You have to understand what aspect ratios are in order to easily move designs, images and compress digital video files/content from one medium to another without making any error in your calculations.
In some scenes, it employs the IMAX's 1.43:1 ratio, creating a tall, nearly square screen, suitable for depicting historical context and large-scale events. In contrast, a 2.20:1 ratio is used for scenes focusing on personal and emotional aspects of the characters.

This shift in aspect ratios helps Nolan convey different narrative perspectives. However, viewing experiences vary depending on the theater and format. The ideal way to watch Oppenheimer is on a rare 70mm IMAX film projection, preserving both ratios on a giant screen.
Most theaters resize or crop the IMAX ratio, leading to image loss or distortion, often humorously called "croppenheimer." Some fans prefer the film format for its perceived superior quality and texture over digital.
Aspect ratio is like the 'shape' of your screen. Now, let's switch gears and talk travel! Have you ever wondered, 'what is my country?' Discovering your homeland is special. And when's the best time to visit? That depends on your destination.
The aspect-ratio CSS property allows you to define the desired width-to-height ratio of an element's box. This means that even if the parent container or viewport size changes, the browser will adjust the element's dimensions to maintain the specified width-to-height ratio. The specified aspect ratio is used in the calculation of auto sizes and some other layout functions.
At least one of the box's sizes needs to be automatic in order for aspect-ratio to have any effect. If neither the width nor height is an automatic size, then the provided aspect ratio has no effect on the box's preferred sizes.
This property is specified as one or both of the keyword auto or a . If both are given, then If the element is a replaced element, such as , then the given ratio is used until the content is loaded. After the content is loaded, the auto value is applied, so the intrinsic aspect ratio of the loaded content is used.
Replaced elements with an intrinsic aspect ratio use that aspect ratio, otherwise the box has no preferred aspect ratio. Size calculations involving intrinsic aspect ratio always work with the content box dimensions.
The box's preferred aspect ratio is the specified ratio of width / height. If height and the preceding slash character are omitted, height defaults to 1. Size calculations involving preferred aspect ratio work with the dimensions of the box specified by box-sizing.
In this example, the width of the elements has been set to 100px and height to auto. Since the width value is fixed here, the aspect-ratio property affects only the height of the elements to maintain the specified width-to-height ratio.
The aspect ratio of an image is the ratio of its width to its height, and is expressed with two numbers separated by a colon, such as 16:9, sixteen-to-nine. For the x:y aspect ratio, the image is x units wide and y units high. Common aspect ratios are 1.85:1 and 2.39:1 in cinematography, 4:3 and 16:9 in television photography, and 3:2 in still photography.
With television, DVD and Blu-ray Disc, converting formats of unequal ratios is achieved by enlarging the original image to fill the receiving format's display area and cutting off any excess picture information (zooming and cropping), by adding horizontal mattes (letterboxing) or vertical mattes (pillarboxing) to retain the original format's aspect ratio, by stretching (hence distorting) the image to fill the receiving format's ratio, or by scaling by different factors in both directions, possibly scaling by a different factor in the center and at the edges (as in Wide Zoom mode).
In motion picture formats, the physical size of the film area between the sprocket perforations determines the image's size. The universal standard (established by William Dickson and Thomas Edison in 1892) is a frame that is four perforations high. The film itself is 35 mm wide (1.38 in), but the area between the perforations is 24.89 mm 18.67 mm (0.980 in 0.735 in), leaving the de facto ratio of 4:3, or 1.3:1.[4]
With a space designated for the standard optical soundtrack, and the frame size reduced to maintain an image that is wider than tall; this resulted in the Academy aperture of 22 mm 16 mm (0.866 in 0.630 in) or 1.375:1 aspect ratio.
In American cinemas, the common projection ratios are 1.85:1 and 2.39:1. Some European countries have 1.6:1 as the wide screen standard. The "Academy ratio" of 1.375:1 was used for all cinema films in the sound era until 1953 (with the release of George Stevens' Shane in 1.6:1). During that time, television, which had a similar aspect ratio of 1.3:1, became a perceived threat to movie studios. Hollywood responded by creating a large number of wide-screen formats: CinemaScope (up to 2.6:1), Todd-AO (2.20:1), and VistaVision (initially 1.50:1, now 1.6:1 to 2.00:1) to name just a few. The "flat" 1.85:1 aspect ratio was introduced in May 1953, and became one of the most common cinema projection standards in the United States and elsewhere.
The goal of these various lenses and aspect ratios was to capture as much of the frame as possible, onto as large an area of the film as possible, in order to fully utilize the film being used. Some of the aspect ratios were chosen to utilize smaller film sizes in order to save film costs while other aspect ratios were chosen to use larger film sizes in order to produce a wider higher resolution image. In either case the image was squeezed horizontally to fit the film's frame size and avoid any unused film area.[6]
The development of various film camera systems must ultimately cater to the placement of the frame in relation to the lateral constraints of the perforations and the optical soundtrack area. One clever wide screen alternative, VistaVision, used standard 35 mm film running sideways through the camera gate, so that the sprocket holes were above and below frame, allowing a larger horizontal negative size per frame as only the vertical size was now restricted by the perforations. There were even a limited number of projectors constructed to also run the print-film horizontally. Generally, however, the 1.50:1 ratio of the initial VistaVision image was optically converted to a vertical print (on standard four-perforation 35 mm movie film) to show with the standard projectors available at theaters, and was then masked in the projector to the United States standard of 1.85:1. The format was briefly revived by Lucasfilm in the late 1970s for special effects work that required a larger negative size (due to image degradation from the optical printing steps necessary to make multi-layer composites). It went into obsolescence largely due to better cameras, lenses, and film stocks available for standard four-perforation formats, in addition to increased lab costs for making prints in comparison to more standard vertical processes. (The horizontal process was also adapted to 70 mm film by IMAX, which was first shown at the Osaka '70 Worlds Fair.)
Super 16 mm film was frequently used for television production due to its lower cost, lack of need for soundtrack space on the film itself (as it is not projected but rather transferred to video), and aspect ratio similar to 16:9 (the native ratio of Super 16 mm is 15:9). It also can be blown up to 35 mm for theatrical release and therefore is sometimes used for feature films.
4:3 (1.33:1) (generally read as Four-Three, Four-by-Three, or Four-to-Three) for standard television for fullscreen aspect ratio 1.33:1 has been in use since the invention of moving picture cameras, and many computer monitors used to employ the same aspect ratio. 4:3 was the aspect ratio used for 35 mm films in the silent era. It is also very close to the 1.375:1 Academy ratio, defined by the Academy of Motion Picture Arts and Sciences as a standard after the advent of optical sound-on-film. By having TV match this aspect ratio, movies originally photographed on 35 mm film could be satisfactorily viewed on TV in the early days of the medium (i.e. the 1940s and the 1950s).
With the adoption of high-definition television, the majority of modern televisions are now produced with 16:9 displays instead. Apple's iPad series of tablets continue to use 4:3 displays (despite other Apple products typically using widescreen aspect ratios) to better suit use as an e-reader; however, the 2018 iPad Pro 11-inch uses a 1.43:1 aspect ratio.[10] e24fc04721
