# Using the Audio Exporter

The Audio Exporter allows you write audio to separate .wav files. You can extract audio from whole sequences, shots, and source clips.

# Exporting Audio from Sequences

| 1. | Select a sequence in the bin view and navigate to File > Export...

The Export dialog displays.

| 2. | Select Process as Sequence from the Export dropdown and select a preset, duplicate it, and give it a name.

| 3. | Enter the Export To directory or click Choose... and browse to the location.

The Export To directory is the starting point from which the shot template builds your shot hierarchy.

| 4. | Build a custom shot template using Path tokens and the folder and +/- buttons and then click the Content field and select Audio Export from the list.

An example shot template is shown below:

| 5. | Click the Audio Export field and select the required export options, including the Output Channels for multi-channel audio.

| 6. | Set the Version number for the export, if applicable. Use the arrows to increment the version number and the +/- buttons to increase or decrease the padding. You can also type directly into the numeric field.

Note: See Using Versions for more information on how versioning works in Hiero.

| 7. | Select Tracks for this export by enabling or disabling the tracks in the list. Hiero exports all tracks by default.

| 8. | Set the Range controls as required:

• Select Whole Sequence or In/Out Points to export only the selected frames.

• Set how clip Start Frames are derived using the dropdown menu:

• Sequence - use the sequence’s start frame.

• Custom - specify a start frame for all clips using the field to the right.

| 9. | Set how Hiero should render your export using the Render with dropdown. Hiero provides the following options:

• Frame Server - uses multiple Nuke processes to speed up render times, improving resource management.

See Using the Frame Server on Render Machines for more information.

• Single Render Process - uses a single Nuke process to render your export. Rendering QuickTimes falls back to this setting, but it's also used when a problem is detected with the Frame Server.

• Custom Render Process - uses a custom render process. Hiero requires a Python script to pass exports to your render farm of choice. Scripts must be located in specific directories, dependent on platform, as listed in the Nuke Online Help. If no scripts exist, the dropdown only contains the default render processes.

| 10. | Click Export.

The Export Queue window displays an estimate of how long each component of the export is expected to take.

Once the export is complete, the file structure specified in the shot template is created.

Tip: Click the magnifying glass icon to reveal the exported file in a browser window.

• Set how clip Start Frames are derived using the dropdown menu:

• Sequence - use the sequence’s start frame.

• Custom - specify a start frame for all clips using the field to the right.

| 10. | If you're exporting shots, set the Handles controls as required:

• Clip Length - exports the full clip length available, as if the clip was opened as a Viewer.

• Cut Length - exports only the cuts included on the timeline.

Note: Selecting Cut Length allows you to add handles to each clip, up to the maximum available source clip length.

| 11. | Set how clip Start Frames are derived using the dropdown menu:

• Source - use the source clip’s start frame.

• Custom - specify a start frame for all clips using the field to the right.

| 12. | Set how Hiero should render your export using the Render with dropdown. Hiero provides the following options:
