> Select Format, and then click the desired .avi output video
format, such as
1440x1080i @ 29.97 fps.

identified with an asterisk (*) in the list. If you create an .avi file using an
unsupported format, it will not play back in real time on your Matrox RT.X2

¦NoteOnce set, the output format and configuration settings apply to all
subsequent .tga sequences that you convert to .avi files. However, if you select
a 1440×1080i/p output format, the compressor for the .tga to .avi conversion
will automatically be set to
Matrox MPEG-2 I-frame HD + Alpha.

.avi file.
