I'm new to the RT performance world so apologies if this is old news.

It was discussed, and is definitely of interest.

I believe its on the roadmap.

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?

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?

There are others that would be also great: Luminance Key, HSL adjust, ...

The other solution to look at is TSPS

It might help, with proper lighting you can use background subtraction and send the mask over syhpon.

I've been using the plugin version of Conduit for years in Motion and it has proven it's worth on many occasions when a nodal approach to compositing has been required.

For what it's worth: none of the CPU based plugins are going to perform well with HD. In the old days of 640x480, they were quite usable. But for 1920x1080, they just can't handle the bandwidth. That's why 2.0 + FFGL is the path everyone must adopt for the future.

Best,

Windows only though and the sdk is still in Beta at the moment.

You can use what ever tool you want to do the key - what matters is the quality of your source image.

Great summary of your workshop Jacques.

Klaus K.

I have made some experience with students during workshop, here are my conclusions:

— like every green screen, quality of light and camera are priority, separate lighting for background, key light, backlight, preferably 4.2.2 camera with real video in, like blackmagic.

— Isadora chromakey works but is far away from real key software and hardware

— there is a time delay, so no lipsync

— it's really computer consuming, so dont hope to play and mix many other clips in realtime.

But nothing better than your proper test with your hardware and hopes…

All the best,

Jacques Hoepffner
