In my day, my young ’uns, faster frame rates than the usual 23.97, 24, 25 and 29.97 frame rates were only useful if you wanted smooth slow motion. With Peter Jackson boldly using 48 frames per second for The Hobbit, the idea that they could be used as a playback option has a good chance of taking hold. The effect is the smoother motion that TV viewers associate with news shows, talk shows, daytime soaps and certain multi-camera sitcoms. To the editor, that’s known as interlaced, and it’s a pain and a remnant of antiquated broadcast systems. Can we now consign it to the cutting room floor of history?
