Most cue marks appear as either a black circle (if the physical hole is punched out on the negative used to make the projection print of the film), or a white circle (if the mark is made by punching a hole or scraping the emulsion on the positive film print).
When filming or photographing people, it is common to line the body up to a vertical line and the person's eyes to a horizontal line. If filming a moving subject, the same pattern is often followed, with the majority of the extra room being in front of the person (the way they are moving). [6]
Dot crawl (also known as chroma crawl or cross-luma) [1] [2] is a visual defect of color analog video standards when signals are transmitted as composite video, as in terrestrial broadcast television. It consists of moving checkerboard patterns which appear along horizontal color transitions (vertical edges).
The term "SmileBox" is a registered trademark [4] used to describe a type of letter-boxing for Cinerama films, such as on the Blu-ray release of How the West Was Won.The image is produced by using a map projection-like technique to approximate how the picture might look if projected onto a curved Cinerama screen.
In analog video, blanking occurs between horizontal lines and between frames. In raster scan equipment, an image is built up by scanning an electron beam from left to right across a screen to produce a visible trace of one scan line, reducing the brightness of the beam to zero (horizontal blanking), moving it back as fast as possible to the left of the screen at a slightly lower position (the ...
Video is encoded with the AVC/H.264 compression scheme. Audio is encoded with the AAC codec. The compressed audio and video are multiplexed into a QuickTime file. To reduce data rate and hardware requirements, video frame has size of 960 horizontal by 540 vertical pixels with pixel aspect ratio of 1:1, which results in 16:9 display aspect ratio.
Video loop of isallobars showing the motion of a cold front. An isobar (from Ancient Greek βάρος (baros) 'weight') is a line of equal or constant pressure on a graph, plot, or map; an isopleth or contour line of pressure.
