[MEncoder-users] NTSC DVD to 25 fps MPEG

[Richard Bromley]

Hi. I would like to copy an NTSC DVD title to a single .mpg file,
preserving the original video and audio streams but changing the
framerate to 25. It goes without saying the audio rate needs to change
as well so that the audio stays in sync with the video.

The DVD video is film encoded in the standard way at, that is, the
majority is soft-telecined at 24000/1001 fps, with small
hard-telecined segments mostly at scene boundaries.

I have already tried the following:

$ mencoder -oac copy -ovc copy -of mpeg -ofps 25 -speed 25025/24000
-vf softpulldown,filmdint,harddup dvd:// -o dvd.mpg

No error messages are produced by mencoder, but the output file cannot
be played back with mplayer. The error message given by mplayer is
"MPEG: Missing video stream".

I have tried other commands, the resulting output files of which could
be played, but the decoder detected 24000/1001 fps progressive content
and switched the framerate back to 23.976.

Help is appreciated.
