The resolution of 960H depends on whether the equipment is PAL or NTSC based: 960H represents 960 x 576 (PAL) or 960 x 480 (NTSC) pixels. [29] 960H represents an increase in pixels of some 30% over standard D1 resolution, which is 720 x 576 pixels (PAL), or 720 x 480 pixels (NTSC). The increased resolution over D1 comes as a result of a longer ...
720p (720 lines progressive) is a progressive HD signal format with 720 horizontal lines/1280 columns and an aspect ratio (AR) of 16:9, normally known as widescreen HD (1.78:1). All major HD broadcasting standards (such as SMPTE 292M ) include a 720p format, which has a resolution of 1280×720.
The next lower standard resolution (for widescreen) before it is WSXGA+, which is 1680 × 1050 pixels (1,764,000 pixels, or 30.61% fewer than WUXGA); the next higher resolution widescreen is an unnamed 2304 × 1440 resolution (supported by the above GDM-FW900 and A7217A) and then the more common WQXGA, which has 2560 × 1600 pixels (4,096,000 ...

[53] [54] YouTube developed its own chip, called "Argos", to help with encoding higher resolution videos in 2021. [55] In April 2023, YouTube began offering some videos in an enhanced bitrate "1080p Premium" option for YouTube Premium subscribers on iOS. [56] In August 2023, the feature became available to subscribers on desktop platforms. [57]
In general, 720p is more accurate with fast action, because it progressively scans frames, instead of the 1080i, which uses interlaced fields and thus might degrade the resolution of fast images. 720p is used more for Internet distribution of high-definition video, because computer monitors progressively scan; 720p video has lower storage ...
The 720p format produces 59.94/50 or 29.97/25 1280×720p images, not squeezed, so that no expansion or squeezing of the image is necessary. This confusion was industry-wide in the early days of digital video software, with much software being written incorrectly, the developers believing that only 29.97 images were expected each second, which ...
