A high-quality movie can be created using DX by

  1) creating a miff file
  2) breaking it into seperate frames that use a lossless
     format (e.g., GIF)
  3) using the MJPEG tools (mjpeg.sourceforge.net)
     to create an MPEG2 file.

The JPEG format you tried can loose detail unless you force it to its highest quality.

After step 2 all the files should be in one directory. Go to that directory and use a command like this to make the movie:

cat * | ppmtoy4m | mpeg2enc --format 3 --video-bitrate 5000 --motion-search-radius 32 --no-constraints -o mymovie.mpg

I don't know how to do this directly from DX. And, even if I did, I might not want to slow down my DX session with the MPEG encoding that occurs in step 3.
