Example text

For wider movies, pan and scan is more useful, but the original aspect ratio is lost, which goes against the spirit of a widescreen format. When going to the trouble of supporting DVD’s widescreen format, it seems silly to pan and scan inside it, but if the option is there, someone is bound to use it. 4. 85 to 16:9, a small amount of picture from the top and bottom of the full-frame film area can be included. This stays close to the original aspect ratio without requiring a matte, and the extra picture will be hidden in the overscan area on a widescreen TV or when panned and scanned by the DVD player.

Full control over how the picture is reframed is very important. For example, when the mattes are removed, close-up shots become medium shots, and the frame may need to be zoomed in to recreate the intimacy of the original shot. In a sense, the film is being composed anew for the new aspect. The pan and scan process has the disadvantage of losing some of the original picture but is able to make the most of the 4:3 television screen and is able to enlarge the picture to compensate for the smaller size and lower resolution as compared with a theater screen.

C. 66 movie, thin mattes are placed on the sides instead of at the top and bottom and generally will be hidden in the overscan area. 2. 85 movies, slicing 2 percent from each side is sufficient and probably will not be noticeable. 66 movies, except that about 3 percent is sliced off the top and off the bottom. 35 movie requires slicing 12 percent from each side. This procrustean approach throws away a quarter of the picture and is not a likely to be a popular solution. 3. Pan and scan to 16:9 The standard pan and scan technique can be used with a 16:9 window (as opposed to a 4:3 window) when transferring from film to DVD.
