interlaced vs. progressive image: ITALIAN upload.wikimedia.org interlaced video is designed to be captured, recorded, transmitted and displayed always interlaced. The main limitation of the technique of interlacing is creating visible artifacts during rapid movements, particularly in those subjects that move fast enough to be in two different positions in the two fields of the same frame. Artifacts are easily visible during playback of still images or at lower speeds than rated. Since computer monitors are progressive in nature, an interlaced signal will appear on them with the presence of artifacts. In particular, the widespread use of software forinstallation often requires the use of special hardware to display interlaced video correctly. An external monitor is very common and recommended practice. To minimize artifacts visible on a progressive scan monitor, a technique known as deinterlacing. The resulting video is often of lower resolution, especially in areas with moving objects. Plasma TVs or LCD and integrated deinterlacing systems are often used to display interlaced signals. Another problem caused by interlacing is the twitter effect, visible when the video contains vertical detail near the ...
