layering JPGs

hello, I want to layer black&white JPGs in a live performance.

is there a better way than [jit.op @op *] ?

my MAC, 2.7. Core i7 needs some time for this layering process – it is becoming slow.

does anyone know a tip ?

Are you using JPGs that are much bigger than the screen reolsution? If so, you can resize them in a photo editor for better performance.

Have you considered using and one or more composite shaders? This will offload the processing to your video card’s GPU. See the example composite.shaders-help.maxpat in Cycling ’74Max 5.0examplesjitter-examplesrender
