Changing a 16:9 flag to a 4:3 flag in a VIDEO_TS folder

[deadsierra]

Okay, so I've got a DVD that was given to me by some idiot or other, who is very proud of the work he's done on it. Whatever. So, the issue is, he's thrown some letterbox clips on it, and then in a stroke of brilliance, told the DVD to play in 16:9 mode. So, the footage should be in a 4:3 aspect, with nice big black bars encoded into the video, but instead, its in 16:9, and producing some very nice fat people. Now, as far as I know, there is no original material left, only this DVD. So, is it possible to change all the video on this DVD to display as 4:3 material instead of 16:9?

Restream can do what you are talking about. You will have to demux the DVD video files into separate .m2v + audio files, but then Restream can save a new .m2v for you with the 4:3 flag without re-encoding. Then remux and/or author the new .m2v (with the 4:3 flag) with your audio file into a new DVD and you're all set.

Oops - just noticed you are a Mac user. I don't know if there is a Mac version of Restream. I think there is a Mac version of Pulldown.exe that may be able to do the same thing. I'm not sure, though. If you are able to use a friend's PC, Restream will definitely work, though.

Yes, it appears that PullDownX will do it. I used version 0.1, don't now if there is another version. I tried it on a 16x9 letterboxed .m2v stream I'm working on. QT and VLC opened the results as 4x3 letterboxed. mpgtxwrap is supposed to work also, I couldn't get it to work for me but I didn't spend much time on it.

This tool works on m2v's only? So I'll need to demux the vobs, work with it, and then remux?

As far as I know, the only thing that will change the aspect ratio of a VIDEO_TS Folder is IfoEdit, a PC program. And I'm not really sure about that. I've never done it. If you have VPC, some time to learn, and a desire, you can give it a try

maybe i can whip something up that will work on vobs for you.....bit busy right now with ** another problem ** but i think it should be quite easy to do....

.... more soon

Yep, it's REAL easy with IfoEdit. I just gave it a try. Double click, change 16x9 to 4x3, save. I did it in the VIDEO_TS.IFO and VTS_01_0.IFO files. It opens as 4x3 in DVD Player.

Geezer, it would truly be great if you would put that function in MTR

[galactica]

geezerbutz if you make something that parallels IFOedit for OSX i bet you will see your paypal ballance experience a [edit: i dont even konw what i mean] HUGE increase!

if thats what you are talking about perhaps making.........

woo hoo!!!!!!!!!

[deadsierra]

logarithmic? He should hope that it would be exponential.

Tugboat:
Where did you find PulldownX? From the conversation above, I'm assuming this is a Mac version of Pulldown.exe?

pulldown.... that rings a bell , ah yes, ported by BIFFA to OS X.... another of the buttz many previous names!

As Tugboat noted, IfoEdit can be used to change the aspect ratio in the IFO files. Does the aspect ratio also have to be changed in the VOB files? I'm trying to change from 4:3 to 16:9, and I can use IfoEdit to change the flag in the IFO files, but Bitrate Viewer shows my VOB files also have a flag set to 4:3. Do I need to change those too? If so, with what tool? Thanks.
