Exporting video
After you’ve mixed your audio tracks the way you want them, you can export the inserted video file
together with your audio tracks to create a new video file.
When you export a video, any changes you’ve made to the Start, Trim-In, or Trim-Out times
determine how long your new exported video is compared to the original video that you inserted into
your SONAR project.
To export a video
1. Make sure your audio tracks are completely mixed, and your video Start time, Trim-In time, and
Trim-Out time are set the way you want them.
2. Use the File > Export Video command.
The Export Video dialog appears.
3. In the File Name field, type a name for your new video.
4. In the Files of Type field, choose the kind of video file you want the exported file to be.
5. Click the Encoding Options button to open a dialog of encoding options for the kind of file you’re
creating. Some codecs do not work: click the Help button in the dialog for help choosing options.
6. Click the Audio Mixdown Options button to open a dialog of audio mixdown options. Click the
Help button in the dialog for help choosing options.
7. Click Save to export your video.
Optimizing video performance
Here are a few tips to optimize video performance:
• Viewing your video in on an external DV device will significantly decrease the processor load on
your computer if the video stream is a DV AVI file. See “Video playback on a FireWire DV device”
on page 228 for more information.
Note: If you’re exporting an AVI file, the No Compression option in the Video Codec field of
the AVI Encoder Options dialog is a good choice. This choice does not change or compress
your source video material. If you want your exported AVI file to be compressed, the Cinepak
option will create an AVI file that plays back smoothly with decent quality. The MJPEG option
will create an AVI file that does not play back as smoothly, but is a high quality format to archive
a file in.
Note: If you’re exporting an AVI file to either a 24-bit audio format or to a multi-channel
(surround sound) format, set the Audio Codec in the AVI Encoding Options dialog to No
Compression.
