That depends most likely on the default output quality. You can
increase the output bitrate or the quality to fix that, use a
different lossy codec with a better quality/compression ratio (AVI
assumes MPEG-4 part 2 by default, but you can change that through the
-vcodec option), or use a lossless codec.
