (Only 16-bit is available. There are no options in the UI.)

For MXF:

Sampling: Use to define the sampling frequency of exported audio files. Options are:

Lustre's behavior when exporting audio depends on the type of render mode selected. To export media files with audio, Lustre uses the grade-based audio file when the Media Origin is set to OneSequence. If you select Source Grade or Original Media and you are working with media files that contain audio media, such as Quicktime, MXF, R3D, the exported audio will come from the source media files.

Summary:

Note
  • You must select an audio output format that supports the number of audio channels you are exporting. For example, if you are exporting a four channel audio file to mp3, channels 3 and 4 will be discarded during the encoding as the mp3 format only supports up to two channels.
  • When exporting audio, Lustre will re-encode to the bit depth of either your source audio or your timeline audio, based on your export mode, as long as the selected output format supports that bit depth. If it does not support the bit depth, the export defaults to a lower bit depth, supported by the selected output format.
