![]() The process of converting 24-frame-per-second film to video by repeating one film frame as three fields, then the next film frame as two fieldsĪn uncommon variation of 2-3 pulldown, where the first film frame is repeated for 3 fields instead of two. When 24-fps film is converted via 2:2 pulldown to 25-fps 625/50 PAL video, the film runs 4 percent faster than normal. The process of transferring 24-frame-per-second film to video by repeating each film frame as two video fields. 16:9 supporters state that the wider picture corresponds much better to the human visual field than the almost square 4:3. ![]() It is wider than the standard 4:3 aspect ratio. The frame rate in hertz can be either implied by the context or specified after the letter p (such as 1080p30, meaning 30 frames per second).Īspect ratio most commonly known as widescreen or letterbox. The term usually assumes a widescreen aspect ratio of 16:9, implying a horizontal (display) resolution of 1920 dots across and a frame resolution of 1920 × 1080 or over two million pixels. The number 1080 represents 1,080 lines of vertical resolution, while the letter p stands for progressive scan or non-interlaced. Both variants can be transported by both major digital television formats, ATSC and DVB.ġ080p is the shorthand name for a category of video modes. The two field rates in common use are 50 and 60 Hz, with the former (1080i50) generally being used in traditional PAL and SECAM countries (Europe, Australia, much of Asia, Africa), the latter (1080i60) in traditional NTSC countries (e.g. The field rate (not the frame rate) in hertz can be either implied by the context or specified after the letter i. The term usually assumes a widescreen aspect ratio of 16:9, implying a horizontal resolution of 1920 pixels and a frame resolution of 1920 × 1080 or about 2.07 million pixels, and a field resolution of 1920 × 1080 / 2 (because it's interlaced) or about 1.04 million pixels. 1080i is considered to be an HDTV video mode. The number 1080 stands for 1080 lines of vertical resolution, while the letter i stands for interlaced or non-progressive scan.
