PAL to NTSC using cce and dvd2svcd?

[litlin]

I have searched and am ready to try the tmpGenc method of converting my PAL video to NTSC. But I have been using the DVD2SVCD and it has been working fine. I just want to know how to edit the avisynth script that DVD2SVCD will automatically generate and use so I can use CCE to do the PAL to NTSC conversion. I want to get the best possible quality.

Is this possible?
Thanks
Lit

Hi litlin

what you want to do ist not so difficult.
In dvd2svcd is a possibiliy implemented to edit the avisynth script it produces. You have to select advanced options for that.

What you have to do:
Just replace the resize from 480,576 to 480,480 and add a line like
AssumeFPS(23.976,true) (This is for progressive source).
After conversion you have to run pulldown manually.
For the audio part:
you can use besweet to change the Framerate of the audio. It can convert PAL-AC3 to NTSC-AC3, PAL-AC3 to NTSC-WAV, PAL-WAV to NTSC-WAV etc. Just look at the commandline-options.

Then you have to mux the audio and video.

Look in this thread (http://forum.doom9.org/showthread.php?threadid=24535) -> the video part is just ok, audio you should do with besweet now.

Let me quote:


" 2) The video part

So, you only have to change the *.avs scripts. For the pictures do a resize like for NTSC.

For the movie do a resize not to (480,576) but to (480,480) and add

AssumeFPS(23.976,True)

to the end of the script.

That convinces CCE to have a NTSC source.

The only other thing to do is to tell DVD2SVCD it has a NTSC Source. It should use the usual NTSC process to create the SVCDs (you know: pulldown.exe etc). That it won't do at the moment because the ifo says it's PAL.

Update 05/30/2002:
You have to apply the pulldown by yourself. That can be done the follwing way:
1) Wait till dvd2svcd has finished the process. But you cannot use the svcd images on your harddisk (they will play choppy 'cause of the missing pulldown.

2) Locate the Video stream tmpenc or CCE have created (it ends with .mpv). Run %DVD2SVCDROOT/pulldown/pulldown.exe %DESTDIR/%YOURVIDEOSTREAM.mpv %DESTDIR/pulldown.mpv

3) %DVD2SVCDROOT/bbmpeg/runbbmpeg

4) Klick on settings -> Input and Output files
Open PS: %DESTDIR/bbMPEG_Muxed_File.mpg
Open VS: %DESTDIR/pulldown.mpv
Open AS1:%DESTDIR/Encoded_audio_1.mp2

5) Program Stream Settings -> Program stream type: SVCD
Leave everything else untouched.

6) General Settings -> Multiplexing/start/stop/size options:
Enter 9999 into the field called End second and 795 (vor 80m CD)
or 735 (for 74m CD) into the field called Max size. Then press OK.

7) Press Start and wait, till bbmpeg has created your splitted muxed
video. Now you have the correct bbMPEG_Muxed_FileXX.mpg on your HD.

8) Now you copy the commandlines for vcdxbuild from your dvd2svcd log
into your cli (for every muxed video file there exists one to
create the corresponding image).

9) Volá. Now you have the correct NTSC-SVCD-images.
For interlaced source i don't know.
