from other colors.
interlacing Flickering or artefacts caused by the way video
signals are broadcast. (Each frame of video is
made up of a number of lines. When video
frames are broadcast, the odd lines of the
screen display are illuminated first, then the
even lines. This causes the interlacing problem,
which is most evident when the video contains
motion.)
key frame A key frame is defined as a frame in a video
sequence that does not require information
from a previous frame for decompression.
More key frames yield better video quality but
require greater amounts of disk space.
