Autodesk has the pre-release trial version of the new Smoke for Mac 2013 available for free until December. At that time the software will be officially released, for purchase.
Smoke greatly streamlines your workflow by having all the tools you need in one package. It has a standard timeline editor, but allows you to jump into any number of deeper tools such as advanced color correction, a very powerful tracker, and a 3D node-based compositor (among others). And it’s all right there. Make your corrections, and jump back into your timeline to continue working.
