[PyMOL] Movie making questions

[Yuri <yur...@uf...>]

Dear Users,
I was putting together some movies using pymol and I have some 
questions.
First, how can I gradually make a surface go from solid to transparent? 
Currently what I see is, in scene 1 I have it solid (0% transp.) 
surface. Then after I show some ligands and aa side chains in scene 2, I 
try to get the surface to look transparent (60%) in scene 3.
However when I reinterpolate and play the movie every surface will be 
60%, the last setting I entered.
Second, how can I make an object (ligand shown as stciks) rotate or 
flip? I can make it move using "translate" but this happens in a linear 
fashion.
Lastly, I like to save movies as pngs and later create the movie. How 
can I change the output frame size, e.g. 1024x1024?

Thank you so much for your time,
