Two Pass Encoding

Hi,

a little question about two pass encoding that flyes in my head from a 
long time:

In the first pass of a two pass encoding is necessary give to transcode 
program all the parameters of final transcoding?

For example, if I have to transcode a video that needs some filtering 
and resize, in the first pass is mandatory to give all the options, like 
bitrate, resampling, filtering etc, etc?

Thanks a lot! :)

ciao.

	Fabio.
