PAL DVD to NTSC Conversion

[Sexybeast]

What is the best way to convert a PAL DVD to NTSC? The problem I am having is that I have a PAL DVD rip. I use IFOEDIT to change the rip to NTSC. The problem is that when I change to the NTSC format and play the DVD(in IFOEDIT), 3/4" of the screen has a green tint over it. When I play the PAL rip there is no green tint. Any suggestions on what I'm doing wrong?

I would burn it to an RW disc and just check it on your player. It could be the built in preview that is actually having a problem.

That's how I first noticed it was on my DVD so I started inestigating and found that the NTSC preview has the green tint too...

If the problem shows up on your disc, then the next place I would look, would be your MPEG decoder codec. Try a different one and see if the problem still exists. Fortunately, you can just unstinstall, and re-install as needed, previewing each to see if the problem goes away.

Sexybeast, I am interested in doing some PAL to NTSC conversion also, but I don't have much clue on how to use INFOEDIT. Any pointers be appreciated.

Chinoman, you shouldn't hijack someone's thread like that. Post your own topic out in the main forum, and you'll get many more responses than you would here

I am curious as to how you changed PAL to NTSC with Ifoedit.
Didn't you resize and re-encode ?

Not sure why it works but doing this CAN work with many DVD players. You simply change the IFO files with IfoEdit to read NTSC instead of PAL

The problem is that the image tends to be a bit "jumpy" looking etc.

It's far from perfect.

I tried it a couple of times a long while ago ... not a method of "conversion" I would recommend.

DJRumpy, thanks for the "reminder". My last entry in this thread.

FulciLives, thanks for the pointer.

FOO, this is the 'patch' method of converting to/from NTSC or PAL. You just go in and specify in the IFO that the DVD is actually using NTSC resolutions, rather than PAL. You also specify that it should use an 'Automatic Letterboxing' method. The video is scaled in playback so the vertical fits properly.

Depending on how good your DVD playback hardware is, you can get either excellent results, or you get the jaggies on vertical lines. Some of the cheaper hardware scalers can look pretty bad using this method.

It also had the drawback, in my tests, of not automatically resizing your DVD menu's (could have been my player that failed to do this..not sure here), so if you have any buttons that are close to the edge, they will be scrolled off the screen.

This is exactly what I did. I changed the information in the IFO from PAL to NTSC. When I then play the DVD back, I get this green tint over the picture. I'm now starting to understand that this is not the best way to convert. Does anybody have any suggestions what is the best way to convert PAL to NTSC?

Two choices :

1) Follow the link above posted by Fulcilives

2) Buy Canopus Procoder

Quite a few more choices than that

Just check the GUIDES section. There are tons of options for converting. The patch method we were discussing above, is just one of them. It tends to be the easiest (read: lazy 8) ) method, but it may not be compatible with all players, as you've already found.

Converting from PAL to NTSC will usually involve slowing the video down from 25 fps to 23.976 fps (ntsc film). If the video is was made in the US, then you are actually restoring it to it's originl framerate ( a good thing ).

You can also use a telecine method to just telecine the video from 25 fps to 29.97 fps. Xesdeeni came up with it a year or two ago (I think that method is simular to the one Fulci is referncing). It all depends on your personal preference. I'm somewhat of a perfectionist when it comes to this sort of thing, so I take the slowdown method.

You can use any encoder to do this, as long as you slow the video down or telecine it. Some encoders will do this for you, like TMPGenc, while others require you to slow it down before hand.

Read the guides section, and find one that looks good to you.

DJ,

Do you have a guide that explains the Ifoedit patch method ?

Of course I know it isn't perfect, but I'd like to take a look at it anyway;

I've searched this site guides but haven't located it;

Thanks,

I'll throw one together. Today is EXTREMELY slow at work
