Commandline 2pass with AVG bitrate

[mayday07]

Hello,

I used to convert my movies from camera using avidemux for some time.
setting up all these options over and over again was annoying, so i decided to try CLI.

after reading manual pages and some forums i found out there are following options for avidemux CLI video processing:
--video-conf, set video codec conf (cq=q|cbr=br|2pass=size)[,mbr=br][,matrix=(0|1|2|3)]  (one arg)

in the GUI however i found the option (which i was using usually) to use 2 PASS, and set the AVG bitrate rather than file size.

Could anyone help me - how to make avidemux process video using 2PASS, and set AVG BITRATE?

Thank you.


so far my script is:

#!/bin/bash
for fn in *.mp4; do
avifn=${fn%.*4}
avifn+=".avi"
echo "Converting $fn to $avifn..."
avidemux --force-alt-h264 --load $fn \
--audio-codec MP3 --audio-bitrate 128 \
--video-codec x264 --video-conf cbr=1200 \
--save $avifn --output-format AVI --quit
done

(i need to replace cbr=1200 with something.......)
