title: VirtualDub AVI Compression
body: <p>I am using VirtualDub to output compressed AVI files from input JPG files.  I choose</p>
  
  <p>Full Processing Mode</p>
  
  <p>as the video mode and</p>
  
  <p>Cinepak Codec by Radius</p>
  
  <p>I chose image quality of 100%, 50% and 10% but the output files are all the same size.  I would have expected the lower quality setting to produce smaller files.  Am I using it incorrectly?</p>
