[MPlayer-users] Horrible Compression Artifacts in High Motion Scenes

Hello. I'm attempting to compress a video with the following command  
line:

mencoder INPUT -o OUTPUT -nosound -ovc lavc -lavcopts  
vcodec=mpeg4:vpass=3:aspect=16/9:idct=8:trell:vmax_b_frames=0:vqmax=31:v 
hq:v4mv:vrc_eq=tex:vfdct=5:dia=-1:vbitrate=1200:vrc_minrate=650:vrc_maxr 
ate=2500:vrc_buf_size=1835 -vf  
crop=720:464:0:8,filmdint=dint_thres=256,pp=lb -ofps 29.976

My guess was with that kind of a bitrate, there would be enough  
information to compensate for high-motion scenes (which this video is  
full of). Instead, the result was that virtually all high-motion  
scenes are flooded with compression artifacts. Scenes with repetitive  
motion (the same background repeating) or even as simple as following  
someone running comes out with blocking everywhere. Low motion scenes  
are crystal clear, but high-motion scenes (which make up the bulk of  
the video) do not, even after three or four passes. Any ideas on  
what's going on, or how to fix it?
