Setting the video image size
The maximum suggested video image capture size is 320x240. When playing
back the video on slower PC’s, a smaller image size might be needed. To set
the image size, click on
FMT Button:
The WinTV-Capture program can use several different types of color formats
when capturing video clips. For highest capture performance, choose the YUY2
OR RGB formats. These give excellent capture image quality and frame rate,
but will give slow performance on playback of 320x240 image size videos.
YUY2 OR RGB formats are also good if you plan to edit your video clips with
Adobe Premiere or MediaStudio, and plan to compress the digital videos using
Cinepak or Indeo. If you do not plan to edit your videos and want good play-
back performance, choose a smaller image size (160x120). Capture and play-
back performance is determined by your system configuration, including CPU
and hard disk speed.
Setting the number of frames per second captured
To set the number of frames per second captured, click on File/CaptureSetup :
The number of video buffers will depend upon how much RAM you have in your
system. The maximum number of buffers is 1000.
After setting the video format, the number of frames per second and possibly
creating a new file name (by clicking on
File/SetCaptureFile ), you can start cap-
turing video by clicking on the Capture Video icon.
