所谓2:2帧复制是把每秒24帧电影胶片信号变换到每秒50场视频信号,它由每秒25帧电影胶片信号复制完成。其处理过程与把每秒30帧电影胶片信号变换到每秒60场视频信号相似。其结果是非常简单地把一帧电影胶片图形复制为一个奇数场和一个偶数场视频信号。
The so-called 2: 2 frame copy is to convert 24 frames per second to 50 fields per second video signal, which is copied by 25 frames per second film signal. The process is similar to converting 30 frames per second to film video at 60 fields per second. The result is a very simple way of copying a frame of motion picture film into an odd field and an even field video signal.
