Interlacing
23 Dec, 2019 by
Interlaced video is video captured at 60 pictures (known as fields) per second, of which every 2 consecutive fields (at half height) are then combined into 1 frame. Interlacing was developed many years ago for the analog TV world and is still used widely today. It provides good results when viewing motion in standard TV pictures, although there is always some degree of distortion in the image. To view interlaced video on e.g. a computer monitor, the video must first be de interlaced, to produce progressive video, which consists of complete images, one after the other, at 30 frames per second. See also Progressive scan.
