title: How to quantify and compare video quality
body: <p>I have a set of uncompressed videos in YUV format. </p>
  
  <p>I have obtained several derived copies in various formats and resolutions from these yuv files using FFmpeg transcoding. (YUVs ----> X Derived Copies)</p>
  
  <p>What I have also done is, transcode the yuv's into same resolution AVIs, and now obtained the same set of derived (transcoded) videos treating the AVIs as master. (AVIs ----> X Derived Copies)</p>
  
  <p>Now I wish to compare the quality of transcoded videos, when derived from AVIs to those derived from YUVs.</p>
  
  <p>Is there any way for me to do this using FFmpeg. How? If not, can you please suggest some good open source software to do this.</p>
  
  <p>Thanks</p>
