4 3

A 4 3 ratio is a popular aspect ratio for both widescreen and standard TV, as well as computer, laptop, and mobile device monitors. The 4 3 ratio is also known as square" or "standard" which has square groups of pixels, rather than the more common rectangular shape of 16:9 and 21:9. This aspect ratio was previously used in all digital cinema and is still in use through a variety of digital displays and projectors.



But a surprising development in the use of 4:3 has found it being used in the most recent Marvel Cinematic Universe miniseries, WandaVision. In that case, the use of 4:3 was an homage to television programs of the ‘50s, ‘60s, and ‘70s, as well as a way to depict Wanda’s created world versus the world outside of it (which is in 2.39:1). The video below talks about how these various aspect ratio uses and transitions helped the miniseries narratively.

Though they only trailed for 29 seconds, this one still counts as another come from behind victory to add to the Avalanche’s arsenal with a 6-0-1 record in all such games since the break. Finding comfort and belief in overcoming such situations will help down the line in the playoffs but the Avalanche have to start managing the puck and games better. (Source:



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).

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 film) to show with the standard projectors available at theaters, and was then masked in the projector to the US standard of 1.85:1. The format was briefly revived by Lucasfilm in the late 1970s for special effects work that required 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 to standard four-perforation formats, in addition to increased lab costs of 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.) (Source: en.wikipedia.org)
