Topic: Aspect Ratio Question

[ABCmotorparts]

Sirs,

Pardon the newbie question,

I am using a 42pv70, set to 16.9, as well as a Pioneer DV400 upscaler, also set to 16.9.

Now, we (me and surg) noticed while watching the movies Saving Private Ryan (R1 with an aspect ratio of 1.85:1 anamorphic widescreen), and the Jurassic Park Trilogy (R1 also with the same aspect ratio of 1.85:1 anamorphic widescreen) bakit nag-full screen sila sa display, now when we set the upscaler to 4.3, saka pa lang siya mag-widescreen sa display?

I tried to do some research about aspect ratios via the net but ended up confusing myself more...

Thanks..!

Benedict

What do you mean by full screen?

Is it like this?



or



The picture below is what you are supposed to see on your widescreen tv if your DVD is 1.85:1 Anamorphic format..

Hi oreoshake..

its like the 2nd picture, without the black bars...

This is what you see in your widescreen tv if your DVD is 2.35:1 Anamorphic format:

Yes walang black bars up and down if 1.85:1 ang format.. sa 2.35:1 meron black bars.. both yata walang napuputol na image except that sa 1.85:1 na stretch vertically ang image..

[ABCmotorparts]

Ahhhhh... I see,..

Thank you,...

[ABCmotorparts]

I'll try to post some screen caps of both settings later.
Parang may cropped image sa itaas and ibaba eh.

Anyhow, thank you for all the replies, keep 'em coming,

Cheers,

Hindi ko masyado na gets ang description e.  Let's agree on the terminology first.

It used to be that the terms were just full screen and widescreen/letterbox, when very few had widescreen TVs.  Now that widescreen TVs are more common, the terms have become confusing.  Today, when you say "fullscreen", it can mean either a 4x3 picture or a widescreen picture, depending on whether you're viewing it on a conventional TV or a widescreen TV.

The new terms commonly used for widescreen TVs are: 


Letterbox:




Pillarbox:




Windowbox:




As for 1.85:1 images, remember that a 1.85 aspect ratio is not exactly equivalent to a widescreen TV's aspect ratio.  A widescreen TV is 16 x 9 or 1.78:1 (16 divided by 9).  Notice that a 1.85 source is wider than a 1.78 TV, which should still give you black bars (letterbox).  If the 1.85 source is shown on a 1.78 TV without black bars, that's because the TV is overscanning the image.

I hope my old posts help:

You might be under the impression that a "widescreen" picture has only one type of aspect ratio, namely 16x9, when there are actually more than ten different widescreen aspect ratios, the most common of which are: 1.78, 1.85 and 2.35.   

Since your TV is 16x9 or 1.78:1 (16 divided by 9), any video source with a picture wider than 1.78 should give you a letterboxed image.  The wider the aspect ratio, the taller the black bars. 

However, 1.85:1 aspect ratios will require further explanation:

Almost all widescreen TVs overscan a 1.85 image to completely fill a 16x9 screen.  Thus, as a result of the overscanning feature, you should have letterboxing only on pictures wider than 1.85.  But the exception is for HDMI inputs, where overscan is usually (but not always) eliminated by manufacturers.  Without overscanning, you will still see very slim black bars (sometimes only one very slim black bar) for 1.85 content on most widescreen TVs via HDMI connection.

There are many, many movies with a 2.35:1 aspect ratio, so it would be easy to find examples.

For aspect ratios wider than 2.35:1, the most common is 2.40:1 (actually 2.39:1, but commonly rounded off to 2.40:1).  Examples -- Minority Report, The Island, Terminator 3.

The widest aspect ratio I've ever seen on video is 2.76:1 on Ben Hur (Charlton Heston, 1959), shot on MGM Camera 65 (a.k.a Ultra Panavision 70), using 65mm film with 1.25x anamorphic.


2.76:1 image from Ben Hur

The widest aspect ratio I've ever heard of is 4:1, shot on Polyvision using three 35 mm films projected side-by-side.  It was only used once -- on the ending of Napoléon (French silent movie, 1927).   

Update:  Ben Hur is no longer the widest on home video:

It's a misprint all right ---- a misprint by Amazon!     

The correct spec is 2.89:1, and yes, this aspect ratio is now the widest in home video, exceeding Ben Hur's previous record of 2.76:1.

In his DVD review, Colin Jacobson writes:

When I looked at the DVD specs for 1962’s How the West Was Won, I thought the case came with a misprint. It listed the film’s aspect ratio at 2.89:1. To date, I believe that Ben-Hur was the widest flick I’d ever seen on DVD, and that one stopped at 2.76:1. Won went beyond that for its super-wide presentation.

How the West Was Won was shown in the Cinerama theater with an aspect ratio not greater than 2.59:1.  That's because the maximum practical aspect ratio for Cinerama is 2.59:1.

This movie was originally released on DVD at an aspect ratio of about 2.40:1.  The new release now has an aspect ratio of 2.89:1 on DVD and Blu-ray, plus a first-ever "Smilebox Format" for the Blu-ray version.


The original Cinerama negatives are wider than the image produced on the actual release prints.  Warner scanned the maximum image from the negatives so they can have more allowance for working on the 3-panel joins.  Since the scan produced a picture wider than the original release prints, it was possible to produce a home video with an aspect ratio wider than the actual presentation in the Cinerama theater.

Screencap comparison from avsforum:  Old DVD vs. Blu-ray letterbox vs. Blu-ray smilebox: http://www.avsforum.com/avs-vb/showthread.php?t=1067722

Notice the left and right edges of the pictures.  The 2.89:1 image adds much more to the old DVD frame.  Notice also that the smilebox version has some slight croppping.

Sir Barrister,

Thank you for posting your reply,
I was really going to send a PM to you about this inquiry,
anyhow thank you for your answer.

And for all other newbies on board, I found this link that somehow explained it further:

From what I know 1.78:1 ang walang black bars if your screen is 16:9, this is because 16:9 = 1.7777777777777778.

Pag 1.85:1 meron pa rin small black bars.

Pag 1.85:1 meron pa rin small black bars.

Yun nga din ang ini-expect ko, pero after testing 4 DVDs with the same aspect ratio of 1.85:1, it filled up the whole screen... In order for us to see the UNCROPPED movie, we had to set the DVD player to 4.3, then the black bars would appear.
