Playing QuickTime DV Video Through the FireWire Port
(Mac Only)
To Play QuickTime DV video through the FireWire Port:
1 Import a QuickTime video file into a Pro Tools session. (See Importing Video into Pro Tools for detailed information.)
2 Choose Options > Video Out Firewire.
When this option is enabled, Pro Tools will play the video (NTSC or PAL) out the FireWire port to an external DV decoder.
If the Video window is open while video plays out the FireWire port, it displays text indicating that video is playing out the FireWire port.
