by selecting a format as one of the options (”vcd”, “svcd”, “dvd”, “dv”, “pal-vcd”, “ntsc-svcd”), all the format options (bitrate, codecs, buffer sizes) are then set automatically.
You can just type:
$ ffmpeg -i myfile.avi -target vcd /tmp/vcd.mpg
#same example but use high quality, ntsc vcd format
$ ffmpeg -i myfile.avi -hq -target ntsc-vcd /tmp/vcd.mpg
#same example but dvd quality
$ ffmpeg -i myfile.avi -target ntsc-dvd /tmp/dvd.mpg
#same example use same quality as source
$ ffmpeg -1 myfile.avi -sameq -target vcd /tmp/vcd.mpg
#converting a file for VCD format using a and b frames for MPEG 2
$ ffmpeg -i myfile.avi -target ntsc-vcd -bf 2 /home/user/Video/vcd.mpg
#same conversion, but start at 0 seconds and convert only first 45 minutes
#use -ss for start position and -t for duration
$ ffmpeg -i myfile.avi -target ntsc-vcd -bf 2 -ss 00:00:00 -t 00:45:00 /home/user/Video/vcd.mpg
then you can use K3b to burn it to VCD or DVD.
