View Full Version : Feature Suggestion: PAL to NTSC made easier!

Now that DVD2SVCD is back (woohoo! :)), I was thinking about this...

I've been reading over in the "Other MPEG1/2 Encoders" forum, and it seems that neuron2 (god bless that man) has made yet another very useful tool, and that is to run a customized pulldown so that progessive PAL (25fps) video or other common framerate video (23.976, etc) can be played back on NTSC DVD players without having to re-encode the video!

so what is the point?
this makes it so that if you want to convert a PAL to NTSC DVD, the only thing you need to do is:
1) Rip the DVD
2) Run through DGIndex
3) Resize the MPEG (from 720x576 to 720x480, keep the video @25fps/Progressive)
3) Run the resulting file through DGPulldown (modified version of pulldown.exe)
4) Author DVD

No use to even mess with the audio! It has been tested and it has worked for all test cases that I know of!

I was hoping that this could be incorporated into DVD2SVCD for those who do DVD to DVD (movie only).

For more info, see the pulldown thread here:

I was like the Secretary that just jotted things down. Oh, I suppose I did develop the parsing and the first implementation of the flagging, but overall it was a great team effort.

Sounds great. It would be a great feature to put in DVD2SVCD. I've always just used the MainConcept encoder to convert downloaded PAL DVDs to NTSC, and works great but if I could use DVD2SVCD and CCE that would be even greater :)

Original material: VOB ripped from DVD, video in PAL format. Audio track is LPCM only.

I have been successful in getting much of this to work, but I am stumped at one of the last steps.

I have produced a resized m2v video file. This was produced by using first, DGIndex and an AVS script frameserved through TMPGEnc. I have checked, and it is properly resized to 720 x 480. DGPulldown has then changed the framerate to 29.97. Checked - this is done.

When DGIndex ran, it split the audio out to a 48Khz WAV file.

Now I need to figure out how to put the audio back together with the resized/reframed m2v. TMPGEnc says that it cannot mux a PCM file into the stream.

How do I get the audio back in to my converted file?

Can't you just give the M2V and the audio file to your DVD authoring program?

Otherwise, perhaps convert the audio to MP2.

I tried feeding them to the authoring program. The audio and the video were are out of sync.

For the first chapter of the DVD, for example, the audio ends up being 3:39.8 seconds. The video is ~ 3.46 seconds. Do I need to use Goldwave timewarp to stretch the audio to 3.46?

Problem found. It would be helpful if when running DGPulldown, to specify that the framerate of the original material was 25 fps.

The default, when you start DGPulldown is 23.97fps. I had left this setting at the default. It must be changed to 25 fps.

All is fine with audio/video sync now.
