thanks IOhannes for being patient.
well, i am still a bit unsure. do you mean that the stuff i described
below canNOT be recorded at all within puredata? i.e. do i have to
make a recording using the ouput of the graphic card?
i am now trying to record a single rectangle moving over the Gem window.
do i have to use pix_snap synchronized with pix_record to take a
sequence of snapshots? (i only get a green video output).

i agree with you, my description is not crystal clear.
imagine that there is a video in the background (fullscreen).
progressively some small recatngular parts of the video are transformed
(for example gets darker) and move - in order to do that i apply
another
gem layer on top of the video layer and insert several rectangles
objects with alpha channel.
thanks.
what you describe canNOT be recorded directly with [pix_record] (you
already know that).
[pix_record] will _only_ record pixes. (e.g. you have to transform
your
"rectangles" into pix-domain; just using [rectangle] won't do)
ok, how do one make this kind of transformation?
[pix_snap] transforms the rendering buffer (what has been rendered so
far in the render-cycle!) into a pix-buffer.
e.g.
[pix_video]
|
[pix_gain]
|
[pix_record]
|
[pix_invert]
will record a video with [pix_gain] applied, but [pix_invert] is NOT
applied.
ok, i think i got this one but what about pix_mix?
[pix_mix] is harder to draw in ascii. apart from that you shoud insert
it instead of [pix_gain] to have an effect.

It would be nice if pix_snap worked on winslows
