 ...and the native encoder mpeg4:

ffmpeg -i input.avi -c:v mpeg4 -vtag xvid output.avi

The native encoder has the advantage of not requiring an external
library. Both encoders should provide a similar output, but for lower
bitrates/quality (e.g. 1000 kBit/s for 720p content), libxvid will
deliver better quality than mpeg4.
