Generally speaking, interlacing is a very useful technique
developed by people with the intention of capturing, storing, transmitting and
displaying the interlaced video in the exactly same interlaced format. Its wide
application in today’s scienece and technology field proves that interlacing is
really very helpful and thus widely accepted by people. As a matter of fact,
each interlaced video frame is made up of two fields which are captured at two
different times. As a result, the interlaced video frame is likely to exhibit
motion artifacts. Those artifacts, known as interlaced effects, or combing,
will appear when the recorded object moves fast enough to be in different
positions when each individual field is captured. If the interlaced video is
displayed at a slower speed than it was captured or displayed in still frames,
then these artifacts will be more visible. Therefore, people are supposed to
try their best to avoid these motion artifacts in order to get the most
satisfactory progressive frames. Only under such circumstance can people enjoy
the video of the best quality.
Fortunately, there are some both simple and useful methods which
can help users to produce satisfactory progressive frames from the interlaced
image. For instance, users can make use of the function of doubling the lines
of one field and omitting the other, namely, halving vertical resolution, or
anti-aliasing the image in the vertical axis, which will be of great use for
them to hide some of the interlaced effects or combing. Sometimes, these
methods can help users produce progressive frames of more satisfactory quality.
Therefore, users are supposed to make the fullest possible use of these
functions to help themselves produce better and more satisfactory progressive
frames. With these functions and adjustments, people will have the opportunity
to enjoy the video of the best possible quality.
