Matrox Utilities icon.

3 Under Input Source, select the Video and Audio inputs that you want to
capture.
Remarks
$ The SDI embedded audio option can be used with the SDI video input
option only.
$ When capturing from an HDMI source, only uncompressed embedded
audio is supported.
4 To capture an unstable or low-quality video signal, such as from a
low-quality composite or S-Video VCR, select
Capture unstable video
signals
to ensure that the capture application does not stop the capture due
to a poor video signal/signal loss. The captured video, however, may include
dropped or black frames. If this option is disabled, a low-quality video signal
or signal loss may cause the capture application to stop the capture.
5 If the format to which you want to capture does not match the format of your
source video, select

downscale, or cross-convert to the desired capture format. For example,
select
Scale input for capture if your source video is 720p at 59.94 fps and
