Comment:

 Please provide a command line and complete, uncut console output for all
 (non-build) reports on this bug tracker!

 (You do know that FFmpeg contains a native MPEG-4 ASP encoder that is not
 known to be worse than xvid?)

 What happens if you (slowly) increase the thread count? With the native
 encoders, you have to use a higher thread count than the number of cores
 you want to use (same as make -j).
 For me, -vcodec libxvid -threads 8 uses many threads, but it significantly
 hurts performance over -threads 1.

 In case I understood correctly that you are writing down your experience
 somewhere:
 Please note that 0.7 uses a deprecated syntax that gets outdated, you
 should definitely use current git head for tutorials and similar.
