Picture concepts.
1080p
1080p commonly describes progressive video with 1080 vertical picture lines, often using a 1920-by-1080 pixel grid.
Explore →4K UHD
Consumer 4K UHD usually describes a 3840-by-2160 picture or output grid, containing four times as many pixels as 1920-by-1080.
Explore →Upscaling
Upscaling resizes a lower-resolution image to a larger pixel grid.
Explore →Frame rate
Frame rate is the number of video pictures represented in one second, normally written as fps.
Explore →Refresh rate
Refresh rate describes how often a display updates its picture each second, expressed in hertz.
Explore →Frame-rate matching
Frame-rate matching is a playback function that selects a display timing suited to the video’s source frame rate.
Explore →Judder
Judder is visibly uneven motion caused by irregular presentation timing or cadence.
Explore →Dropped frames
Dropped frames are video pictures that are not presented when expected.
Explore →Interlacing
Interlacing is a video representation that divides a picture into alternating sets of lines called fields.
Explore →Deinterlacing
Deinterlacing converts interlaced fields into pictures suitable for a progressive screen.
Explore →Aspect ratio
Aspect ratio is the relationship between an image’s displayed width and height.
Explore →Pixel aspect ratio
Pixel aspect ratio describes the shape of a stored video sample: its width relative to its height when displayed.
Explore →Letterboxing
Letterboxing fits a wide image within a narrower display area by adding horizontal bars above and below it.
Explore →Overscan
Overscan is a display setting that enlarges an incoming picture enough to hide its outer edges.
Explore →Bit depth
Bit depth is the number of binary digits used to represent each component sample in an image or audio signal.
Explore →Chroma subsampling
Chroma subsampling reduces the spatial resolution of colour information relative to brightness information.
Explore →Compression artifacts
Compression artifacts are visible or audible errors introduced when a codec represents media with limited data or imperfect settings.
Explore →Macroblocking
Macroblocking is a visible block-shaped loss of detail commonly associated with compressed video.
Explore →Color banding
Color banding is the appearance of visible steps or contour lines in an area that should change smoothly in brightness or colour.
Explore →HDR
High dynamic range, or HDR, is a video presentation system that can describe a greater range of scene brightness than conventional standard dynamic range.
Explore →SDR
Standard dynamic range, or SDR, describes conventional video brightness presentation used by much broadcast television, older films and online media.
Explore →Tone mapping
Tone mapping adapts an image’s brightness relationships to the range that a destination can reproduce.
Explore →HDR10
HDR10 is an HDR presentation format associated with the PQ transfer function, 10-bit video and static HDR metadata.
Explore →HLG
Hybrid Log-Gamma, usually abbreviated HLG, is an HDR system developed for television production and distribution.
Explore →Dolby Vision
Dolby Vision is an HDR technology that combines compatible video profiles with metadata used in the presentation process.
Explore →Color gamut
A colour gamut is the range of colours that a signal system or display can represent.
Explore →Limited and full range
Limited and full range are conventions for assigning numerical video values to black, white and intermediate levels.
