Or is 1080i simply better looking than 720p for content that isn't fast moving. |
don't for sure.
Also, most cannot see the difference between 1080p and 720p when
viewing from three times the height of the monitor, or at least from
what that I have read and experienced.
One can only compare the encoding of two different formats when
comparing like encoders with like algorithms. A 480i picture could
look better than a 1080p depending on source and encoding.
Cheers...

crap group, should've posted somewhere else. |
information and seem to expect instant gratification,
are unwilling to learn how to use the tools mentioned,
or do the simplest search for topics that have been
discussed over and over again. There are people
here who could help answer any specific questions
regarding the topics you raise, but who wants to
spend a great deal of time going over the basics,
that you can get from a simple Google search.
Read up a little, knock that chip off shoulder,
come back and provide useful data that relates to
your questions, be responsive to requests for
more information; and you will likely learn a lot.

Depends on how much of a videophile you are. If you have a keen eye I
think 1080i is supposed to look better than 720p, but 720p displays
fast moving images better like sports and action movies. That's why
espn uses 720p but the networks use 1080i.
As for 1080p, you have to get closer to the screen to see the better
quality. I haven't looked at 1080p yet. People who aren't too
discriminating probably won't notice too much of a difference but if
you're a videophile you probably will.

is it because 480 is good but not *great* and 720 is just about as
detailed as one would need in a regulat setting like 10 feet from a42
inch tv?
can anyone clear this up for me?

Because 720p is almost like 1080i. 720p's lines are progressive and
1080i's lines are interlaced. The eye doesn't differentiate too much
between progressive and interlaced so their "almost" equal. Unless you
are a discriminating viewer. 480i however is a far cry from either of
them.

I imagine that would be like comparing 720p to 1080p. 1080p is much
better if you're a discriminating viewer. It's like mp3's. Lot's of
people just listen to 128kb mp3's that can even be badly encoded mp3's
and it's good enough for them and they never notice any degradation of
quality, but for people who really notice quality, they will notice a
big difference between a bad 128kb mp3 and a 320kb mp3 which has the
sound of a pristine cd. This is audiophile territory. Now if you're a
videophile you will definitely notice the superior quality of 1080p.
So to answer your question, 480p probably sucks compared to 720p
