Proceed as in the case of the 2D-animation. But usually come simpler or shoot 25p (progressive scan cameras are far more common than 50p), or treated with interlaced video filters 'de-interlace', which, however, reduces vertical sharpness twice. Transfer video: video compression algorithms are very sensitive to a large number of small elements in the image and the horizontal notch edges of moving objects have a thickness of just one line. The screen is filled with small leaves, waving in the wind – a nightmare for mpeg. Approx. Auth. Frame format.

Or aspect ratio – for the plasma is 9h16. When viewing a TV broadcast, 3×4 format, the edges are there black bars. Due to a phenomenon known to time as a CRT phosphor degradation, it does not always go unnoticed. Especially in the first-generation model. Phosphor in these areas remained more 'fresh' in long-term view images 3×4. If you then turn on widescreen image, you may have noticed a higher brightness at the edges of the image. Must either stretch the image horizontally, or cut the band above and below.

In some models, you can change the color unused areas when viewing 3×4 format from black to gray. Advertising tricks. The brightness of the panel. First, it is lower than the brightness of the TV – in the finished product before the panel is a light filter. Secondly, the brightness point, in order to protect the panels, decreases with increasing background area. A single point of light is brighter when she lit one (or in a small area) and a somewhat less bright, white lights if the entire panel. Contrast. Its value depends on how brightly lit room, in short there is a panel. Contrast in a completely dark room and a brightly lit can vary by tens of times. How can that be? Carefully viewed in the store model of interest – because we ultimately are interested in image quality, but not the values of technical parameters. Beaten and unmanaged pixels on the 'plasma' is not allowed, what would we have spoken to shop. Drops of tar. Plasma TVs consume considerably more energy than LCD, as a result of which model is seldom complete without cooling fans. In the store or even at home during the day extra sounds at first and can not notice and then wonder when you watch a movie late at night. Someone did not notice a little boom, and someone annoys even subtle sound flowing air heaters. 'Burnout' phosphor. In recent models TV is not so important as in the first place, the life of the panel is 60,000 hours or more (while the brightness of the phosphor will not go down twice from the original). Nevertheless, there remains the problem of uneven brightness reduction across the screen. Manufacturers are struggling with this in different ways, however, it is difficult to recommend a plasma to display static images. The budget model should pay attention to the graininess – should carefully examine the picture on the screen at this distance, with which you want to watch TV at home. If the grain from this distance is too obvious, it is best to choose a smaller diagonal, or TV higher class – for example, HD-Ready model. The advantages of plasma televisions, of course, more than disadvantages. When choosing the right long it will please the consumer with its bright, juicy picture. * Standard Definition TV (Standard Definition) – 720×576 or 720×480 and higher, 'extended' (Extended Definition) – 853h480.
