While 16:9 (1.7 7:1) was initially selected as a compromise format, the subsequent popularity of HD broadcast has solidified 16:9 as perhaps the most common video aspect ratio in use. [7] Most 4:3 (1.3 3:1) and 21:9 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 ...
The difference is that whilst D1 has a 4:3 aspect ratio 960H has a 16:9 widescreen aspect ratio. The extra pixels are used to form the increased area to the sides of the D1 image. The pixel density of 960H is identical to standard D1 resolution so it does not give any improvement in image quality, merely a wider aspect ratio.

The favored aspect ratio of mass-market display industry products has changed gradually from 4:3, then to 16:10, then to 16:9, and has now changed to 18:9 for smartphones. [7] [needs update] The 4:3 aspect ratio generally reflects older products, especially the era of the cathode ray tube (CRT).
Unlike standard DVD-Video recordings, the aspect ratio (4:3 or 16:9) is contained in the .VRO file itself as part of the video stream. Thus DVD-VR supports mixed format presentations within a single .VRO file. Contrast DVD-Video where the aspect ratio is coded into the accompanying .IFO file and thus a single .
This aspect ratio was chosen as the geometric mean between 4:3 and 2.35:1, an average of the various aspect ratios used in film. [3] While 16:9 is well-suited for modern HDTV broadcasts , older 4:3 video has to be either padded with bars on the left and right side (pillarboxed), cropped or stretched, while movies shot with wider aspect ratios ...
The same frame size is used for 4:3 and 16:9 frame aspect ratios, resulting in different pixel aspect ratios for fullscreen and widescreen video. [ 8 ] [ 9 ] Prior to the DCT compression stage, chroma subsampling is applied to the source video in order to reduce the amount of data to be compressed.
Many digital video cameras have the capability to record in 16:9 (= 4 2:3 2), and 16:9 is the only widescreen aspect ratio natively supported by the DVD standard. DVD producers can also choose to show even wider ratios such as 1.66:1, 1.75:1, 1.77:1 and 1.78:1 [ 1 ] within the 16:9 DVD frame by hard matting or adding black bars within the image ...
