== making a video ==

<pre>

sudo apt-get install gtk-recordmydesktop

</pre>

Run it. Select area to record, press Record.

Stop recording by pressing the square on the top right of your menu bar where the clock is normally.

Encoding takes a while.

Saves as out.ogv in your home folder by default.

Sound etc was okay on my netbook though it seemed to pick up the mic and you can hear typing.

Couldn't get sound to capture at all on my desktop.

Youtube didn't like the .ogv file. Said it was too long, it was 12 mins, 15 is max? maybe the problem is the format.

Convert to AVI:

<pre>

sudo apt-get install mencoder

</pre>

Use command as per [http://info123.org/tutorials/54-how-to-convert-ogv-file-format-to-avi-or-any-other-format]

<pre>

mencoder -idx out.ogv -ovc lavc -oac mp3lame -o intro_stendhal_201201.avi

</pre>

Weirdly the avi was 36 minutes but the original was 12, nothing happens after 12 minutes, weird? Trim to only keep the first 00:12:12

<pre>

mencoder -endpos 00:12:12 -ovc copy -oac copy intro_stendhal_201201.avi -o intro_stendhal_201201_1.avi

</pre>

following advice at [http://ubuntuliving.blogspot.com/2008/03/splitting-avi-file-into-smaller-parts.html]

Then google accepted it
