These are google images that I used to joined a fake movie trailer project that I am working.
The images below are from the Natron script project. I must say that I love Natron. I know it still has a way to go for what other compositors need to work with on a daily basis, but 95% of the work that I do is 2D and Natron comes through every time. I think more keying node algorithms would be nice. The Chromakey, PIK/PIK Color, and the HSVTool used as a keyer are powerful in their own right. I think the HSVTool could be the most powerful keyer of them all if you use it right. See my tutorial on it at https://colorgrade13.wordpress.com/2015/05/07/natron-digital-compositor-hsvtool-node-tutorial/.
Here is just a test bootleg render for the preconception stages.
I will be coming back with other results for this project.
