      thanks for your help
About compositing 3D
I can't use pix_snap because my GLoutput is in 1024 768
and I think that the computer will cry to pix_snap and pix_resize
continuously
About the problem with the pix_mix object
at the begining, I put a pix_flip object before the right inlet
with a result strange : picture is alternativelly flipped up and down
the solution that I found is by the pix_film source object :
before, I used a metro to changing number of image
(to get the possibility to change the rate)
in fact, if I replace this metro by a derivating bang from the gemhead of the
pix_film, the path pix_flip>pix_mix is working well
You can see the exemple patch next
the last problem is that, if I put a rate < 1 (in the |pd lecteur_video_boucle|)
the hysteric flip is recoming
but it's now very better!!!!
