<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I was wondering about the reference buffers used in the
motion estimation algorithm for the Test Model of h264 as well as X264. Does
X264 and the Test Model JM10.1 used the reconstructed reference Y buffer or the
original reference Y buffer to search for Motion Estimation. I know H263 uses
the reconstructed reference Y buffer but I think Mpeg2 used the original
reference Y buffer. I know all specifications don’t provide guidelines
regarding this matter. So I was wondering what was decided when implementing
the JM10.1 and X264.<o:p></o:p></span></font></p>
