On OSX the pix_film/movie object defaults to YUV. Send a 'colorspace RGBA'
message to the object before loading the clip if you need the alpha from the
clip. pix_image uses RGBA by default. If you have problems with PNG the
try uncompressed or TIFF.
i'm trying to port a former jitter patch to pd/gem
i have problems getting overlayed images to display
properly. i have four rectangles fed by pix_movie,
then i need to fade in and out a rendered text image.
i tried using pix_image -> pix_texture and [alpha 1].
the images are .png with transparent portions. i once
got it to display correctly, but now if i open the
patch, the videos all show up with wrong colours:
