Deinterlacing also is needed to make proper use of additional digital processing, in particular image stabilization and frame-rate conversion. Deinterlacing, if done well, solves this problem. Today's digital monitors avoid the venetian-blind effect, but worsen the jaggies, because these monitors display the two interlaced fields of a video frame at the same time. Interlacing does produce some visible artifacts, particularly 'combing' or 'jaggies' when there is rapid motion, a 'venetian-blind' effect when motion upward or downward in the image harmonizes with the field rate, and 'interlacing twitter' when an image contains sharp, computer-generated horizontal edges. The complete interlaced image is displayed only 25 or 30 times per second, reducing the bandwidth necessary to transmit the signal - but the doubled field rate, 50 or 60 per second, is high enough to eliminate visible flicker. Note the jaggy, doubled image in the foreground where the view is expanding as the bicycle moves forward, and the jaggy image of a tree trunks in the background due to panning. The image below is one frame from NTSC 640 x 480 interlaced video of a bicycle ride. Why interlace? Interlacing is a simple form of data reduction which takes advantage of limitations of human eyesight A detailed explanation of interlacing may be found on Wikipedia. The first field displays the odd-numbered scan lines of video, the second one, the even-numbered lines. Each video frame is displayed in two passes, called 'fields', one after the other. Video recorded at the old NTSC and PAL broadcast standards, as well as 1080-line broadcast digital video as of 2019, is interlaced - that is, a complete video image is produced by two consecutive scans (fields).
