Hi,
I am pasting a script below which I've used to make movies with ANUGA viewer [under linux]. It relies on imageMajik's "convert" program to work.
At the top are comments which explain how to make the directory of images with anuga-viewer -- in the original question, I think this was not being done correctly.
Apologies for any automated reformatting of the script which my email editor might do.
The key steps are:
1) Use anuga-viewer to make a directory of images.
2) The script below will stitch them together, get rid of repeated images, etc.
Beware that you still might need to manually delete the first image that anuga-viewer produces if it doesn't look right.
Cheers,
Gareth.

Script to automate steps in making an anuga-viewer based movie
This assumes you have made a directory of jpg images with anuga-viewer
It also assumes you are running ANUGA from linux, and the 'convert' program is
installed [part of ImageMajik]
To produce the images:
1) Start anuga-viewer, and get the view oriented how you would like for the movie
2) Press 1 to start recording, space to start the animation, then press 1 to
finish recording, and 3 to save the movie to 'movie.swm'
3) Close anuga-viewer
4) Make a directory with images of the movie, with:
> anuga-viewer -movie MYMOVIEDIR movie.swm
Let it run until finished.
5) Look at the images. You might want to delete the first one (seems to have a
blue background irrespective of the actual value of trace set in anuga-viewer).
Don't worry about repeats -- this script will remove them.
Finally you can run the current script, setting the input parameters as appropriate
