it does !

thanks a lot for your explanation,
your method also works with the chained shaders !

even though my ambition was to use one gemhead for everything, i see 
that your preferred solution with a second gemhead is much better and 
also looks more logical to me.



one last question:

wouldn't the [pix_buf] method be more cpu intensive ?

because it says in the help file:

"[pix_buf] is only effective if it is storing a static image. If you are 
continually modifying the buffered pix, then pix_buf is going to be 
spending a lot of time copying pixels."

... which i think i do when i'm feeding a film into it, isn't it ?
yet i didn't notice any raised cpu power with [pix_buf] even though i 
used a 1280x720 film.



best
