I have been assigned a task that seems to be really hard for me.

I want to convert a video taken with iPhone4 (.mov) to a format that can be understood by Powerpoint (.wmv?)

I tried avidemux, but I don't know which is the correct format I must save the rotated file to.

I am using ubuntu 12.10


You can do it easily using ffmpeg.

If it is not already installed, install it using apt:

sudo apt-get install ffmpeg

To convert and rotate the file:

  • clockwise by 90 degrees:

    ffmpeg -i input.mov -vf transpose=1 output.wmv
  • counter-clockwise by 90 degrees:

    ffmpeg -i input.mov -vf transpose=2 output.wmv
  • By 180 degrees:

    ffmpeg -i input.mov -vf transpose=1,transpose=1 output.wmv

There are plethora of other options to configure. You can look and tweak them according to your needs, some options to consider closely would be the following video and audio options:

-c:v wmv2 -q:v 4 -c:a wmav2 -b:a 128k 

This will give quite reasonable video quality with reasonable audio quality in a relatively small file size...
