Jim,
Not quite. All NTSC encoded video is essentially 320 x 240 and VHS
with its AM "color under" system makes it even worse because of color
artifacts in the luminance. 640 x 480 which is a SMPTE and ITU
standard is only possible with RGB component systems where no
NTSC encoding has taken place. Because of the "non locked "color
under" system of VHS no improvement of significance is possible in
any digitizing or upconverting system. In fact digitizing noisy
video usually makes the noise noticeably worse because of bit
uncertainly in the least significant bits.

Larry,
Maybe your tape has is a better reproduction than the one I have of the
SPAM video. VHS as I recall is 640 X 480 whereas what I posted was 320 X 240
resolution. If you got a decent copy, maybe somebody can convert that to a
VCD or DVD for those that want better quality video?
Anybody think about making a AM new video in 2006?
Regards,
Jim

I still have my VHS copy from 20 years ago, too. I most recently watched it
with a friend (W1UJR) a couple of years ago.
