Problems Caused By Interlacing
Interlaced video is designed to be captured, transmitted, or stored, and displayed in the same interlaced format. Because each frame of interlaced video is composed of two fields that are captured at different moments in time, interlaced video frames will exhibit motion artifacts known as "interlacing effects", or "combing", if the recorded objects are moving 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 when still frames are presented.

Famous quotes containing the words problems and/or caused:
“The problems of the world, AIDS, cancer, nuclear war, pollution, are, finally, no more solvable than the problem of a tree which has borne fruit: the apples are overripe and they are falling—what can be done?... Nothing can be done, and nothing needs to be done. Something is being done—the organism is preparing to rest.”
—David Mamet (b. 1947)
“Every life and every childhood is filled with frustrations; we cannot imagine it otherwise, for even the best mother cannot satisfy all her child’s wishes and needs. It is not the suffering caused by frustration, however, that leads to emotional illness, but rather the fact that the child is forbidden by the parents to experience and articulate this suffering, the pain felt at being wounded.”
—Alice Miller (20th century)
