Firstly I couldn’t vouch for the GPU in the mac mini, I have never used an internal GPU for compositing or 3D.
I am now moving away from combustion in favour of Nuke (very much like shake).
Combustion is a 2D compositor, whilst it has some nice features like the discreet keyer it’s way of working in layers AND the outdated schematic view is rather sluggish.
If you are new to compositing Shake is an excellent start, I wish I had started with node based compositing a few years ago rather than Combustion. Working with nodes instantly gives you a better udnerstanding of the maths that goes into colour.


Shame on eyeonine for getting my hopes up!
