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 ...
Two consecutive fields compose a full frame. If an interlaced video has a frame rate of 30 frames per second the field rate is 60 fields per second, though both part of interlaced video, frames per second and fields per second are separate numbers. A broadcast television camera at the Pavek Museum in Minnesota.
This results in a sharper and more stable picture, especially in fast-moving scenes. On the other hand, 1080i uses an interlaced method. The two fields that make up a frame are captured at slightly different times, leading to a misalignment in fast-moving parts of the image.
Deinterlacing is the process of converting interlaced video into a non-interlaced or progressive form. Interlaced video signals are commonly found in analog television, VHS, Laserdisc, digital television when in the 1080i format, some DVD titles, and a smaller number of Blu-ray discs.
Shot on digital video in interlaced 60 fps, with some scenes shot on 35 mm movie film in 24 fps. Shown in cinemas in 24 fps and in interlaced 60 fps with 24 fps segments on DVD and Blu-ray. 1999 The Blair Witch Project: Daniel Myrick, Eduardo Sanchez: English Shot on Hi8 in interlaced 60 fps, with some scenes shot on 16 mm film in 24 fps.

In the United States and other countries where television uses the 59.94 Hz vertical scanning frequency, video is broadcast at 29.97 frame/s. For the film's motion to be accurately rendered on the video signal, a telecine must use a technique called the 2:3 pull down (or a variant called 3:2 pull down) to convert from 24 to 29.97 frame/s.
Confusingly, interlaced formats are customarily stated at 1/2 their image rate, 29.97/25 FPS, and double their image height, but these statements are purely custom; in each format, 60 images per second are produced. A resolution of 1080i produces 59.94 or 50 1920×540 images, each squashed to half-height in the photographic process and ...
The quadruplex format employs segmented recording; each transversely recorded video track on a 2-inch quad videotape holds one-sixteenth (NTSC) or one-twentieth (PAL) [6] of a field of interlaced video. (For NTSC systems, the math suggests 15 transverse head passes, each consisting of 16 lines of video, are required to complete one field.)
