After dealing with my dual core 1.60 Ghz laptop for rendering this, finally I present you with my latest vfx test with Blender 2.63.
I use GIMP for cleaning some mess in premultiply plate, the entire workflow only use FOSS. I enjoy it very much.
You can download the original footage from here http://www.hollywoodcamerawork.us/greenscreenplates.html. What I use on this project was Main SD plate only and doing tracking & compositing from scratch.
I welcome with any feedback, thanks for watching.
