Dear all,

sorry for bringing this topic up again. I want to include a view movies in a
PowerPoint-presentation and have a view practical questions. The route I am
following at the moment is:

Bobscript --> PovRay --> Mediaconvert (avi-files) --> PowerPoint.


First, I run into the following problem: While my little animation (ribbons
rotating 360 degrees around y) plays fine in Mediaplayer, PowerPoint (in
Windows2000) seems to take the liberty to change resolution as soon as it
starts playing (to the worse, of course). Can I stop this? Could this have
to do with some kind of stupid screen-resolution setting as a "clever"
optimisation for quicker playing?

Second and more specific: How big should my rotation steps be (using 3
degrees at the moment, wonder if I could go coarser)? What should my
resolution be (use 600*600 at the moment with anti-aliasing etc, wonder if I
should switch all that of if I can't get PowerPoint to behave itself)? How
many frames per second should I do (18 or 25 like on my dad's old Super-8
film camera or is less ok?)? I want something that rotates quite slowly not
to make people in the audience nervous...

I have also tried animated gifs but they look quite sh.... in PowerPoint,
again losing resolution.


Thanks for any help,





Wulf
