Maybe not-so-simple slideshow
I am working on an installation that involves calling still images up onto a screen for a set amount of time, and then fading out. The images will be called up by pressing individual buttons on a 128 monome array. The photos will layer one on top of the other, and decay over a set interval.
I’ve done the best I can with what I know, but seem to be having problems getting the images to overlap—they seem to flicker when layered on top of one another. I don’t know if it’s due to the times set on my metros or what, but I’d welcome any suggestions.
Right now in this demo the photos are triggered by “a” and “s” on the keyboard.
I am looking to use a selection of over 128 images for this project, and control 3 projectors for a total screen space of 3840×720 using a triplehead2go. I had initially thought this would be simple, but am I wrong?

hi,
use one [qmetro] for both jit.qt.movie objects.
pass them both to [jit.xfade] for fading, the way you set it up now they “compete” for the same window, without playing nice with each other.
note to remember: jit.xfade expect a bang on the left inlet to output, so even if you don’t send a new matrix you should bang it with every frame.
look at andrew b. “video processor” line of tutorial for some next level gpu based xfading.
