What is Matrox M.Key/100?
Matrox M.Key/100 is a USB dongle with associated software that allows you to
use all the Matrox Video for Windows (VFW) software codecs on a system that
doesn’t have Matrox video hardware. With Matrox M.Key/100 connected to your
computer’s USB port, all the Matrox VFW codecs are available on your system
and behave as though you have Matrox video hardware, such as Matrox Axio or
Matrox DSX, installed in your computer.
This means that you can render and play back Matrox .avi files with your VFW
programs using any Matrox VFW codec, including those codecs that are
available only to users that have Matrox video hardware. The following Matrox
VFW codecs are available with Matrox M.Key/100:
• Matrox DV/DVCAM.
• Matrox DVCPRO.
• Matrox DVCPRO5O.
• Matrox DVCPRO HD

.
• Matrox MPEG-2 I-frame in SD or HD resolution

.
• Matrox MPEG-2 I-frame + Alpha in SD or HD resolution 1 .
• Matrox Uncompressed in SD or HD resolution.
• Matrox Uncompressed + Alpha in SD or HD resolution.
• Matrox Offline HD.
• Matrox M-JPEG (for legacy DigiSuite files).
• Matrox HDV (for playback only of Matrox HDV files)

.
Because the Matrox VFW codecs will behave as though you have Matrox video
hardware, Matrox offline HD files will be upscaled to full-screen size for
playback with your VFW program, and you’ll have full support of the Matrox
MPEG-2 I-frame HD codec to create .avi files with or without alpha in all
supported HD formats, including 720p, HDV 1080i (1440 × 1080), and full-size
1080i (1920 × 1080). For details on using the Matrox VFW codecs, see “Using
Matrox M.Key/100 with VFW programs” on page 5.
¡ Important If M.Key/100 is not connected to your computer’s USB port when
you render or play back Matrox clips, any clips that use a video compression
format that requires the Matrox video hardware, such as MPEG-2 I-frame HD +
Alpha, will display as invalid video.
1 The Matrox DVCPRO HD, MPEG-2 I-frame + Alpha, and HDV VFW codecs require Matrox
video hardware and are available with M.Key/100. Unless you have Matrox video hardware
or M.Key/100, the Matrox MPEG-2 I-frame HD codec supports HDV 1080i (1440 × 1080)
files only.
