2.40.1 ratio

[SG1-Viper]

hi there i see a lot of films are comming out in the 2.40.1 ratio can i assume that the picture will be even smaller in size than 2.35.1 i.e even bigger black bars top/bottom many thanks

"Smaller" is an odd word to use. Yes, the bars are bigger, but the actual height of the picture is the same, if you get my drift. It's like switching from an SDTV football game feed to the same game on HDTV. The wider screen doesn't chop anything off, it just adds more to the left and right ends.

He probabky means that the wider 2.40 picture would be just 800 x 1920 pixels instead of the 817 x 1920 pixels of a less wider 2.35 picture.

The problem, Mr. SG1-Viper is that movies haven't been made/projected in the 2.35 ratio since the start of the 70's when they went to a 2.40 (actually 2.39) wide ratio. And when soundtracks went digital (in 1993 I believe) the projector aperture got changed again to a very slightly smaller one, but still 2.39 (which would be 803 x 1920 pixels) so most Scope movies have been made/projected with a wider than 2.35 standard, they just keep calling it that. (btw before the 1957 standarization of the optical soundtrack, Scope movies were wider too: 2.55 wide)

So you see, of the almost 55 year history of Scope, 2.35 was the standard for only about 13 years (about a quarter of the time). And it has been 2.39 for more than 2/3rds of that time, to date.


Now, on the other hand cropping current 2K scans of a Super-35 Scope ratio movies to fit the 1920 pixel width of High Def almost gives you exactly a 2.35 image (and loses only 1% of the original 2.39 area) so on some cases you might get your cake and eat it too

Actually, I noticed the movie theaters in my area, both the digital theatres and the analog theatres use black bars at the top and bottom of the 2.35 movies.

While none are on the 1.85 movies.

Actually, movie theaters use both 2.40:1 (Constant Height) and 1.85:1 (Constant Width) screens, depending on the auditorium. Constant Height auditoriums use masking on the sides, and Constant Width auditoriums use masking on the top and bottom.

I must say I much more approve of Constant Height screens - here in the DC area the only specialty large screen that does this is Bow Tie Reston's BTX screen

My Cinemark theater uses Constant Height for all the regular auditoriums except the XD theater, which is the biggest screen. They use masking in the regular screens for movies in 1.85:1.

The picture area is smaller on an HDTV. The only way it would be the same size effectively, except wider, would be on a constant image height screen.

Jesus, the cobwebs on this thread...

[MisterXDTV]

The SMPTE standard for anamorphic scope has been 2.39:1 since October 1970 and it was confirmed in 1993, it gets rounded to 2.40:1 for convenience....

I've seen different transfers of the same movie listed at both 2.35:1 and 2.39:1 (2.4:1) and they look exactly the same. I for one, wouldn't be able to tell the difference.

and for those who have Projector, they have 16:9 panels, that when used with anamorphic lens, which are 4:3 expansion, you have ....
ta-da, 16/9 *4/3 = 2.37 aspect ratio....


now why did member "3Dfan" bring a 7 year thread back to life again

to give this on a scope CIH screen

Hence 3" border black velvet and over scan will handle any differences in exact aspect ratios


of course then you need side masking panels for sporting events, or the athletes look stretched fatty

Now, why is your home theater pictured in multiple threads? It's getting to be overkill now.

agreed, removed except the lens, and not sure how many have actually seen one

I wonder why that is - of the newer theaters I've been to - theater planners/architect have the screens tend to take up more of the entire wall: floor to ceiling, wall to wall thus when a 'scope film' is projected, the screen diminishes vertically.

Depends on if it's a digitally shot ratio or shot on film. Shot on film it also depends on if it's a Super 35 film or anamorphically shot. An anamorphically shot film's anamorphic ratio depends on how much of the film's negative space is used when unsqueezing the film to its' projected and shot ratio.

Early Cinemascope films used most of the negative on silent and not Academy size film, so it unsqueezed at 2.55:1 (2.549:1 in reality). Most films shot anamorphically use smaller modern academy size film though, but how much they want projected varies. 2.36:1 would be the ratio if they unsqueezed the entire negative image uncropped, but most crop the film a bit, and so you see 2.39 and 2.40 and 2.41 ratios.
Super 35 is basically a slightly wider full silent ratio film, but it's almost never projected that way, and it's usually used to fake widescreen. The film is shot with the .980 width usually in mind, and the height of the film is severely cropped to give it a widescreen look like anamorphic film, or 55mm or 70mm film. It's wider than normal Academy ratio 35mm film, but anamorphic film is shot 2x wider than Academy ratio but compressed/squeezed into Academy width so it's shot wider than Super 35 even if the film negative itself isn't wider. With Super 35 you can get a lot of varying aspect ratios more so due to there being no set standard ratio like anamorphic's 2.36:1, but they usually go for the 2.39 and 2.40:1 look of most anamorphic films. Just as an extra note, if Super 35 were shot anamorphically it'd have a 2.66:1 standard ratio.

Well, the XD screen does go wall to wall, and floor to ceiling. When they play a movie in scope, you can kind of make out the bars. But the regular screens aren't that big.

Showing off my HT pictures" and kept the relevant ones here?

I'm Trying to add value by explain aspect ratios and relevant picture.

And your post purpose is??
