and thus improves capture performance. (In most cases, use the default unless you
have a reason not to.)
• Number of video buffers (1-1000) sets aside additional buffer memory to help
improve captures. (In most cases, use the default unless you know how much buffer
space you can afford.)
• Properties allows you to customize settings that are specific to the video source
format or to the target capture format. For instance, clicking this button opens the
DV Type dialog box when you have set up the program for DV capture, or opens the
Video and Audio Capture Property Settings dialog box when your video source is
analog video or TV footage.
• Default lets Video Capture automatically determine the best settings for your
system. Click this when you do not know what options to specify or are unsure about
your system's setup.
Capturing video from a DV camcorder
To capture Digital Video (DV) in its native format, make sure you use the Ulead
DirectShow Capture Plug-in . This saves the captured video as a DV AVI file
(.AVI).
Also, select Setup: DV Type (or click Properties in the Advanced tab of the
Capture Video dialog box), then choose whether to capture DV as DV type-1 or
DV type-2 . With DV Type-1 , the video and audio channels are stored unmodified
as a single, interleaved stream in the AVI file. With DV Type-2 (which is the
default), the video and audio channels are stored as two separate streams in the
AVI file.
The advantage of Type-1 is that the DV data does not need to be processed, and is
stored in its exact original format. The advantage of Type-2 is that it is compatible
with video software that is not specially written to recognize and process Type-1
files.
Follow the instructions in “To capture a video sequence:” on page 213 to capture
video. In addition, when Auto (no time limit) is chosen as the Capture method
in the Options tab of the Capture Video dialog box, select Seamless capture to
automatically save the captured video as another video file once it reached a size
of 4GB. Use seamless capture if your hard drive was formatted using the FAT32 file
system. For information on setting up seamless capture,
see “Seamless DV and
MPEG capture” on page 219 .
