PAL DVD to NTSC DVD w/ 5.1

[lemmy999]

This is what I have come up with so far. Is there anything step here that is obviously stupid and either won't work or is not needed? Thanks

1. DVDDecrypter to get VOB files (4 of them total)
2. DVD2AVI to get .AC3 and video file TMPGEnc can open
3. Use BeSweet to get 6 WAV files from .AC3 5.1 file
4. Use Cooledit to stretch each WAV file by 25/23.976 = ~4%
5. Use SofteEncode to encode 6 stretched WAV files to 5.1 .AC3 file
6. Use TMPGEnc and load the video file, choose 23.976fps and “Do
Not Frame Rate Conversion” to get a 23.976fps file (is this
the best method of changing the frame rate from 25 to 23.976?)
7. Repeat all above for each VOB
8. Merge all 4 video files into 1 MPEG file (because SpruceUp
needs 1 big file instead of separate ones).
9. Use pulldown.exe to set the proper flags 3:2 pulldown flag to
the video file (so Spruceup won’t complain about it not
being 29.97fps)
10. Use spruceup to make menus and export
11. Burn to my DVD+RW drive using ????? (maybe Nero)

Would it be better (or is it possible) just to do all of this using ifoedit and vobedit and just demux, make the changes to the audio and video and remux, and keep the original menus?

lemmy:

It's been a couple months since I converted pal to ntsc, but if I remember correctly, your steps seem logical / correct.

Just a thought. Why not append the VOBs together and then to the conversion. It seems that would save some time. That is assuming you do not want to keep the menu structure.

Just a thought.

Yeah, I guess it would make more sense to append the VOBs first.

Is there any way to change the framerate of the .m2v file without actually reencoding it with TMPGEnc?

Yes. You can use pulldown.exe to change the framerate. However... You'll probably find that the vbv values will be shot and you'll end up with stutter. Plus, you need to resize the video to 720x480.

When I do pal->ntsc conversions, I load the m2v into avisynth and resize to 720x480 and then use AssumeFPS(23.976). I can feed the final result into CCESP without problems at that point.

I am not really using pulldown to change the framerate. I just want to create a 23.976fps file from a 25fps source. Even when you set the flag to perform 3:2 pulldown on playback in TMPGEnc, SpruceUp will not take the resulting m2v file. So I was just hoping pulldown.exe would set this flag (that TMPGEnc is apparently not doing) so that SpruceUp would accept it as a 23.976fps file that will be played back at 29.97fps. I don't really understand why pulldown.exe would screw up the vbv values. What kind of m2v file will I get using AVISynth? Will it be a 23.976fps m2v with the 3:2 pulldown flag set? I was under the impression that AssumeFPS will just drop 1 frame/second making the result a little jumpy. Thanks.

You're going to have to re-encode -- you need to resize the stream to 720x480 before anything will accept it.

Here is what I'm doing (this is my first Pal to NTSC convert but I've done alot of searching for info)

Software used:
CCE 2.50
Avisynth 1.07
MPEG2DEV plug in for Avisynth
DVD2AVI
Smartripper
Pulldown

1. Use Smartriper and demux audio and video (video into 1 or 2 files depending on size, it will split at the 4gb point)
2. Open DVD2AVI load your video file(s) and save as a project (in this example Spidey.d2v).
3. Create a Avisynth script using note pad and save it with an AVS extension (make sure file type is set to *.*).

This is my script:

LoadPlugin("C:\1perfect dvd\mpeg2dec\MPEG2DEC.dll")
Mpeg2source("C:\Spidey\spidey.d2v")
AssumeFPS(23.976)
ResampleAudio(44100)

4. Open CCE 2.50 and load the AVS file and encode (see Doom's guide for using CCE)

If you elect to use TMPG then remove the "ResampleAudio(44100) line.

5. Use Pulldown

Pulldown spidey.mpv spidey2.mpv

if your source is interlaced and you experience flicker when you are done then try this

pulldown.exe spidey.mpv spidey2.mpv -tff even

or if you have already used pulldown then use this

pulldown.exe spidey.mpv spidey2.mpv -nopulldown -tff even

Thanks MickeyNBK. I have a few questions. Why do you use the ResampleAudio for CCE and not for TMPGENc? Are you making a (s)VCD or a DVD? Where are you resizing the the video so it will be XXX x 480 (maybe in CCE?)? Where are you slowing down the audio by 4% so that it will still be in sync with the video when you put them back together?

When I make an SVCD I always perform IVTC and then have NTSC(film) at 23.976fps and in TMPGEnc I set the flag so the player will do pulldown when it plays the file. However, I have heard of people doing that with TMPGEnc for DVD and SpruceUp won't accept it because it is 23.976 instead of 29.976. Does pulldown.exe just set the flag so the player will do pulldown when it plays the DVD, or does it actually do the telecining (ie duplicating certain fields and making the file larger)and make the video truly 29.976fps?

[MickeyNBK]

For some reason CCE won't accept the AVS file until I add the line for ResampleAudio. TMPG accepts it without that line. The line does nothing except allow CCE to use the file. I'm making a DVD and using Maestro to author. You have to use an audio editor like cool wave to streatch the audio but not the pitch. If you try to use TMPG or CCE it will lose sync. Pulldown doesn't make the file larger so it must just set the flag. I don't use SpruceUp so I don't know what the results would be. Since DVD Maestro is made by Spruce I would imagine it would still work. I havn't had the files rejected by anything yet.

To adjust the size add this line to your Avisynth script (avs file)

BicubicResize(720,480,0.00,0.75)

that works for full frame anyway, you may have to adjust it for anamorphic video.

so you should have

LoadPlugin("C:\1perfect dvd\mpeg2dec\MPEG2DEC.dll")
Mpeg2source("C:\Spidey\spidey.d2v")
AssumeFPS(23.976)
BicubicResize(720,480,0.00,0.75)
ResampleAudio(44100)

[lemmy999]

Thanks for the help. I would like to try Maestro, but I don't have that kind of cash :( I am using Cooledit to stretch the audio, then SoftEncode to create the AC3 so the audio sync problem in TMPGEnc won't be a problem. I have heard audio is sped up by 4% to get PAL, but I don't know if that is always the case. If so, then I will not want to keep the pitch. Thanks again for your help. I think I have a good plan of attack for my first PAL DVD.

MickeyNBK i fallowed your steps and everything was fine till i try to import it to maestro
Import media asset :
Error: illegal picture resolution (0xc10a00b)

What do you do with the audio ?
