Controlling Playback

Locating missing audio

6. In the property page, use the transport controls to position the tape in your external device to a

blank area for recording.

7. Close the property page, and click the Save button in the Export Video dialog to start exporting.

If you’re printing to a device that uses tape, the tape stops rolling when the export process is

finished.

Synchronizing external video playback to audio

Because there is more latency in FireWire video playback than in PC digital audio playback, video

playback on an external device will probably be playing back later than the audio tracks in SONAR.

To sync external video to audio

1. Right-click the Video view and choose Video Properties from the pop-up menu to open the

Video Properties dialog.

2. On the Render Quality tab of the dialog, under External DV Output, enter an offset number in

the Video Sync Offset field. The number you enter here causes the Video to start playing sooner

than the audio. It’s helpful if your video has some pre-roll footage that contains a visual sync point.

3. Click OK to close the dialog. Play your video, and readjust the Video Sync Offset number as

needed.

Locating missing audio

If you try to open a project and SONAR is unable to locate all the audio files that the project

references, the Find Missing Audio dialog appears. The Find Missing Audio dialog helps you find

any missing audio in your project.

The Find missing audio file dialog

Use the Locate Missing Audio File dialog to find missing audio in your project. The following is a

brief description of the options you have in this dialog:

• Open. Click this button once you have searched for and found the missing audio file.

• Skip. Click this button to move to the next missing file. When you skip and audio file your project

Note: The offset is accurate to 3 decimal places, e.g. 1 ms (a thousandth of a second). One

frame of video is approximately 33 ms long for NTSC and 40 ms for PAL; the offset will typically

be less than 1 second.
