Video playback, import, and export
Controlling Playback
hold down the CTRL key, then the frame increment value is used (default = 5 frames). You can also
use the [ and ] keys to seek by the frame increment.
If your video does not play back in sync with your audio, see Synchronizing external video playback
to audio.
External DV output (IEEE 1394/FireWire)
SONAR relies on the Microsoft AV/C drivers to communicate with DV devices that are connected to
a IEEE 1394 FireWire bus on your computer, in order to control and preview video to digital video
devices.
If another software application overwrites or disables these drivers, the Preview to FireWire and
Print to Tape feature may not function correctly. If you are going to install a software application that
uses DV devices connected to the IEEE 1394 FireWire bus, please check with the software vendor
about DV device drivers it may install. Also, please check with the manufacturer of your DV device
for AV/C-compliance information. The following devices have been tested and known to work
properly with SONAR:
• ADS Pyro A/V Link DV transcoder
• Canopus ADVC-100 DV transcoder
• Canon ZR-85 miniDV camcorder
Exporting a project to a FireWire DV device
Once your project sounds the way you want it to, you can export the video and audio together to an
external FireWire DV device. This is called “printing to tape,” if your external device uses tape.
To export a project to an external DV device
1. Use the File > Export > Video command to open the Export Video dialog.
2. In the Save as Type field, choose AVC Compliant Device. You might see a different name in the
drop-down menu, depending on what type of external device you are using.
3. Click the Audio Mixdown Options button to open the Audio Mixdown Options dialog.
4. In the Audio Mixdown Options dialog, choose the following options, and then click OK:
• Channel Format. Choose Stereo.
• Sample Rate. Choose 48000.
• Bit Depth. Choose 16.
5. In the Export Video dialog, click the Encoding Options button to open the property page of your
external device.
Note: When using DV AVI movies, the transcoding unit must be set to the same format (NTSC
or PAL) as the video file, or Preview to FireWire and Print to Tape will fail to work properly. Also,
CPU consumption will be lower when the source material is in DV format, since the format is
native to the FireWire device and doesn't incur a CPU hit for transcoding video.
