title: fast encoding video codec?
body: <p>can anybody compare popular video codecs by encoding speed? I understand that usually better compression requires more processing time, but it's also possible that some codecs still provide comparably good compression with fast encoding. any comparison links?</p>
  
  <p>thanks for your help</p>
  
  <p>[EDIT]: codecs can be compared by used algorithms, regardless of its particular implementation, hardware used or video source, something like <em>big O</em> for mathematical algorithms</p>
