Hi,

I am trying to make a patch which combines a (potentially quite large) number of video inputs into one matrix. I want to be able to control the opacity of each video. Say there were 5 videos I might like them to all show at 20% opacity, or I might like one to show at 40% and the rest and 15% and so on.

The number of videos may change, so I would like the patch to adapt to this circumstance.

The ways I’ve thought about doing this is with straight jitter and probably javascript or using opengl and slabs (and probably still javascript).

I would really appreciate some feedback on a good approach to aim for because I haven’t done a lot of work with opengl, shaders or javascript within max. I don’t want to dive into shaders right now if it’s not necessary for my project.

Jitter tutorial 43 (a slab of your very own) is pretty much what I want, but I want to make the number of videos variable.

Thanks in advance!
