Matrox Marvel G200
Giga-Byte GA6-BXE
PII-400; 128M RAM; mucho disk space
Windows 98 for capture
NTSC video (USA)
My ultimate goal is capturing to AVI then encoding to
MPEG-1 for NTSC VCD playable in tabletop DVD players.
I capture at 352x480 to MJPEG with minimum compression,
then encode to MPEG with various encoders (Xing,
Panasonic, Ligos).
One of the messages here or in the Matrox docs said
that it is best to capture at 352x480 if MPEG-1 output
is the goal.
Question is about this 352x480 capture, and how it
gets squooshed to 352x240 for TV viewing. What phase
of the encoding is supposed to do this, is this what
is meant by "deinterlacing"?
This seems to happen by magic in Xing and Panasonic
encoders, but not in Ligos. I choose "Deinterlace"
in Ligos' Advanced options, and the video looks OK
while it is encoding, but when I view the result in
Media Player, it's double height. Xing and Panasonic
seem to take care of this. I'd like to use Ligos
if possible because it gives the option of "one
header per GOP" which is supposed to make a VCD
play better in a tabletop DVD player, enabling
FF and rewind.
I've also seen inconsistent behavior when viewing
the MJPEG .avi as it comes out of PC-VCR. Sometimes
Media Player will show this double height as well.
Someone who knows about this, please 'splain me!
Thanks.
