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.
