Option: Convert from 4:3 to 16:9 - actual format is...?

[TECK]

For option: Convert from 4:3 to 16:9 - actual format is 2.35, 1.85 or...?
Thanks guys.

EDIT: I'm going to test it now and post results. :)

Something is really wierd. I can't see properly the ripped file in Fit2disc???
It looks like the movie is streched behind the application's viewable area...

While played in a regular dvd player, it shows as anamorphic. I'm going to burn it, I will see if it's not 2.35, at least.

Rebuilder's "convert from LB 4:3 to 16:9" crops the black bars off the top and bottom, assuming they are actually encoded in the picture, and flags the stream's aspect ratio to 16:9. It doesn't convert to letterbox; it removes the letterboxing to claim the wasted bit space and resolution for the actual picture. Only do this if the source stream says 4:3, but the picture is definitely widescreen.

Thanks for the info. DVD-RB cuts the top and the bottom, while resizing...
Take a look.

What's the actual format? 2.35? Thanks.

Look how it looks the second screenshot in Fit2disc:

You don't see anymore the black bars...

[mrslacker]

I don't understand what those images are. Could you label them?

Movies can be in any weird aspect ratio. The DVD standard provides for mpeg at 16:9 and 4:3. If it's any thing else, there are black bars encoded into it to get it that way. This is extremely common and how they get 2.35. Check out all these movies (http://www.imdb.com/Sections/DVDs/AspectRatios/) . According to Imdb, there are a few dozen ratios... a few dozen variations of black bars on a D1 frame/DAR flag combo.

Bottom line, I have no idea what your source is. But the exact ratio of the picture with video is probably irrelavant.

Hey TECK!

I understand what you ask for, and from my best knowledge, the picture you are geetting after the conversion/cropping is in fact something close (or perfect match) to a 1:1.85.

On another note, mrslacker is also correct.

[Edit:] But, given the pictures you've post here, the aspect ratio to the naked eye is a 1:1.85 and not the 1:2.35, though all of the StarWars movies were filmed with an original aspect of 1:2.35 as far as I know.

of course your pictures are cropped

dvdrb just chops off the top and bottom of the pic to go from 4:3 to 16:9. It assumes the source is letterboxed. Your 4:3 movie is fullframe. IT is not intended for this

[jdobbs]

There are only two aspect ratios in use on a DVD. All DVDs are either 4:3 or 16:9. A 2.35:1 aspect ratio source will have borders put on the top and bottom to make it fit into one of those.

The 4:3 -> 16:9 conversion was designed to take originals that put a widescreen production into 4:3 format and convert them to 16:9 so they wouldn't become a ridiculous looking picture that has huge borders around it on a widescreen (16:9) television.

When you convert it, the black bars are taken from the top and bottom and the picture is stretched vertically -- that's because it is now anamorphic.

One thing to remember is that you should never use this option to convert 16:9 widescreen back into 16:9 widescreen. It will cause image distortion. If you want to take a 16:9 widescreen original that has an encapsulated 2.35:1 displayed, and you want to zoom in -- use the AVISYNTH LanzosResize() filter to do so -- and keep the pixel aspect ratio the same.

That's what I was saying four posts up. "The DVD standard provides for mpeg at 16:9 and 4:3. If it's any thing else, there are black bars encoded into it to get it that way." But it's nice that you back me up. :)

@TECK
You know how to do this! It was your thread (http://forum.doom9.org/showthread.php?t=93370). ;)

[TECK]

Yep, I do know this mrslacker! :D I use the Lanzos4Resize() filter on a regular bassis, for all my 2.35 movies.
I was questioning the 4:3 to 16:9 process. Thanks guys for the good info posted.

So, I should use this for something like Vertigo? It's a 1.85:1 film, but non-anamorphic on the original R1 pressing.

Even though I don't have a widescreen tv, I do have 16:9 squeeze mode, so it should be an improvement, correct?

[jdobbs]

Not sure if "improvement" is the right word, you can never actually make a copy better than the original except what you might clean up with filtering... but it does definitely make the film a lot more enjoyable on a widescreen TV.

I hate widescreen presentations that have been squeezed into a 4:3 format... the DVD authors who do that should be gathered up an stoned. There are quite a few DVDs of classic films done this way... sigh.
