Inspired by the videos available on http://www.rubyonrails.org but
disappointed when trying to render the .mov format on my linux box,
I was looking at the instructions at
for doing a screen capture with ImageMagick and converting the stills
to mpeg.
Their 6 line bash script to create the initial series of stills became
3 lines of Ruby.
However, I'd like to automate the whole process of capturing, converting
to mpeg, and so forth. I started thinking that I should be using the Ruby's
ImageMagick binding, RMagick, etc.
Then I thought: I should just ask here because someone has probably
figured all this out already...
I have used VNC2SWF, with minor tweaking of configuration parameters
seems to do a good job.
It only runs on unices/Linux but since it works over the VNC protocol,
you can capture a remote Windows screen without any problem.
This is a screen capture I made in Linux, taking it from a Windows machine: http://vworkers.com/vruz/mov1.swf

Very nice hack! I put a Ruby script that does this with RMagick on
codepaste.org: http://www.codepaste.org/view/paste/232?show_comments=1
I used RMagick 1.6.0 with ImageMagick 6.1.0. I don't have the MPEG encoder
installed but I tried both MIFF and GIF formats. The resulting GIF file is
much smaller but takes a long time to write.
I could only get about 1 frame/sec (measuring with "1 Mississippi, 2
Mississippi...") and you're limited to the number of frames you can fit in
memory. That could be alleviated by capturing a relatively small window.

dunno if it helps, but mauricio fernandez has a script to build the animated gif on the rpa-base wiki that IIRC is done with RMagick, maybe you can ask him.

All of these technologies are really cool, but they are lacking
simultaneous audio capture. That would be really cool. I guess a
decent alternative would be to take the movie and dub a narrative
track in afterwards. Any suggestions for freeware video editing tools
that can do this?

Another project to mention is xvidcap / gvidcap, which can compress to
for instance mpeg4 on the fly directly from X11.
