Currently, the settings are saved at a global level and automatically save between Maya sessions. I plan on making the settings save during inside sessions but reset between sessions. I think I'd like to make settings connect to Maya scenes, but I'll have to do more research to see if that's possible. At the moment reseting settings between sessions is what I'm working towards.
Still needs some work, .mov is giving me issues with ProRes, DNxHD, and DNxHR, and some settings currently don't do anything. But it works for simple playblasts!!!
