Hi, I ran a test of encoding a small file with various values of mbcmp,cmp and subcmp (ran a small script to do it and save results in a cvs file which I could use to plot a graph), of course with mbd=0. I found that with mbcmp=4,cmp=2,subcmp=2 the PSNR was the highest among various values of cmp and subcmp. Also the different values of mbcmp I tested for were all the ones mentioned in man page of mplayer(0-10). I used 2 pass encoding. Increasing the value of cmp and subcmp beyond does not make much difference but reduces the speed of encoding. I just wanted to ask this question in the subject and share my experience with other users of mencoder.
