Hi

I am attempting my first video conversion using ffmpeg on Ubuntu Feisty.
Tried converting a wmv to avi in the hopes of producing a divx/xvid file.
I converted but the output video is very jumpy. Input video was fine.

I am very new to video formats and the technical language of it all so simple suggestions would help me.
This is the command and output of what I tried.

ffmpeg -i inputfile.wmv -ab 128 -b 1200 outputfile.avi

Seems that stream 0 comes from film source: 1000.00 (1000/1) -> 1.17 (7/6)
Input #0, asf, from 'inputfile.wmv':

Stream mapping:
