Personal-cinema architect John Bishop talks about movie aspect ratios and how to accurately reproduce them. Topics include the aspect ratios of different movies through history, how some movies (such as Dunkirk and The Dark Knight) use more than one aspect ratio, his experience seeing Dunkirk in several venues with different projection setups, optical-anamorphic versus electronic aspect-ratio control, how electronic scaling affects resolution and contrast, the constant image-height approach to multi-aspect-ratio setups, answers to chat-room questions, and more.
