Adding a Matte to convert 16:9 to 2.35:1

[nobody2000]

How do I insert a matte so that I can resize a 16:9 video on DVD to a 2.35:1? I understand I have to rip the vob to an mpeg (in all likelihood) but what next? I tried using premiere, but when you render a 2 hour movie in premiere, you end up with a 2 hour uncompressed AVI file, and it's huge. What program can I use that gives me the capability to quickly resize and matte?

Also, what do i do in this program, if such a thing exists?

Why chop this perfectly functional material from the top and bottom of the picture?

What am I missing?

[nobody2000]

I didn't say chop...I mean I want to add to the top and bottom so I can squish the video down to a greater ratio. Right now, it looks stretched out.

16:9 is a standard DVD resolution and any DVD player will display it in correct AR.

[nobody2000]

Nooo..the film was shot in 2.35:1, and when it's displayed AS IS in 16:9, it appears stretched out....so, i need a matte so that when it sizes to the STANDARD 16:9, it doesn't look stretched out, b/c there is black matting in it's place.

[guns1inger]

Are you sure it is being played back in 16:9 ? It sounds like it is playing back 4:3, which is why it is stretched.

[nobody2000]

I'm positive..I've done LOTS of 16:9, 4:3 editing and encoding, for the most part I know what I'm doing...but I never ever needed to make a matte...is there a program where I can make a matte? Premiere does it, but it takes too long. Is there anything that'll draw a matte that WON'T take 3 days finish drawing the matte.

I don't care about 16:9, 4:3 or anything, my question is is there a program that does this, and where do i get it?

Why was the aspect ratio changed from 2.35:1 to 16:9 in the first place?

[guns1inger]

You don't need to matte it. You need to crop it to remove any black bars currently in place, resize it to meet 2.35:1 anamorphic size, then add borders to bring it up to spec.

Got Me...

When I open this in any editor, there are no black bars. That's the thing. It's a movie that was filmed in 2.35:1 AR and the kid who put this on the DVD didn't maintain this, as evidence when I take the ifo, and go in it to change the ratio to 16:9, the film is stretched (perfect circles are ovals...that's how I tell).

I want to resize. Seeing as no DVD player has a 2.35:1 AR setting (to my knowledge) I want to have it so that when you play it in 16:9, it APPEARS as if it were 2.35:1. This will require that either A.) I crop the video and lose perfectly good material or B.) I matte the top and bottom, so that when the video goes to fit a 16:9 AR, the black matting takes up enough space so the actual action going on fits a 2.35:1 ratio.

Everyone here is questioning my video knowledge, which is proficient enough to know what I'm talking about. My only question I really have is being circumvented.

My only question that I'm asking is is there a quick tool/program that'll let me do this? If not, I'll let it rest.

Thank you.

You could try demultiplexing the vobs to video and audio and trying Restream on the .m2v file and then reauthor to 16:9.

[guns1inger]

If there are no black bars then it is not 2.35:1 unless it is still stretched, even when viewed in 16:9 mode. If it is still stretched, then you need to resize it down in the vertical, add bars to fill it out, then re-encode as 16:9. If it is not stretched, then you can't get it back to the original 2.35:1, as the ends have been cropped.

[nobody2000]

ok what program can I use to resize it to the vertical and add bars?

[lumis]

main concept mpeg encoder can do this.. i've done it with a few xvid files.

[iThinkYouBrokeIt]

I would use TMPGEnc and use the "center - custom size" option.
select the NTSC DVD 16x9 profile, and center the image at 720x363. this is the resolution which should be used to center a 2.35 image within a 16x9 dvd-rez frame.

if your source file is MPEG-2 then you may need to use DGIndex so that TMPGEnc can read it.

yeah . . .

[manono]

Yeah, but he's not doing it for an 1:1 AVI, but for a 16:9 DVD.

You've brought at least part of the problem upon yourself by using the terminology incorrectly, lumis.

As I understand it, originally it was a 2.35:1 movie encoded as 16:9. Some idiot got ahold of it, cropped away the black bars to make it 1.78:1, and then reencoded it as 16:9, making everybody look tall and thin, and turning circles into ovals. 16:9 is a DAR (Display Aspect Ratio) only, and it tells the player how the movie is to be resized upon playback. 2.35:1 and 1.78:1 (as well as 1.85:1, 1.66:1, 1.33:1, etc.) are movie ARs.

Anyway, now you want to know how to add back the correct amount of black bars so it plays with the correct Aspect Ratio again. This may or may not be exact, because that same idiot that cut away the black bars may also have messed up the AR in other ways (by cutting into the video, for example), but I'll take your word for it that it's really 2.35:1, even though most so-called 2.35:1 movies are really wider than that.

Do you know AviSynth? First make a D2V project file using DGindex set to ForceFILM. Then make your AviSynth script file like so:

LoadPlugin("C:\Path\To\DGDecode.dll")
MPEG2Source("C:\Path\To\Movie.d2v")
AddBorders(0,58,0,58)
LanczosResize(720,480)

If you've used AviSynth before then you should aready know about the colorspace conversions necessary for TMPGEnc or certain versions of CCE. If you haven't used it before, and prefer to frameserve with VDub, then I guess you can add the black from inside of VDub. That script adds 58 pixels of black to both the top and bottom. You then reencode to 16:9, and when done you'll have your 2.35:1 movie.

if your source file is MPEG-2 then you may need to use DGIndex so that TMPGEnc can read it.

He said the source is a DVD, but I think your method works also.

[manono]

I was thinking about that some more later on, and decided that IThinkYouBrokeIt's resize before the AddBorders in TMPGEnc is right (although I think you should resize by even numbers). My script before is incorrect. Make it:

LoadPlugin("C:\Path\To\DGDecode.dll")
MPEG2Source("C:\Path\To\Movie.d2v")
LanczosResize(720,364)
AddBorders(0,58,0,58)

I think all that Nobody2000 was looking for was an easy program and some numbers to compress the vertical resolution using black bars like how you see in some Anamorphic DVD's with 2.35:1 ratios.

I would think that TMPGEnc would be perfect for it. As for the raw numbers to set to get the black bars in the proper "aspect ratio," I don't really know.

But what I would suggest is capturing a bit of a 2.35:1 Anamorphic DVD in 16x9 mode (not 4:3) and importing it into TMPGEnc. Then see how many pixels it takes you to crop out the black bars, and then essentially reverse the numbers to add the same amount of pixels to your screwed up video.

As for the encoding time, that's pretty much entirely based on how fast your processor is. Making any changes to video, whether resizing or video effects (brightness/contrast) is going to add emensly to encoding times.
