Question about DVD chapter menus

[jsoto]

Hi blu,
I was expecting your welcome smile....

Kind regards, my friend.

How would I go about doing a 3:2 pulldown keeping the movie's total time the same as the original NTSC one? Here is the scoop: The movie was made in NTSC. I own the NTSC DVD, but it is fullscreen. I also have a PAL version, and it is widescreen. Since it was made in NTSC, the studio had to speed it up by 4% (the infamous "PAL Speedup"), so it has a playing time slightly less than the NTSC one. When converting to NTSC, how do I keep the time the same? (Sorry if that confused you!)

May you continue to visit us and educate us frequently.

Any idea how to do the 3:2 pulldown WITHOUT the file being an AVI? benbryant's method makes an MPG file, and the other program I use, DivX2DVD, just uses the VOB.

If I understand well, your interest is to recover the original lenght, isn't it?
Well, recoding the video (with avisynth) its simple: use "assumeFPS".
Without recoding, honestly I don't know if DGpulldown can do it. As I said, in PAL we cannot use these tricks...

Hmmm... jsoto, I used benbryant's method to convert, which I am not sure what it does. Here is a link: http://forum.digital-digest.com/showthread.php?t=56599

If the PAL to NTSC guide doesn't work for you, you can follow jsoto's excellent suggestion. You need to add:

AssumeFPS(23.976,True) and
LanczosResize(720,480)

To slow down the video and then apply the 3:2 Pulldown to 29.97. After that, you can speed up audio by using GoldWave to keep video and audio in sync

Quoting myself..., you always need re-encoding... at least you need to resize which is not possible w/o re-encoding... (although I believe there are some transcoders able to resize, but not to all possibilities)

So, you need to use a MPEG-2 encoder. You options are:
- AssumeFPS, recovering the original length (needs correction on the audio/subs before muxing)
- DGPulldown. The length will be the same (the speedup one). No needs audio/sub correction.

Quality on both options is, more or less, the same.

Or buy a dual format player!

Does it need to be an AVI file? If so, how do I make one without losing quality?

And I have a dual format player, but then if I take the DVD to a friends house to watch, it won't work. I want the actual DVD converted.

So, you need to use a MPEG-2 encoder. You options are:
- AssumeFPS, recovering the original length (needs correction on the audio/subs before muxing)
- DGPulldown. The length will be the same (the speedup one). No needs audio/sub correction.

So, how would I fix the audio and the subs?

IMHO, The best 2 methods for converting PAL to NTSC is to slow the movie down to 23,976 fps, apply 3:2 pull down to 29.97, and speed up the audio with an audio editor. Use Canopus Procoder 2 which also produces great result for PAL to NTSC conversion. Or like blutach said: "Or buy a dual format player!"

A friend of mine has Procoder, but I tried it at his house and it crashed each time I tried to encode. As for an audio editor, could I use the original audio from the fullscreen and the subs as well, since the times would then be identical? As for getting the speed the same, I still need to know how to do that.

[blutach]

Is it Procoder 2 drf? That does the job no questions asked.

Regards

[drfsupercenter]

I think so. Not sure exactly, but I think it was Procoder 2. Also, there is no free trial of it, so I can't really try it without paying 100 bucks for it.

[blutach]

Procoder 2 is a lot more than $100.

Either way, I don't even have that much money to spare! I need a free method, the AVIsynth looks good, but I am not sure how to use it.

Well, off to watch Batman Begins. See you all tomorrow!

Finished watching Batman Begins. Very good movie (I have the 2-disc collector's edition). Any suggestions now about converting the movie so that the NTSC original and the PAL converted to NTSC have the same number of frames, thus being the same length?
