information; the larger the bit value, the more colors can be
used, but the larger the file size.

adjust the video image size
(resolution) settings for the currently
selected format. The data rate

take audio into
account.
Note:
Your Matrox product doesn’t support hardware-accelerated MJPEG encoding and
decoding. Because of this, certain Matrox software controls are unavailable.
Overlay and preview modes
The video capture program you’re using may give you a choice of
overlay
or
preview
modes.
Overlay and preview settings affect how video is viewed or captured:
!
With overlay mode, everything
on
the video window is captured. For example, any part
of a dialog box overlapping the video window appears in the captured video.
!
With preview mode, you may get a lower frame rate (possibly resulting in jerky video)
and you may not be able to view or capture video if there isn’t enough graphics
memory available. The amount of graphics memory available depends on how much
memory is on your graphics card, the size of the video window, and the resolution and
color palette settings of your display.
