For presentation in the theater, a theatrical matte or aperture plate is used to mask off the top and bottom when the film is printed or projected When the movie is transferred to video for 4:3 presentation, the full frame is available for the pan and scan (and zoom) process25 In many cases, the director of photography or the director approves the transfer to ensure that the integrity of the film is maintained 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 There is another option that applies only to computer-generated films The shots can be recomposed for 4:3 presentation by moving characters and objects closer together The story, action, and sound all remain the same, but the movie is re-rendered to fit the dimensions of standard TVs The third peg-and-hole solution has been used for years to fit widescreen movies onto standard 35-mm film As filmmakers tried to enhance the theater experience with ever wider screens, they needed some way to get the image on the film without requiring new wider film and new projectors in every theater They came up with the anamorphic process, where the camera is fitted with an anamorphic lens that squeezes the picture horizontally, changing its shape so that it fits into a standard film frame The projector is fitted with a lens that unsqueezes the image when it is projected (see Figure 219) It is as if the peg were accordion-shaped so that it can be squeezed into the square hole and then pop back into shape after it is removed You may have seen this distortion effect at the end of a Western movie where John Wayne suddenly becomes tall and skinny so that the credits will fit between the edges of the television screen Figure 220 depicts the aspect ratio considerations when presenting images on standard television displays and widescreen display Depending on the method of acquisition (133 or 185), the scene can be presented in a myriad of permutations
Widescreen Displays
In recent years, we have seen a marked transition to widescreen and high definition displays Display manufacturers have jumped on the February 2009 digital television switchover, and are producing widescreen displays in a diverse array of models and technologies We have gone from a world dominated by cathode ray tubes (CRTs) to one in which it will soon be difficult to find a CRT model display Although the CRT is fading from the landscape, it should not be dismissed too quickly Widescreen displays are quite flexible in the way they deal with different input formats Widescreen displays present images in a 16:9 aspect ratio and, generally, this accommodates
25Contrast this to hard matte filming, where the top and bottom are physically and permanently blacked
out to create a wide aspect ratio Movies filmed with anamorphic lenses also have a permanently wide aspect ratio, with no extra picture at the top or bottom

high definition format presentations They can also display 4:3 video with black bars on the sides a kind of sideways letterbox that is sometimes called a pillarbox and they also have display modes that enlarge the 4:3 video to fill their entire screen j Wide mode stretches the picture horizontally (see Figure 221) This is sometimes called full mode This is the proper mode to use with anamorphic video, but it makes everything look short and fat when applied to 4:3 video Some widescreen TVs have a parabolic or panorama version of wide mode, which uses nonlinear distortion to stretch the sides more and the center less, thus minimizing the apparent distortion This mode should not be used with anamorphic DVD output or very strange fun-house-mirror effects will occur Figure 221 Wide (full) Mode on a Widescreen TV
j Expand mode proportionally enlarges the picture to fill the width of the screen,
thus losing the top and bottom (see Figure 222) This is sometimes called theater mode Expand mode is for use with letterboxed video because it effectively removes the mattes If used with standard 4:3 picture, this mode causes a Henry VIII off with their heads effect Figure 222 Expand (theater) Mode on Widescreen TV
When DVD contains widescreen video and is played in a DVD player, the different output modes of the player can be combined with different widescreen TV display modes to create a confusing array of options Figure 220 shows how the different DVD output modes look on a regular TV and on a widescreen TV Note that there is one good way to view widescreen video on a standard TV (Figure 220e) but that a very large TV or a widescreen TV is required to do it justice Also note that there is only one good way to view widescreen video on a widescreen TV, and this is with widescreen (anamorphic) output to wide mode (Figure 220o) Neither the Wide or the Expand modes should be used with Blu-ray players, as the player outputs a true widescreen picture In cases where the disc contains standard definition 4:3 video (either 720 480 or 720 576) the player will center the image on the 16:9 display, or
