I have used this way.
I would advice to make gif animation in addition.
The problem is that not every windows pc can play mpg files.
Gif animation can be shown in every web browser.
In yorick the program may look as (similar in fortran):
for(k=1; k <= mm; k++)
{
kk=(k-1);
//plsdev, "tk";
plsdev, "png"; plsfile, pr1(k)+"ee.png";
plspage,600,500,600,500,1,1;
plscolbg,255,255,255;
plinit;
plssub,3,1;
.....and etc.
}
Then convert -scale 708x608 -delay 100 1ee.png 2ee.png 3ee.png \
4ee.png 5ee.png 6ee.png \
7ee.png 8ee.png 9ee.png \
10ee.png 11ee.png 12ee.png \
13ee.png 14ee.png 15ee.png \
16ee.png 17ee.png 18ee.png \
19ee.png 20ee.png 21ee.png 22ee.png 23ee.png \
24ee.png 25ee.png 26ee.png 27ee.png 28ee.png \
29ee.png 30ee.png 31ee.png -loop 0 dyne.gif
The result can be found at
http://iszf.irk.ru/~pip/dyn.gif. This is an animation for solar dynamo model
The gif can be transformed to mpeg and avi. You have to know the right codecs
(those from pc where you will show the movie) .
