It is also easier to perform high-quality 50↔60 Hz conversion and slow-motion clips with progressive video.Ī 720p60 (720p at 59.94 Hz) video has advantage over 480i and 1080i60 (29.97/30 frame/s, 59.94/60 Hz) in that it comparably reduces the number of 3:2 artifacts introduced during transfer from 24 frame/s film.
Progressive scanning reduces the need to prevent flicker by anti-aliasing single high contrast horizontal lines. No proposed or existing broadcast standard permits 720 interlaced lines in a video frame at any frame rate. However, in some cases it is incorrectly presented as an actual alternative format to 720p.
Typically, it is a typographical error in which the author is referring to the 720p HDTV format. The term assumes a widescreen aspect ratio of 16:9, thus implying a resolution of 1280×720 px (0.9 megapixels).ħ20i (720 lines interlaced) is an erroneous term found in numerous sources and publications. When broadcast at 60 frames per second, 720p features the highest temporal resolution possible under the ATSC and DVB standards. The number 720 stands for the 720 horizontal scan lines of image display resolution (also known as 720 pixels of vertical resolution). The frame rate is standards-dependent, and for conventional broadcasting appears in 50 progressive frames per second in former PAL/SECAM countries ( Europe, Australia, others), and 59.94 frames per second in former NTSC countries ( North America, Japan, Brazil, others). All major HDTV broadcasting standards (such as SMPTE 292M) include a 720p format, which has a resolution of 1280×720 however, there are other formats, including HDV Playback and AVCHD for camcorders, that use 720p images with the standard HDTV resolution.
This chart shows the most common display resolutions, 720p being one of the 16:9 formats shown in blue.ħ20p ( 1280×720 px also called HD ready, standard HD or just HD) is a progressive HDTV signal format with 720 horizontal lines/1280 columns and an aspect ratio (AR) of 16:9, normally known as widescreen HDTV (1.78:1).
