Part 8: Capturing and Using DVThe advent of the DV (Digital Video) format has brought dramatic improvements in the ability to conveniently edit good-quality video on personal computers:
- DV is "real" video, high-quality, full-resolution, full-rate video and audio.
- DV is a digital format, so copies are exactly the same as the original, and no longer suffer the losses of converting back and forth to analog.
- DV is compressed in hardware in the camcorder, so there is no need for additional specialpurpose processing on a capture board.
- DV is compressed lightly, so it is reduced enough in size to be feasible to transfer and store on personal computers, but still high enough quality to edit and manipulate without damage.
- DV camcorders use the IEEE-1394 digital interface (also called FireWire by Apple and i1ink by Sony), so devices like camcorders can communicate with your computer using a single, consistent interface.
- The DV/1394 interface is two-way, so not only can you capture video from your camcorder to Premiere, but you can also export your clips and productions back out to the camcorder.
- DV and the 1394 interface also supports device control, so you can operate your DV camcorder directly from Premiere, and even schedule automated capture and recording.
- DV supports both audio and video, so both are captured together and stay in sync with each other.
- DV keeps a timecode with the recorded video, so you can organize clips on a tape with their exact timecode, and keep the timecode with the captured clips in Premiere.
©f Course, if you do not have a DV camcorder, Premiere also can capture audio and video clips using analog capture boards.
How to Connect Your, DV CamcorderThe first step in setting up your computer to work with your DV camcorder is to connect the two with an IEEE 1394 cable, and then configure Premiere to work with DV video. Premiere depends on the DV support in your operating system (Windows or Macintosh) to connect to and control your DV camcorder. It also depends on the IEEE 1394/FireWire hardware in your system to interface to your camcorder, which must be compliant with the OHCI specification.
1: Check Your DV Capture Board
If you have a DV-enabled Macintosh system, then DV support is built in. On Windows PCs, an add-in board typically provides the 1394 interface. To check your hardware, open the Start menu and choose Settings, Control Panel, and then open the System control panel. Click the Device Manager tab, and open the 1394 Bus Controller entry to check that your hardware is described as "OHCI Compliant."
2: Connect Your DV Camcorder
Connect your DV camcorder to your computer using an IEEE 1394 cable, as described in the documentation for your camcorder and 1394 interface. Plug the smaller 4pin connector on the 1394 cable into the DV interface on your DV camcorder (typically marked DV IN/OUT or IEEE 1394). Plug the larger 6-pin connector to the IEEE 1394 connector on your computer. Next, plug your camcorder into its power adapter, turn it on, and set it to VCR or VTR mode (tape player), not camera mode.
3: Select DV Preset
After the camcorder is connected and turned on, then launch Premiere. On the initial Load Project Settings dialog, select DV-NTSC (or DV-PAL), and choose the 32kHz or 48kHz audio preset, depending on the video and audio formats provided by your camcorder. Click the OK button...
