Look on your nandub directory.
There is an 'example.ecf' file
which explains all you can do with ecf.

you can use something like that

@135, D, CL=3
To force the (key)frame to be encoded as a delta frame with a drf of 3.
It can help sometimes when you have luma inverted block on the frame, and a drf of 2 used for the frame.

I think one goal of the ecf is to correct spotted errors:
* coming from the encoder
(luma blocks appearing at drf 2 sometimes 3 rarely 4),
* coming from too low bitrate allocated on some scene,
( using @135-145, R=2000 #for example )
* correcting possible dropped frame
( tweaking until you got the problem solved)
* etc.
( anything you can correct with it...)

oh i find this file very helpful :D :D
thank you i will probably write a program that will edit this huge file as doing it manualy is a pain :P
if any one has allready wrote a program that takes commands and edits an ecf file (Gknot only does keyframe/delta and states motion chcange on the 0-299 scale relative).

if not one day i'll write a simple one and post it in this forum

and btw do the commands here allways(100% of the time) overide the nandub settings like is nim BR in nandub is 410 and i set R: 300 will the BR for that frame be encodec at 300kbps or 410??

thanks for all ur help guyes

as far i looked on nandub source

antishit override ecf.

other settings are overriden by ecf.

Meaning if the setting you pass via the ecf won't produce
a 'correct looking frame' according to the antishit settings,
the antishit will act and will probably kick out your settings.
