Remarks
If you selected DV-1394 as your input device, the name of the DV-1394
$
device connected to your system will appear in the Input Source box.
If Matrox Axio can't detect your source device when you start a capture,
$
you'll receive an error message. Either black video will be captured or the
capture won't be able to start until a valid input signal is present. In either
case, you must make sure that your source device is switched on and
properly connected to your system to properly capture the video.
To capture analog or SDI input for a 486p @ 23.98 fps sequence, you
$
must specify In and Out points for your captured clips (manual captures
are not supported).
From the Input Format list, select the video format that matches your
6
source video. Depending on your sequence's 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
sequence's video format. For example, if your sequence's 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
7
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
video for an HD sequence, the Input Aspect Ratio will be set to 16:9 .
8
Under Capture Format , select your desired capture format from the list. If
you're capturing DVCPRO HD material to an .avi file from a DV-1394
device, the video will be captured natively over the DV-1394 interface and
the Capture Format will be set to Native DVCPRO HD . If you're
capturing to an .m2v file, the Capture Format will be set to Matrox
MPEG-2 IBP
.
¦ Note
The formats to which you can capture clips depend on your sequence's
video format and Matrox Axio hardware. For more information, see
"Supported video compression formats"
