Thanks for this interesting post - I was the
one you mentioned above who saw a friend's MOST
impressive HDTV front projection system (that looked
nothing short of truly amazing on HDTV material, and
MUCH better than anything I had seen in stores),
with very good display of wide-screen DVDs, soft
but acceptable display of SD broadcast material,
and HORRIBLE display of my SD-D25 Mini-DV material
(with "S"-cable direct-connection into the front
projector). What was amazing to me was that the
above was true, yet ALL of the better-looking
material had lower data-rates, and all but the
HDTV had lower resolution. I also have seen my
Mini-DV material displayed large on SD gear with
it looking good (and I'm well aware of the range
of "nasties" D25 is capable of showing - see:
www.David-Ruether-Photography.com/vid_pict_characts.htm).
I was willing to call this a conversion problem
with this particular projector (or with
resolution-halving projectors in general...),
but your post (and John Dyson's, above) made me
wonder again about this issue...
Sigh...
More on this?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I can clearly state (demonstrating with my own video
equipment), that DV50
type formats (50mbps versions of DV) look alot better on
HDTV than DV25. It
is possible to partially clean-up the DV25 picture, but the
damage done by
the compression scheme is impossible to totally remove.
Even with OTA NTSC, if you look carefully, and have a fairly
clean signal,
you can see the DV25 artifacts pass through. BetaSP tends to have a soft
look also, but it is much easier to see the effects of
BetaSP on SDTV
signals.
DV25 is still a really nice format for home use.
