This is useful when you need to convert some high resolution MKV video into an AVI file, in order to save space at the cost of quality. Say you have a Matroska video file, my_video.mkv. To convert it to AVI you can use mencoder (the command below is only one line):
mencoder my_video.mkv -ffourcc xvid -ovc lavc -lavcopts vcodec=xvid:vhq:vbitrate=1800 -oac mp3lame -lameopts vbr=5 -o output_video.avi
The resulted AVI file will be output_video.avi, located in the same directory as the source, and will have about 35% the size of the source file.

Don't work for me, it say that I have not the xvid codec and I have it
This does not work, just simply use this:
mencoder test.mkv -ovc lavc -lavcopts vcodec=mpeg4:threads=8:vbitrate=3000 -oac copy -o test.avi
ffmpeg -i test.avi -vcodec copy -vtag xvid -acodec copy final.avi
