title: Converting .mp4 to .webm with FFMPEG
body: <p>Any chance someone can help me make this a 2 or 3 pass command:</p>
  
  <p><em>Using "FFmpeg Win64 Static build by Kyle Schwarz, compiled on: Sep 19 2012 16:31:43" in the Command Prompt of Windows7(x64). I am a newbie to FFMPEG and trying to convert videos for my website from <strong>.mp4</strong> to <strong>.webm</strong> (videos edited and mixed in AdobePremiereProCS6 where then encoded into <strong>.mp4</strong> from <strong>.mts</strong> Canon HXG10 recordings). Original video file is <strong>1080p</strong> quality.</em></p>
