Hi All,
I have been trying to convert some of my old PAL VHS tapes to NTSC
DVDs before they completely die. I have a DVD recorder which can
create a PAL DVD from the PAL VHS input signal, which I can then bring
into the computer using vobcopy.
I then use the following transcode command to generate separate m2V
and ac3 video and audio streams in NTSC format:
transcode -i tmp/movie.vob -y mpeg2enc,raw -x vob -D -2 -Q 5,5 -F 8 -Z
720x480 -n 0x2000 -E 48000,16,2 -b 256 --export_asr=2 -o tmp/movie -m
tmp/movie.ac3 -J
smartdeinter=diffmode=2:cubic=1:blend=1,modfps --export_fps 29.970,4
This works OK, and then I use mplex to recombine the video and audio streams.
mplex -f 8 -o tmp/final.mpg tmp/shrinked.m2v tmp/movie.ac3
The resulting final.mpg file is playable on the computer, I can
successfully create the xml file for the DVD writer using the makexml
command,
makexml tmp/final.mpg -dvd -overwrite -chapters 5 -out tmp/movie but
when I try to make the DVD using
makedvd "tmp/movie.xml"
I get a succesion of messages like the ones below
WARN: Discontinuity of 4320 in audio channel 8; please remultiplex input.
WARN: Previous sector: 94.021 - 94.021
WARN: Current sector: 94.069 - 94.069
WARN: Discontinuity of 6480 in audio channel 8; please remultiplex input.
WARN: Previous sector: 94.069 - 94.069
WARN: Current sector: 94.141 - 94.141
The resulting DVD is playable, with decent video, but no sound.
Is there anything in the transcode or mplex commands that I could
change to avoid the makedvd errors?
Thanks
Jeff
PS I do know that there are US spec DVD players that can play PAL DVDs
on an NTSC TV. I have one myself, but I'd like to convert the DVD so
that special players are not required.
