This operator does needed changes to - 3D viewport - Scene settings - World settings - Compositor - Scene objects in a way scene becomes ready to be composited into footage. Known issue: preview doesn't work "out-of-box" after running this script, selecting View node and hitting Tab helps. Not sure it can be solved in nicer way at this moment.
