Below link are the forum to a plugin that I found useful for Adobe Premiere pro CS6 and Adobe Media Encoder CS6. It exports 4 times faster than normal export mode.

I've done a few tests and every form of editing (Color correction, Dynamic link to AE, stacking videos etc) in time line and try to export using the plugin. An error will prompt however when I choose ignore, it will still render. Anyone tried the plugin before?
