My questions is that even if I defind the GOP to be 30 frames, but from the result data streams, I saw that sometimes (very often), the gap between two I frames is less than 30 frames, I even saw 2 frames in between. is there a way, or configuration, to force that I frames only show up once in every 30 frames interval?<BR /><BR />Thanks.<BR /> Fri, 03 Sep 2010 21:04:18 GMT https://community.intel.com/t5/Intel-Integrated-Performance/UMC-Mpeg-4-encoder-question/m-p/830054#M5476 GrassValley_Eng 2010-09-03T21:04:18Z https://community.intel.com/t5/Intel-Integrated-Performance/UMC-Mpeg-4-encoder-question/m-p/830055#M5477 <P>could you please try with each frame to indicate it's type and then it will not be change.</P> Fri, 10 Sep 2010 05:29:23 GMT https://community.intel.com/t5/Intel-Integrated-Performance/UMC-Mpeg-4-encoder-question/m-p/830055#M5477 Gennady_F_Intel 2010-09-10T05:29:23Z
