Thank you very much for your thorough and well written explanation. I just 
have one last question. In my experience, the lavc mpeg4 codec seems to have 
the most problems (visual quality wise) encoding scenes that 1) contain smoke 
or clouds (this is doubly true for dark scenes) 2) scenes containing large 
solid color areas. In both cases, the encoded video looks blocky even when a 
high bitrate or a qscale of 2 is used. Since I watch most of my videos on 
T.V., this is the type of visual artifact that I most want to avoid because 
its very apparent. Do you have any specific recommendations to improve the 
visual quality of these types of scenes.
