Chroma sampling for fast-motion video Select this option to help
eliminate artifacts such as jagged edges and unwanted lines at the edges of
fast-motion video (for PAL video only).
¡ Important When rendering graphics and titles, make sure that Chroma
sampling for fast-motion video is not selected, as this option can cause
jagged edges to appear in your rendered images.
6 Click OK to save your settings. Any change you make to your selected
luminance range setting (such as switching from Standard to Expanded )
will only take effect the next time you start your VFW program.
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.
