i'm really new to max/msp/jitter, so any help would be great!

i am using a proximity sensor connected to arduino, which with distance, will effect the pace and transparency of the 3 videos and 3 sounds.

If someone could direct me to a tutorials or example code on how to layer videos and mess with the transparency, that would be most helpful!

no better place to start out than the jitter tutorials.

posting a patch showing your concept will also get you much more useful advice.

second that about the tutorials, as well as reading the docs about jitter in general and GL in particular. You might try jit.gl.videoplane, look in the help file, and get a movie playing onto it. Then you can change the alpha level (the last number of the color message) so you can see others behind it. blend_enable needs to be on, and probably you want the first three color #s to be 1. 1. 1. (so it's white and doesn't affect the original video with colorization, unless you want that).

so the relevant data from your Arduino would affect the "color 1. 1. 1. $1" message to jit.gl.videoplane, in that the $1 would range from 0. to 1. (transparent to opaque). Look at the [scale] object too, if your data in needs tweaking to an appropriate range, which it likely will.

for the sounds, change the pace with a speed $1 command (for sfplay~) or a changing sig~ value (if using groove~ and buffer~). Take some time to look into these and experiment. I always use buffer~ and groove~ with rate-changing. If you want to keep pitch the same when changing speed, that's trickier, but the relevant object is gizmo~. Look into this after you understand how buffer~ and groove~ work, gizmo~ is more to digest and set up. But if you just want to speed up and slow down, that's easy with groove~.

please help! overlaying 3 video clips?
