As you can see, a 1:1,66 or 1:1,85 film will have black stripes at the top
and bottom of the TV frame, unless the film is tranferred "pan-and-scan", i.e.
enlarged to fill the entire screen. This is seldom done with "flat" images, but
often with anamorphic "scope" films - these are optically "squeezed" by shooting
through a special lens.
The markings on the diagram above shows all the important camera, projection
and TV scanning areas. Below are the exact dimensions of some of the areas, and
also the "safe" areas for TV - i.e the areas iside which all action (or titles)
should be kept. I consider these "safe areas" rather conservative. Modern TV
sets usually do not cut off as much. But they are drawn here accoding to the
1992 standard...
