What is interlaced video?

Interlaced video is a technique for doubling the perceived frame rate of a video display without consuming extra bandwidth. The interlaced signal contains two fields of a video frame captured at two different times.

Interlacing problems

Interlaced video is designed to be captured, stored, transmitted, and displayed in the same interlaced format. Because each interlaced video frame is two fields captured at different moments in time, interlaced video frames can exhibit motion artifacts known as interlacing effects, or combing, if recorded objects move fast enough to be in different positions when each individual field is captured. These artifacts may be more visible when interlaced video is displayed at a slower speed than it was captured, or in still frames.

What is progressive scan?

Progressive scan (alternatively referred to as noninterlaced scanning) is a way of displaying, storing and transmitting moving images in which all the lines of each frame are drawn in sequence. And the main advantage with progressive scan is that motition appears smoother and more realistic. Frames have no interlace artifacts and can be captured for use as still photos.

Why need to deinterlace interlaced video into progressive form?

Most cathode ray tube computer monitors, all LCD computer monitors and most HDTVs only work in deinterlace mode, because they are fixed-resolution displays and only support progressive scan. When you display an interlaced video on a progressive scan monitors, which scan lines of an image consecutively, the artifacts will become noticeable. To remove those annyoing artifacts, it would be much ideal for you to convert the interlace video into progressive form.

Most modern displays, such as LCD, DLP and plasma displays, only work in deinterlace mode, because they are fixed-resolution displays and only support progressive scan. In order to display interlaced signal on such displays, the two interlaced fields must be combined into one progressive frame with a deinterlacing process. To deinterlace the video, there are 3 free, simple and effective methods to remove the saw tooth type edge distortion below.
