hello,
Gem is mostly design to work on the GPU, and not on the CPU.
GPU have hundreds of core, they are faster than CPU for image manipulations.
pix_add come from the 20th century and should now be avoid since it use cpu not
gpu ;-)
in order to make a fade transition between 2 videos, you can use transparency
on one video.
add a [alpha] object after Gemhead, and send number between 0 and 1 in the last
inlet of the colorRGB object to make the video appear / disapear.
cheers

Hello,
So, looking at the help file for [pd~], it seems to be primarily for
audio. How can I use multiple cores to work purely with GEM?
I am trying to have a simple transition between video clips, but if I
have two instances of pix_film and then connect them to pix_add, the CPU-ussage
skyrockets well above 100... is there a more efficient object for blending two
video clips?
Best regards,
Stephan

Pd will only use one core, and one core for the GUI. There are ways to
distribute the load over several cores, e.g. [pd~] or use several
instances of Pd that communicate with each others:
