Chapter 5, Using Matrox RT.X2 with Video for Windows Programs
Rendering material to a Matrox VFW .avi file
When you render material to an .avi file, such as when you render a finished
video production or an animation, you must select the compressor (codec) you
want to create the file. The compressor determines the quality of your rendered
video. Refer to your program’s documentation for instructions on how to select a
compressor for your .avi file.
¦ Note When specifying your Export Movie settings in Adobe Premiere Pro,
you must set the File Type to Microsoft AVI on the General page, then select
the compressor you want on the Video page.
° To create a Matrox VFW .avi file:
1 Select one of the following codecs from your program’s list of available
compressors:
$ Matrox DV/DVCAM Renders video to DV or DVCAM format.
$ Matrox DVCPRO Renders video to DVCPRO format.
$ Matrox MPEG-2 I-frame Renders video to MPEG-2 intra-frame format
using the 4:2:2 Profile @ Main Level at a selected data rate (SD resolution
only).
$
Matrox MPEG-2 I-frame + Alpha Renders video to MPEG-2
intra-frame format with alpha using the 4:2:2 Profile @ Main Level at a
selected data rate (SD resolution only). This codec is available only on a
system that has the Matrox RT.X2 hardware.
$ Matrox MPEG-2 I-frame HD Renders video to MPEG-2 intra-frame
format using the 4:2:2 Profile @ High Level at a selected data rate.
$
Matrox MPEG-2 I-frame HD + Alpha Renders video to MPEG-2
intra-frame format with alpha using the 4:2:2 Profile @ High Level at a
selected data rate. This codec is available only on a system that has the
Matrox RT.X2 hardware.
¦ Note Additional Matrox codecs will be available, such as the Matrox
M-JPEG, DVCPRO HD, and uncompressed HD codecs. You can use these
codecs to create clips for use on other Matrox systems, such as Matrox
DigiSuite or Matrox Axio. For information about creating VFW clips for other
Matrox systems, see the documentation for those systems.
2 If you selected a Matrox MPEG-2 I-frame codec, click the Configure button
