Home Video. Many televisions have the ability to magnify 2.39:1 and other widescreen formats in order to use more area on displays that aren't as wide.Digital Cinema Packages (DCP). The chosen resolution setting and aspect ratio may also need to conform with a distribution standard.

The region outside the frame guide (the "look-around area") can be monitored during capture to ensure that boom microphones, camera operators and similar objects remain outside the full frame. USING FRAME GUIDES WITH REDįrame guides are a helpful way to compose for a specific aspect ratio without necessarily recording at that aspect ratio. Use the Crop Factor Tool on red.com for additional guidance with aspect ratios. Capturing the full frame also means that a crop can always be expanded later if a different aspect ratio is needed„thereby enhancing as opposed to reducing clarity and sharpness. Other times, using a conservative aspect ratio (such as 2:1 even when outputting for 2.39:1) provides a good compromise between conserving storage space and being able to recompose. Many cinematographers therefore capture the full frame all the time, but compose for their intended output aspect ratio. Furthermore, the composition cannot be changed in post-production without also compromising resolution.
However, if a different aspect ratio is needed afterwards, the only options are cropping or padding. With television, the formats became 4:3 with standard definition and later 16:9 with high definition, which at 1.78:1 was a close match to 1.85:1 widescreen cinema.
VIDEO STANDARDSĮventually cinema converged on two leading standards: a normal 1.85:1 widescreen and an anamorphic 2.39:1 widescreen. Throughout this timeframe, cinema generally remained wider than television. Aspect ratios remained diverse for several decades, in part because of various new audio technologies, but also because theaters had to get equipped with new masks and projectors. The "Academy" standard persisted until the development of television drove film studios to distinguish themselves using even wider aspect ratios in the 1950s, such as Cinerama (2.66:1) and VistaVision (up to 2:1). By 1932, the Academy of Motion Pictures agreed to revert back to a wider standard of 1.375:1. This then had to narrow slightly to 1.17:1 due to the unanticipated rise of "talkies" on PhonoFilm, which required space for the audio track. In the early days, 1.33:1 (4:3) was the most commonly used aspect ratio for 35mm silent films, which in turn was chosen because 70mm film was already being mass-produced for still photography.
