hello list,

I am using GEM on WindowsXP. I would like to mix videos with 
transparency (that is, with alpha channel). But I cann't find a codec 
that supports that. Do you know anyone?

A way to solve the problem would be to show a image sequence (PNG files 
with 32 bit color). But, for that, I would have to transform a number 
into a string, and concatenate it with a string (for exemple, "frame" + 
number + ".png"). Is it possible to make that?

thanks a lot,
