Converting PAL-->NTSC

[Glide]

Hello Everyone,

Is there any easy way of converting a PAL SVCD into a NTSC SVCD? I have looked at the tutorial on dvdrhelp.com to convert the fps and it is a fairly long process. I just wanted to know if there were any other ideas.

Thanks.

Run the SVCD through DVD2AVI/DGIndex, this will demux mpa audio and join the video as a single D2V. If there is any overlap, do each part seperatly though.
Next create an AVISynth script something like:
video = mpeg2source("PAL.d2v").assumefps(23.976).lanczosresize(480,480)
audio = mpasource("PAL.mpa").TimeStretch(tempo=(100.0*23.976)/25.0)
audiodub(video,audio)

If you do have overlaping parts then something like:
vpart1 = mpeg2source("part1.d2v").trim(0,4864)
vpart2 = mpeg2source("part2.d2v").trim(50,0)
video = vpart1+vpart2

You should then just be able to encode your AVS as your source and get a NTSC SVCD compliant MPEG. You will need to do a 3:2 pulldown though either during or after encoding as I understand that NTSC SVCD specs only support 29.970fps.

Any way of converting it from a dvd or vob or do you need to convert to svcd before you can change pal to ntsc ?

Basically the same, except you run the ripped VOB/M2V through DGIndex and because the audio is most likely 5.1AC3 you would do it seperatly. Also the resize would be different.
