5 From the Input Format list, select the video format that matches your
source video. Depending on your editing video format, you may not be able
to change the input format. If needed, Matrox Axio will apply an appropriate
pulldown method to convert the incoming video to your editing video
format. For example, if your editing video format is 1080p @ 23.98 fps and
you set the Input Format to 1080i@29.97fps , a standard reverse pulldown
(2:3 cadence) will be applied to capture the video to 1080p @ 23.98 fps.
From the Input Aspect Ratio list, select the aspect ratio of your SD source

video (4:3 or 16:9). For example, to capture video that was recorded using
the standard TV screen format, select 4:3 . To capture video that was
recorded using the widescreen 16:9 format, select 16:9 . If you're capturing
HD video, the Input Aspect Ratio will be set to 16:9 .
Under Capture Format , select your desired capture format from the list.
