I found one more 'aspect ratio' designed specifically for allowing
Cinerama and the other roadshow films to be transferred to DVD and
viewed in their original 2.55:1 through 2.89:1 aspect ratios and also
be seen as if being projected onto the huge, deeply curved screens as seen in a Cinerama theater.

I remember saying that there would be many display sizes and aspect
ratios, which is exactly what has happened.

Exactly what happened? Keep dreaming.

Here's what happened:

Movies are either 2.35:1 or 1.85:1 for all theaters.

No Bert, some are 2.25:1, 2.66:1 and a few are 2.75:1. There are at
least *eleven* different aspect ratios in use for major films and many
more have been used for minor ones.

And a lot are 1.37:1 But, that's another story. See the following link:
http://www.widescreenmuseum.com/widescreen/intro.htm

Those that go to IMAX theaters are square, but only when they are
projected in IMAX. If a movie is sent to IMAX and regular theaters,
you never see the square format used in regular theaters.

Again No, there are at least two major IMAX aspect ratios and probably
others.

TV screens are 16:9. Even the 4:3 ratio initially used in small LCD
TVs, e.g. in the original LCD TVs of 20" or less, has disappeared
years ago.

Computer screens are typically 16:10, unless the computer is used as a
media center, in which case 16:9 is an option.

What about all the 14:10 TVs and PC monitors?


Not much variation there, Craig. Even portable devices are going to
wide screen formats. If they don't go to 16:9 or 16:10, it is only
because of the constraints placed on them by their tiny size. And no
one particularly cares on tiny screens anyway.

Bert, most of this is wrong. For a good sense of all the bad
letterboxing work that has been foisted by the makers of DVDs on classic
films see the following three links from the
"American Widescreen Museum website:
http://www.widescreenmuseum.com/widescreen/lbx.htm

Are you telling me that there's some artistic "intent" for syndicated
shows, in SD, being transmitted as 4:3, when the original transmission
in HD was 16:9?

If the original was 16:9 then it is most likely a station that is
requesting and broadcasting a 4:3 version. As you point out, the ability
to support widescreen is available to everyone. Ask the folks you are
talking about why they are dragging their heels?

That's why I wrote that question down, Craig. There is no so-called
"artistic intent" in most of these mismanaged aspect ratios.

The HELL you say. Go through the American Widescreen Museum website. All
of it. Then rethink your postings.

Cliff

There's simply no excuse for multicasts such as ThisTV to be
transmitting movies as 4:3, unless the movie is truly ancient. Just
about any movie produced after the 1950s would best be sent anamorphic
16:9, and even many movies of the 1950s. Ditto goes for newer TV shows
in syndication.

I would have much preferred if 16:9 had become the standard display
ratio after the transition to DTV, so these so-called "artitistic
intent" compromises would have been over with by now.

And also, as much as people don't want to see black bars in TV
screens, they will also object to black bars in their computer
screens, when streaming media full frame becomes a more common way of
viewing TV. It's one thing to talk about multiple aspect ratio windows
open, in typical PC work, quite another to concentrate on the full
frame streaming media experience. The latter is no different from TV.
