[plug] Time Lapse Movie

[Onno Benschop]

Hey, after the spate of postings about changing the desktop under gnome,
I decided that using this as my desktop would be cool: (note, this file
will be deleted ~ 36 hours from now :-)

	http://www.bom.gov.au/gms/IDE00005.200407210030.gif

And wrote a script that puts all the files into a weather directory.
Using the time honoured ImageMagick software I've been playing with
making a time-lapse movie of this.

The most obvious conversion is:
	convert *gif weather.mpg

This works fine, but it starts dying at frame 100 or so with all manner
of buffer delay blah errors and the resulting movie is very blocky for
those frames.

The next conversion I tried is:
	convert *gif weather.m2v

This works great and plays fine in xine - and sometimes even in mplayer.

However, it fills up RAM with all the images, and causes a phenomenal
system load *before* it actually starts doing anything with the encoder.
The system is completely unusable during the conversion.

I've spent some time with google looking for ways to append a single
frame to a movie with no success.

So, how can I make a movie of all these frames and how do I do it in
such a way that I can append the latest frame to the movie every hour?

PS. I know that a package motion appends frames, but I've no idea how it
does it and I don't really have the inclination to actually write any
application to do this, seeing as I've got about 40 others of a higher
priority :-)

Any suggestions?
