I am trying to use ffmpeg to convert an AVI file to an MPEG (VCD). When I run the following command:


ffmpeg  -i movie.avi -target ntsc-svcd movie.mpg
Everything works fine, but the file size is bigger than a CD. I can't seem to find an option to compress the image. Does ffmpeg have this ability? If not, are there any other tools to accomplish this task?

You need to specify the bitrate; the default is 5Mb/sec, which is much higher than you need. For example:

ffmpeg -i somefile.avi -y -target ntsc-dvd -hq -aspect 16:9 -b 1800 somefile.mpg

The "-b 1800" specifies 1800 Kbps, or 1.8Mbps.

Thanks for the info.

Is there any way to easily backup a DVD in linux?

You can use DVDShrink, which is a (free) Windows program, but it runs under WINE. It has a very fast MPEG2 to MPEG2 transcoder, and can backup an entire DVD (all menus, subtitles, multiple audio tracks, etc.) in less than an hour. Tell it to generate an iso image on output (the only option that works under WINE), then use k3b to "burn a DVD iso".
