Re: Fuzzy Still Pictures



I don't think that's quite what he said, but you are entitled to your
misconceived interpretation. Just don't spread it around.



Some people just insist on being wrong, and there's nothing I can do about
it, but challenge them. So tell us how it is that image resizing and/or
changing pixel aspect ratio is different for "DV-AVI (NTSC)" and "High
Quality Video (NTSC)". They are both 720x480 are they not? Therefore does
the image not have to be resized the same for both? And just for the sake
of argument, assuming a change of pixel aspect ratio, would this not be done
for both formats too since they are both 720x480?



I am not, and never have questioned that down-resizing the pixel count of an
image will not have an impact on it's quality. That is a given regardless
of tool used. But it has to do that regardless of saving as "DV-AVI (NTSC)
vs. "High Quality Video (NTSC) as they are both 720x480.



Based on my limited understanding of digitized images, it does not seem that
changing pixel aspect ratio will change the quality of an image. Just it's
H/V proportionality.



I will admit I am not a video/image expert and my positions, premises, and
reasoning at times may not be totally complete and 100% accurate, and
perhaps sometimes just plan ol' flawed. But what you are trying to put
forth just does not make technical sense to me. Furthermore you still have
not shown any evidence of DV-AVI non-square pixel specification. If you can
adequately build your case to prove, then I will subscribe, but so far you
have not been able to do that. Who knows I could still wind up with egg on
face, but so far it doesn't look that way.
