AVS-Mixer is a program inspired my @microdee which will take any 4 input windows you specify and mix them in a tree-like fashion - (1+2)+(3+4). Everything in realtime of course. I use it to mix a couple of Winamp’s AVS renderers live in clubs for some non-video VJing. (Some nodes from the AddonPack are needed - tell me if any more are missing…)
So - I have made a git repository, for anyone (@r4dian?) who is interested in downloading or even contributing to (contact me) this beta-thingie…
I promise, the patches are and will continue to be nicely laid-out and (mostly) well-documented :)
Also http://visbot.net has some pointers - not to mention all the hottest presets! :D
Cockos AVS is also not really the best, albeit it’s newer, but it can not run all presets (especially not some with more complex coding). I would try vis_avs-2.81b or vis_avs-2.81d from here.
(And yes, I should really do a readme over on github…)
