 Here is how it works, and how to use it:

 In two pass mode, the second pass (vpass=2) reads the stats file and
 bases ratecontrol decisions on it.

-In three pass mode, the second pass (vpass=3, that is not a typo)
+In N-pass mode, the second pass (vpass=3, that is not a typo)
 does both: It first reads the stats, then overwrites them.
 You might want to backup divx2pass.log before doing this if there is
 any possibility that you will have to cancel MEncoder.
 You can use all encoding options, except very CPU-hungry options like "qns".

+You can run this same pass over and over to refine the encode.
+Each subsequent pass will use the stats from the previous pass to improve.

+satisfied with the encode.
