title: Direct Show Decrease Video File Size
body: <p>I am using direct show to capture video and save it to file.  I have tried in vain to find ways to decrease the resultant video size but cannot manage.  I would like to know if anyone can tell me how I can:</p>
  
  <ol>
  <li>Decrease the frame rate of the video</li>
  <li>Decrease the quality of the video (even down to 320 x 240)</li>
  <li>Apply a compression on the video (mpeg? etc).</li>
  </ol>
