Screencast: Routing iTunes’ Visualizer into ProPresenter

Readers of this blog will recall my fascination with Robert Hodgin’s Magnetosphere visualizer. He’s a true genius when it comes to tastefully visualizing music (so few visualizers actually look good). The story of its purchase by Apple for iTunes was broken right here on this blog last year.

As part of my role at the Palau Association, we needed to find some ways to webcast content generated on a Mac. I found the excellent, free and deep CamTwist to excel at taking the output from one region of the screen or application and routing it into “fake webcam” (essentially a QuickTime component that acts like a DV/Firewire source). Heyyy… ProPresenter will take a Firewire DV input! Let’s make some music, then…

Here’s this concept put into practical use by the geniuses at WorshipVJ. If this stuff excites you, then consider joining the WorshipVJ Facebook group.

I still haven’t found the Holy Grail of being able visualize live audio with iTunes in a music setting. In a future post, I’d like to look at some of the practical problems that this approach creates (namely doing all that crazyness on one machine) and explore some alternatives. Got any other ideas?

Great post. Got here from Proctors page.

Multi machines is a good discussion… let an artist be just that and a ‘trainee’ focus on the words and be observant while you are teaching them the ropes, if you will.

Looking forward to more !.

I am currently working on this exact thing.  Using some various code through quartz composer, I am able to get some good effects.  Using Wow Lab’s Bugaboo quartz file as a reference, I was able to create a great particle system that reacts to live music.

take a look at G-Force. Its a live visualizer that works from various sources. Have a look and see if there is any open source (maybe, but worth a shot) from them. I am looking into it for PC purposes wink and making a live feed to Arkaos as a mixer.

I purchased a few products from SoundSource (WhiteCap, G-Force, SoftSkies), but all of them feel a little too techy.  They may have a good use for Worship, but they aren’t a default background for our services.  From everything I can tell via a cursory overview, there is no open source code in these products.

uhhh…. why am i just now seeing this?! you need to tweet or text me when you do awesome things like this!
i’ll tweet this when people wake up… it’s 4am central. sleep fail.
