同样是23.976fps片源,看不出24Hz(72、96、120)和60Hz播放区别的可以去看眼科。作者: Edison 时间: 2010-9-11 13:19
Without FRC, 24Hz rendered film is normally displayed on progressive systems by duplicating frames in a 3,2,3,2,3,2... pattern (with the average repetition of 2.5 as expected). This output pattern itself has a repetition rate of the greatest common divisor ({mod}) of 60 and 24, i.e. {mod}(60,24) = 12Hz. Unfortunately, this frequency is visually annoying, particularly with fast camera pans. You may yourself have become aware of juddering motion while watching movies. The effect can be reduced by using a display that refreshes at 120 FPS (5:1), as then the motion repetition is {mod}(24,120) = 24Hz, not 12Hz.作者: 空壳 时间: 2010-9-11 23:36 回复 2#loulan
