How to record a screencast

Thu May 20 18:25:58 MST 2010

Thought I'd start a new thread since Bryan asked about screencasting...

gtk-recordmydesktop worked the best of all the tools i tried.

You might be able to record sound and audio at once, but that didn't work on
my aging laptop. I found that recording audio and video actually worked well
as a workflow, aging laptop aside, because you can focus on actually doing
what your're doing on the screen, and then when you're playing it back, you
can sit back and tell people what you are doing.

So it takes a few steps.

First, record your screen with gtk-recordmydesktop. That's straightforward.

Then play it back and record an audio track. I used gnome-sound-recorder.
Then to put the two togetheri I used avidemux.

After you open your video with avidemux go to the "Audio -> Main Track" and
select the filetype you want to add (ie. external mp2/3, wav). Then select
the sound file and it should work. Maybe there's a quicker way to add the
audio track from the command line?

gtk-recordmydesktop outputs an ogv file, which avidemux won't open. so I
converted using  ffmpeg -i filename.ogv filename.avi. Then you can make the
final file a flv or whatever...

Here's what I ended up with:

Look forward to watching some screencasts on things like load-balancing!
