Can't encode 2-pass with Flaskmpeg and DivX 5

[BARiLLA]

Hi.

I use Divx 5 and Flaskmpeg 0.6 preview and I'm having
problems encoding my files with 2-pass.

1-pass works perfectly but when I set the codec to 2-pass
my output file is like 5 megs (and doesn't work), when it should
be more like 50.

Can't figure out what I'm doing wrong =). Help anyone?

With 2-pass encoding you have to do 2 passes, first the '2-pass first pass', then the '2-pass second pass'.

and before i lose 10 hours to try it ... :)

with 2-pass, what are the vantages and the disvantages?
[i mean, quality/size ...]

Better quality and more precise filesize prediction.
