[Mjpeg-users] Converting DVD from PAL to NTSC

[Greg K. <gr...@ki...>]

Hi,

I live in the U.S. and received a PAL DVD from family back in Australia.

I want to convert the DVD from PAL to NTSC and burn a new DVD (it's less
than 4.7GB).

I've played with a number of different tools including: mplayer,
dvdbackup, dvdauthor, transcode, mjpegtools; but I can't find the right
combination yet.

I had a small success with the following sequence:

mplayer -vo yuv4mpeg -nosound -noframedrop dvd://1
cat stream.yuv | yuvfps -r 30000:1001 | yuvscaler -O SIZE_720x480 | 
  mpeg2enc -f 9 -q 1 -b 5000 -n n -o ntsc.m2v
tcmplex -m d -d 3 -D 0 -o x.vob -i ntsc.m2v -p x.mpa

The x.mpa file came from an earlier run of transcode which was called
out of the dvdbackup script.

I'm fine with getting the .vob file onto a dvd using dvdauthor and
dvdrecord.

For the small test I did, the movie was jerky. I don't know about the
sound because the title I used had no sound.

Can I use mplayer to extract both the video AND the audio?

Any idea on why the movie is jerky?

How can I know if the source is interlaced (or are DVDs never
interlaced) and thus perform a de-interlacing step?

Cheers, Greg.
