[Sea-mat] new to group, movie question

[Richard Signell]

Lynn,

I still use the "anim_frame.m" and "anim_make.m" m-files that
you can get on the sea-mat site:

http://sea-mat.whoi.edu/RPSstuff-html/anim_make.html


This uses screen capture so what-you-see-is-what-you-get (doesn't
use the print function), saves the images as PCX and then converts
them into a .FLC animation using "ppmtofli".  The flc format is 
still a good format for many applications (better than mpeg for
most of the movies I make) and has viewers for all
platforms.  See:

http://woodshole.er.usgs.gov/operations/modeling/flc.html

Also if you need to convert FLC to AVI, say for use in 
MS Powerpoint, you can use shareware tools
such as "videomach" from http://www.gromada.com (use the RLE
codec for compression, as it is similar to FLC).

The only drawback with the "capture" method is that you can't
obscure the figure window while you are making the movie, which
can take a long time if you have 800 frames.  So you can do it
overnight, or you can use the trick that I use:  I start a 
VNC server on my machine, connect to the server using VNC viewer,
start Matlab in the VNC viewer window, and then run my movie maker
in this window.  Since it's a virtual server, you don't have
to worry about obscuring the window.  Maybe there is a smarter way
(if someone knows, please tell me), but this works.
