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:
- Rec.601, a Rec.601-compliant value, which is considered the real Pixel Aspect Ratio of standard-definition video of that type.
- 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:
“[Convey to your child] that you understand how hard it can be to lose a friend, that under the circumstances feeling sad, angry, hurt or rejected is perfectly normal, that the friendship had some good things and some bad things to it and that neither aspect should be overlooked. . . . Children should be helped to realize that in time theyll find other friendsbut they mustnt expect a new friend to replace a former one.”
—Myron Brenton (20th century)
“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 (19111980)
“There are ... two minimum conditions necessary and sufficient for the existence of a legal system. On the one hand those rules of behavior which are valid according to the systems ultimate criteria of validity must be generally obeyed, and on the other hand, its rules of recognition specifying the criteria of legal validity and its rules of change and adjudication must be effectively accepted as common public standards of official behavior by its officials.”
—H.L.A. (Herbert Lionel Adolphus)
“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)
