have abrupt changes between different colors, such as a blue box on a
black or white background. You should select these options for most
animation and compositing work (computer-generated material). For most
video editing programs, however, it’s best that you

Rendering material to a Matrox VFW .avi file
When you render material to an
.avi
file, such as when you render a finished
composition 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.
If you want to export material from Adobe Premiere Pro to a Matrox
.avi
file, it’s
recommended that you use the Matrox AVI export format as explained in
“Exporting to a Matrox .avi file”
