Dear all,<br><br> I'm Dr. Vatolin, Graphics & Media laboratory of Moscow State<br> University (MSU G&M Lab VideoGroup). VideoGroup in our laboratory<br> working in area of video compression also (see for example
<br> <a href="http://compression.ru/video/ls-codec/index_en.html">http://compression.ru/video/ls-codec/index_en.html</a> ). Last autumn we<br> have started a small research project "x264 improvement" to analyze
<br> x264 sources. Now we have first results!<br><br> We make a big amount of measurements to find where codec can be<br> improved (first of all RC of codec). Most code is very good, but<br> finally we found such place. We replaced "start_qp" predefined
<br> parameter with function of target bitrate. It allows codec to predict<br> first frame size more precisely. The improvement is significant at low<br> bitrates with relatively short sequences. In our tests we outperform
<br> original version of codec (sources 02.12.06) up to 2 Db.<br><br> More detailed information (including modified sources, binaries and examples)<br> can be found here:<br> <a href="http://www.compression.ru/video/x264/x264_improvement_en.html">
