The way I tried to address the export issue is to maximize the speed and effectiveness of the Adobe Mercury Playback Engine. For me this was buying and HP Z820 system with the fastest processors,a fast GPU, 64GB of ram and fast media IO with the Dulce DQg2 raid arry. Im not sure there is anything else that can be done. Except avoid any slow plugins and 4K projects 😀
