[P.Snot]

Hi

i'm trying my first steps in video encoding, using GKnot and following
doom9 directions.

Encoding in divx5 works perfectly.
However in xvid i get bad results.
First of all, the filesize was always wrong, and the bitrate too low,
drf values were going from 2 to 16 up and down with st dev of >10.
I checked 2nd pass xvid configuration, and there where gigantic
numbers in 2nd pass settings (eg 16248). Don't know how they got
there (I didn't touch them:)

So, I put in the values from doom9, but these settings are not in
their guide, but just in an example.
(http://www.doom9.org/index.html?/xvid-vdub-final.htm)
These new settings give the predicted file size, but the DRF values
are still too high with too much variation, especially because i use a
high bitrate & res in my testing purposes (1800kbit, 30b/pix).

Are there any directions for the right 2nd pass and quantizer values?
Isn't the codec supposed to find the optimal values itself after the
first pass?


thanks
