cropping a video 221:100?

[xsirxx]

Ive recently encountered a problem, I have a letterbox DVD and my sony projector wont crop it for me... SOOO question is, how do I go about editing a dvd or its video to crop the letterbox format and size it up to widescreen 16:9 format?

So incase I made no sense, how do I take a 4:3 letter-boxed DVD into a widscreen 16:9 format, in my VLC player I can crop it 221:100 to have it look correctly... how do I do this so the actual disc has the correct video(regardless of how blocky the video is).

Thanks!

DVD Rebuilder (http://dvd-rb.dvd2go.org/) can take 4:3 hard matte and convert to 16:9 anamorphic.

Hey thanks alot for the info, I went ahead and dloaded it, and tried it with CCE, unfortunatly it would not run. I went ahead and ran it as ReJig and although it ran it did not convert the 4:3 LB to a 16:9 WS.... I did click the box for it btw...

Has any1 used this before?

Thanks

EDIT: I did get it to work under another encoder(QuEnc) but a problem came up, the dvd video is stretched height-wise? Has any1 else encountered this?

That's strange - maybe report your problem in the DVDRB forum.

Are you sure the video is 4:3? Check the domain attributes in PgcEdit. If it is 16:9, you might be able to simply tick auto pan and scan.

Im not sure much about what that means, but IfoEdit says it is a 720x480(widescreen i guess?) and next to it, it says pan-scan and letterboxed... under those options Auto pan-scan is already selected, this is on the original...

Could ya help me understand that a lil more and will that change after the output from DVD Rebuilder, rebuilds it?

Thanks much!

If I understand correctly, your original movie is a false 16:9. It's a 4:3 "already letterboxed" picture. You can verify that easily with the Preview of PgcEdit: if the window has a 4:3 aspect ratio and you can see black horizontal borders, your movie is indeed encoded in 4:3.

To force the player to display it in 16:9, you can tick the "already letterboxed" option (With PgcEdit, right-click on the PGC and select Domain Stream Attributes.) That flag is supposed to force the 16:9 TV to zoom in the picture, and therefore hide the black bars. However, that flag is ignored by many standalone players.

If that doesn't work, you have to reencode in true 16:9. Of course, the reauthored movie must now have totally different domain stream attributes. Verify them with PgcEdit. The video must be in 16:9, and have at least one of the "automatic letterbox" and "automatic pan&scan" checkboxes enabled. Usually, for a normal movie, only the letterbox flag is ticked.
Take care also with the subtitles. They will probably not be at the right position any more. You can move them with DVDSubEdit.

[EDIT] If you want more help, load your original DVD in PgcEdit, and select Info -> Streams. Post the output here. Do the same thing with the reauthored DVD.

@r0lZ - seems from post 5, it is 16:9 auto LB and auto PS. But the player may not be panning and scanning for some reason.

What you both are saying makes alot of sense... basically the movie appears a fake 16x9... when I view it on my widescreen it shoes very little black bar on top and bottom. My computer dvd player(PowerDVD & VLC) both show the video as stretched by default.

After reencoding as a true 16x9 it appears to be stretched vertically still. This is with the pan-scan, letter-box, and widescreen all turned on and off. Even in combinations they ALL dont work. I have not tried to burn the disc yet, but I assumed that it would not run under widscreen on my home player if the computer player couldnt even play it correctly...

Would there be anything else that could cause this?

Thanks

EDIT: BTW I use IfoEdit, is that fine instead of this PGCEdit?
EDIT2: Also, if I force the computer player to push it to 221:100 it views perfect... but then I assume the original video was not 16:9 but this weird 221:100 res....
EDIT3: If I use TMPGEnc and cut the video sides off as well as the top and bottom black bars, forcing a 16x9 picture it runs fine, but I do lose the extra width of the picture unfortunatly....

In 16:9, at least one of auto PS or auto LB should be turned on.

But if the original IFO says it is 16:9, there is no need or benefit to re-encode it.

That's right. Your movie is a Cinemascope film or something similar. There are no video aspect ratio suitable for this kind of film. So, you must stick with the nearest aspect ratio available, which is 16:9. Of course, in this case, you cannot remove the black bars without reencoding and cropping also the left and right borders.

BTW, you can use IfoEdit to change the AR in the IFOs, but PgcEdit is a lot easier to use. It will change the AR is the VTS IFO and in VIDEO_TS.IFO in one operation, and won't let you input an illegal combination of flags (such as 16:9 without at least one of the LB or P&S flag.)
IfoEdit is still a very powerful tool to examine the IFOs, and it can do other interesting things as well, but I really don't like it to edit the IFOs.

Yea I kinda found that out unfortunatly.. :(. Well thanks alot for the help guys... I re-encoded it with cut off sides in TMPGEnc and I guess will use IFOEdit to go ahead and remux it?

Or r there better solutions?

Anyways thanks much!

[blutach]

I'd truly leave it in the original AR. I like to watch the whole of the video, not part of it.

Personal preference, but I regard P&S as a blight on the DVD landscape.

I understand completely, only problem I have is I have a widescreen projector and I hate light over shine on the screen. I also noticed that IFOEdit will not take video from TMPGEnc unfortunatly, so I need a way to cut the sides off with something that is IFOEdit able, or another program to do a ReMux....

Thanks much!

[r0lZ]

Use Muxman to remux. The free version is sufficient for simple tasks.

Ahahha ok now I need to be able to rip out the AC3 track from my dvd so I can input that into muxman :). Also useing that will cut out my menus right?
EDIT: also need to know how to rip chapters too from IFOEdit, cant find the damn button anywhere

[r0lZ]

Use PGCDemux to demux. Everything you need is there.

[xsirxx]

I load out the celltimes.txt and it only gives me 2 chapters inside MuxMan, on top of that I get an error when I try to put the new video and sound together, that error is:

"Multiplex Operation Failed: GOP contains 36 pictures at 773034 of (null)."

This is all a bit more of a problem I think than rather just watching over shooting light on a screen unfortunatly... this makes the process very long and running 4 different programs seems a bit excessive for a hour and a half of view pleasure heh.

Again thanks much EVERYONE for all the help!
