Pixel Aspect Ratio - Pixel Aspect Ratios of Common Video Formats

Pixel Aspect Ratios of Common Video Formats

Pixel aspect ratio values for common standard-definition video formats are listed below. Note that for each video format, two different types of pixel aspect ratio values are listed:

  1. Rec.601, a Rec.601-compliant value, which is considered the real Pixel Aspect Ratio of standard-definition video of that type.
  2. Digital, which is roughly equivalent to Rec.601 and is more suitable to use in Digital Video Editing software.

Note that sources differ on PARs for common formats – for example, 576 lines (PAL) displayed at 4:3 (DAR) corresponds to either PAR of 12:11 (if 704×576, SAR = 11:9), or a PAR of 16:15 (if 720×576, SAR = 5:4). See references for sources giving both, and SDTV: Resolution for a table of storage, display and pixel aspect ratios.

Famous quotes containing the words aspect, ratios, common and/or video:

    Much literary criticism comes from people for whom extreme specialization is a cover for either grave cerebral inadequacy or terminal laziness, the latter being a much cherished aspect of academic freedom.
    John Kenneth Galbraith (b. 1908)

    Typography is not only a technology but is in itself a natural resource or staple, like cotton or timber or radio; and, like any staple, it shapes not only private sense ratios but also patterns of communal interdependence.
    Marshall McLuhan (1911–1980)

    No illusion is more crucial than the illusion that great success and huge money buy you immunity from the common ills of mankind, such as cars that won’t start.
    Larry McMurtry (b. 1936)

    I recently learned something quite interesting about video games. Many young people have developed incredible hand, eye, and brain coordination in playing these games. The air force believes these kids will be our outstanding pilots should they fly our jets.
    Ronald Reagan (b. 1911)
