This is a list of Avid DNxHD resolutions, mainly available in multiple HD encoding resolutions based on the frame size and frame rate of the media being encoded. The list below shows the available encoding choices for each of the available frame size and frame rate combinations. [1] [2] Its sister codec, Avid DNxHR, supports resolutions beyond ...
Effectively 1/16 the total resolution (1/4 in each dimension) of "Full HD", but with the height aligned to an 8-pixel "macroblock" boundary. Common in small-screen video applications, including portable DVD players and the Sony PSP. 480×272 (131k) 480 272 130,560 ~1% narrower than 16:9 (30:17 exact) Mac Mono 9" Original Apple Macintosh display
AV equipment manufacturers have adopted the term Full HD to mean a set can display all available HD resolutions up to 1080p. The term is misleading, however, because it does not guarantee the set is capable of rendering digital video at all frame rates encoded in source files with 1920 X 1080 pixel resolution.
To convert 24 frame/s film to 29.97 frame/s (presented as 59.94 interlaced fields per second) NTSC, a process called "3:2 pulldown" is used, in which every other film frame is duplicated across an additional interlaced field to achieve a framerate of 23.976 (the audio is slowed imperceptibly from the 24 frame/s source to match). This produces ...
FHD (Full HD) is the resolution 1920 × 1080 used by the 1080p and 1080i HDTV video formats. It has a 16:9 aspect ratio and 2,073,600 total pixels, i.e. very close to 2 megapixels, and is exactly 50% larger than 720p HD (1280 × 720) in each dimension for a total of 2.25 times as many pixels.
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. Alternative analog video transport technologies carrying higher resolutions than 960H include HD-TVI, HDCVI, and AHD.
A frame rate of 30 frame/s is often used for audio in America, Japan, and other countries that rely on a 60 Hz mains frequency and use the NTSC television standard. The European Broadcasting Union standard frame rate of 25 frame/s is used throughout Europe, Australia and wherever the mains frequency is 50 Hz and the PAL or SECAM television ...
The 1080-line system does not support progressive images at the highest frame rates of 50, 59.94 or 60 frames per second, because such technology was seen as too advanced at the time. The standard also requires 720-line video be progressive scan, since that provides better picture quality than interlaced scan at a given frame rate, and there ...
