Here is how it works, and how to use it:
.br
The first pass (vpass=1) writes the stats file.
You might want to deactivate some CPU-hungry options, like "turbo"
mode does.
.br
The second pass (vpass=3, that is not a typo ;-) ) reads the stats file and
In two pass mode, the second pass (vpass=2) reads the stats file and
bases ratecontrol decisions on it.
You can use all encoding options, except very CPU-hungry options like "qns",
.br
The third pass (vpass=3) does both.
It first read the stats then overwrite them (You might want to backup
divx2pass.log before doing this if there's any possibility that you'll
have to cancel MEncoder).
In three 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'll have to cancel MEncoder).
You can use all encoding options, except very CPU-hungry options like "qns".
.br
The third pass (vpass=3) is the same as the second pass, except that it has
the second pass's stats to work from.
You can use all encoding options, including CPU-hungy ones.
