Open Source Compositing

Blender is well known as a free, open source 3d modelling and animation application that can produce results to rival commercial products such as Maya, Lightwave or 3DS Max. However it also recently had a node based compositing system added. Blender is open source so is not necessarily the most user friendly piece of software to learn and documentation is often literally years behind the actual product.

However this will hopefully be address in the future, and it would be a great addition for low budget film makers who want to do keying and matte work, even if they don't have any need for Blender's 3d creation tools.

Hopefully at some point I'll get a chance to try the compositing side of the app to see what it offers us no-budget-blue-screeners.
