220 VIDEO CAPTURE
Direct WMV capturing
Video Capture allows you to capture video from any type of video source straight
to Windows Media Video (WMV) format. WMV is an extensible file format that
handles synchronized multimedia data and supports "live content" transmission
over a wide array of networks.
To directly capture to WMV format:
1. Connect your camcorder to the computer. (See
details). Turn the device on and set it to VCR or VTR mode.
When acquiring video from an analog source, be sure that the analog
capture card you are using supports RGB or YUV capture.
2. In Video Capture, select Setup: Change Capture Plug-in.
3. In Current capture plug-in, select Windows Media Format Capture Plug-
in.
4. Select Setup: Video and Audio Capture Property Settings (or click
Properties in the Advanced tab of the Capture Video dialog box) to choose a
profile that contains capture settings for WMV. See
page 220
for details.
5. To capture video, follow the steps in
page
213.
Selecting a profile
The quality of a WMV file depends on the profile it is using. A Profile covers
various attributes for a Windows Media Format file such as bit rate, number and
type of streams, compression quality, frame size and so on. When capturing video
directly to WMV format, Video Capture uses the default profile to complete the
capturing process. You also have the option to select other profiles to attain
preferred captured file quality.
To select a profile:
1. Select Setup: Video and Audio Capture Property Settings (or click
Properties in the Advanced tab of the Capture Video dialog box).
2. In the dialog box, click Select to open Select Profile.
3. Select the profile you want to use for capturing. The generated WMV file will
depend on the profile that you pick. Click OK.
