Over a long period in the late 2000s and early 2010s, the computer industry switched from 4:3 to 16:9 as the most common aspect ratio for monitors and laptops. The Community fund for the 16:9 Action Plan amounted to €228,000,000. In 1993, the European Union instituted the 16:9 Action Plan, to accelerate the development of the advanced television services in 16:9 aspect ratio, both in PALplus (compatible with regular PAL broadcasts) and also in HD-MAC (an early HD format). This has similarities to a filming technique called open matte. Content creators frame critical content or graphics to fit within the 1.33:1 raster space. Conversely it is quite common to use a technique known as center-cutting, to approach the challenge of presenting material shot (typically 16:9) to both an HD and legacy 4:3 audience simultaneously without having to compromise image size for either audience. Most 4:3 (1.3 3:1) and 2.40:1 video is now recorded using a ' shoot and protect' technique that keeps the main action within a 16:9 (1.7 7:1) inner rectangle to facilitate HD broadcast. While 16:9 (1.7 7:1) was initially selected as a compromise format, the subsequent popularity of HDTV broadcast has solidified 16:9 as perhaps the most common video aspect ratio in use. Applying the same geometric mean technique to 16:9 and 4:3 yields an aspect ratio of around 1.5396:1, sometimes approximated as 14:9 (1.5 5:1), which is likewise used as a compromise between these ratios. The value found by Powers is exactly the geometric mean of the extreme aspect ratios, 4:3 and 2.35:1, 47 15 ≈ 1.77 which is coincidentally close to 16:9. When overlapped with their center points aligned, he found that all of those aspect ratio rectangles fit within an outer rectangle with an aspect ratio of 1.7 7:1 and all of them also covered a smaller common inner rectangle with the same aspect ratio 1.77:1. Powers cut out rectangles with equal areas, shaped to match each of the popular aspect ratios.

The popular choices in 1980 were 4:3 (based on TV standard's ratio at the time), 15:9 (the European 'flat' 1.6 6:1 ratio), 1.85:1 (the American 'flat' ratio) and 2.35:1 (the CinemaScope/ Panavision) ratio for anamorphic widescreen. Powers, a member of the SMPTE Working Group on High-Definition Electronic Production, first proposed the 16:9 (1.7 7:1) aspect ratio in 1984, when nobody was creating 16:9 videos. The calculation considers the extreme rectangles, where m and n are multipliers to maintain their respective aspect ratios and areas.ĭr. DVD producers can also choose to show even wider ratios such as 1.85:1 and 2.40:1 within the 16:9 DVD frame by hard matting or adding black bars within the image itself.ĭerivation of the 16:9 aspect ratioThe main figure shows 4:3, 1.85:1, and 2.35:1 rectangles with the same area A, and 16:9 rectangles that covers (black) or is common to (grey) them. Many digital video cameras have the capability to record in 16:9, and 16:9 is the only widescreen aspect ratio natively supported by the DVD standard. Japan's Hi-Vision originally started with a 5:3 (1.6 6:1) ratio but converted when the international standards group introduced a wider ratio of 16 to 9. It has replaced the 'fullscreen' 4:3 aspect ratio.ġ6:9 (1.7 7:1) (said as sixteen by nine or sixteen to nine) is the international standard format of HDTV, non-HD digital television and analog widescreen television systems PALplus and Wide-aspect Clear-vision.

Once seen as exotic, since 2009, it has become the most common aspect ratio for televisions and computer monitors, and is also the international standard image format for UHD, HDTV, Full HD and SD digital television. Just thinking out loud here a bit, hope that’s okay here.An LCD television set with a 16:9 image ratio.ġ6:9 (1.7 7:1) is a widescreen aspect ratio with a width of 16 units and height of 9.

I kind of want to choose one export and stick with it to keep things simple for myself. Does that sound like a good idea? And I think that’s 16:9 aspect ratio. (List of common resolutions (and correlating aspect ratios?)Įdit: I think perhaps I’ll just go with 1280 × 720 for everything. Testing the results on my computer and tvĮdit: Also wondering what may be advantages to aspect ratio 16:9 over 4:3 if any? This point I’m just trusting some of the export presets and hoping for the best, then I’d like to hear any ideas about how and when calculating aspect ratios may beĮdit: I’m also trying to understand the relationship between resolution and aspect ratio.Įdit: I really have no idea what resolutions or aspect ratios to export my videos at, so at I’m just wondering how this calculator can help me when using Shotcut.
