Hi all.
I have a mpg file and I'd like to make a VCD (a SVCD will be ok just the
same) out of it but I didn't succeed so far.
The file is a MPEG1 video 720x480 NTSC 29.97 fps 3750kbps (that's what
mplayer tells)
I demuxed it with bbdmux, and the video stream I got plays well.
Then to get a VCD format I tried several commands, none of them worked.
Here's the command I used (I played a lot with the options but that's
the basic command I've used)
cat video.m1v | mpeg2dec -o YUVh | yuvscaler -n n -O VCD | mpeg2enc -f 1
-o video_vcd.m1v
(I've also tried -F 1 -F 4 and -I 1)
When I try to watch the output video file "video_vcd.m1v" it's all
filled with colored vertical lines. Looks like the original video is
deformed.
At the bottom of this message there's the first part of the command's
ouput.
Maybe I'm messing something with the framerate (becomes 23.97, don't know
why); I really don't know where to start, the more I read the more I get
confused: any hint will be much appreciated.
Thanks in advance,
beatrice.
P.S. I wish to all of you a great 2003!!
