Green screen

green screen is hard, if you have great lighting, on the subject and the screen and a good camera (442- better colour reproduction) you can start to work. I would seriously look at renting hardware for this. The blackmagic ATEM switcher 2me has a pretty good kery inside it, it is a cheap piece of kit- under 2k and rental therefore is also cheap. You can run an SDI camera into it and feed your background into another input and you have your composite without touching anything in Izzy- leaving your machine free for making everything work. The other great advantage is that you will have only 1 frame latency if you output the image from the mixer, if you want to put it back into your computer for mapping you only have the roundtrip delay no processing.
The other solution to look at is TSPShttp://www.tsps.cc/It might help, with proper lighting you can use background subtraction and send the mask over syhpon. -
So maybe this could be a new thread: to find FFGLs for the effects we used till now. For example I cant find a simple motion blur, I only find blur.
There are others that would be also great: Luminance Key, HSL adjust, ... -

@primaldivine Is there a motion blur in that list for mac? I cant find any plugins on the petewarden site, because there is a plugin listed "Petedirectionalblur" on your link

an interesting framework on github for iOS gpu effects... its not FFGL.. but related I suppose.

Are you familiar with the Interactive Shader Format developed and made open source by the VDMX guys?[http://vdmx.vidvox.net/blog/isf](http://vdmx.vidvox.net/blog/isf)It would allow potential hundreds of GLSL shaders from [Shader Toy](https://www.shadertoy.com) and [GLSL Sandbox](http://glslsandbox.com) to be made accessible in Isadora. The Shader code needs to be modified with a header to publish the inputs but it appears relatively easy. While not as powerful as FFGL there does appear much more community activity in developing GLSL shaders which we could all benefit from.The downside is that it is Mac only ATM but I wondered if it was something that would be of interest to Isadora users? -
This was discussed at the meetup in Berlin wasn't it?
I can't remember the outcome but I guess new features aren't top of the list at the moment.+1 from me though.Would it be possible to write a FFGL plugin which can dynamically load isf files? -
@Unfenswinger
thanks for the link. WIll look into this next week. -

For Quartz Composer ninjas here's a nice tutorial how to setup GLSL shaders in QC,
