Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual media. Video was first developed for mechanical television systems, which were quickly replaced by cathode-ray tube (CRT) systems which, in turn, were replaced by flat panel displays of several types.
Cinematography is the art of motion picture photography.
Slow motion is an effect in film-making whereby time appears to be slowed down. It was invented by the Austrian priest August Musger in the early 20th century. This can be accomplished through the use of high-speed cameras and then playing the footage produced by such cameras at a normal rate like 30 fps, or in post production through the use of software.
Bullet time is a visual effect or visual impression of detaching the time and space of a camera from that of its visible subject. It is a depth enhanced simulation of variable-speed action and performance found in films, broadcast advertisements, and realtime graphics within video games and other special media. It is characterized by its extreme transformation of both time, and of space. This is almost impossible with conventional slow motion, as the physical camera would have to move implausibly fast; the concept implies that only a "virtual camera", often illustrated within the confines of a computer-generated environment such as a virtual world or virtual reality, would be capable of "filming" bullet-time types of moments. Technical and historical variations of this effect have been referred to as time slicing, view morphing, temps mort and virtual cinematography.
"Doctor's Orders" is the sixteenth episode from the third season of the science fiction television series Star Trek: Enterprise. It's the sixty-eighth episode of the series, first airing on February 18, 2004.
"Force of Nature" is the 161st episode of the American science fiction television series Star Trek: The Next Generation. It is the ninth episode of the seventh season.
In video technology, 24p refers to a video format that operates at 24 frames per second frame rate with progressive scanning. Originally, 24p was used in the non-linear editing of film-originated material. Today, 24p formats are being increasingly used for aesthetic reasons in image acquisition, delivering film-like motion characteristics. Some vendors advertise 24p products as a cheaper alternative to film acquisition.
Play for Today is a British television anthology drama series, produced by the BBC and transmitted on BBC1 from 1970 to 1984. During the run, more than three hundred programmes, featuring original television plays, and adaptations of stage plays and novels, were transmitted. The individual episodes were between fifty and a hundred minutes in duration. A handful of these plays, including Rumpole of the Bailey, subsequently became television series in their own right.
A high-speed camera is a device capable of capturing moving images with exposures of less than 1/1,000 second or frame rates in excess of 250 fps. It is used for recording fast-moving objects as photographic images onto a storage medium. After recording, the images stored on the medium can be played back in slow motion. Early high-speed cameras used photographic film to record the high-speed events, but have been superseded by entirely electronic devices using an image sensor, recording, typically, over 1,000 fps onto DRAM, to be played back slowly to study the motion for scientific study of transient phenomena.
High-definition video is video of higher resolution and quality than standard-definition. While there is no standardized meaning for high-definition, generally any video image with considerably more than 480 vertical scan lines or 576 vertical lines (Europe) is considered high-definition. 480 scan lines is generally the minimum even though the majority of systems greatly exceed that. Images of standard resolution captured at rates faster than normal, by a high-speed camera may be considered high-definition in some contexts. Some television series shot on high-definition video are made to look as if they have been shot on film, a technique which is often known as filmizing.
1080p is a set of HDTV high-definition video modes characterized by 1,920 pixels displayed across the screen horizontally and 1,080 pixels down the screen vertically; the p stands for progressive scan, i.e. non-interlaced. The term usually assumes a widescreen aspect ratio of 16:9, implying a resolution of 2.1 megapixels. It is often marketed as Full HD or FHD, to contrast 1080p with 720p resolution screens. Although 1080p is sometimes informally referred to as 2K, these terms reflect two distinct technical standards, with differences including resolution and aspect ratio.
"Booby Trap" is the sixth episode of the third season of the American science fiction television series Star Trek: The Next Generation, the 54th episode overall, first broadcast on October 30, 1989. It is the first episode of any Star Trek series to be directed by a woman.
"The Catwalk" is the thirty-eighth episode of the science-fiction television series Star Trek: Enterprise. To survive a radiation storm, the entire crew of the Enterprise is forced to shelter inside one of the starship's warp nacelles. Tensions rise and the motives and strange behaviour of the passengers they took on are questioned.
AVCHD is a file-based format for the digital recording and playback of high-definition video. It is H.264 and Dolby AC-3 packaged into the MPEG transport stream, with a set of constraints designed around the camcorders.
Wild China is a six-part nature documentary series on the natural history of China, co-produced by the BBC Natural History Unit and China Central Television (CCTV) and filmed in high-definition (HD). It was screened in the UK on BBC Two from 11 May to 5 June 2008. The English narration was provided by Bernard Hill and the series produced by Phil Chapman for the BBC and Gao Xiaoping for CCTV. The Chinese version was broadcast under the title Beautiful China. In Canada, it was broadcast on CBC as part of the series The Nature of Things narrated by David Suzuki. Wild China was broadcast in Australia on ABC1 and ABC HD each Sunday at 7:30pm from 18 May 2008.
Life is a British nature documentary series created and produced by the BBC in association with The Open University. It was first broadcast as part of the BBC's Darwin Season on BBC One and BBC HD from October to December 2009. The series takes a global view of the specialised strategies and extreme behaviour that living things have developed in order to survive; what Charles Darwin termed "the struggle for existence". Four years in the making, the series was shot entirely in high definition.
Nature's Great Events is a wildlife documentary series made for BBC television, first shown in the UK on BBC One and BBC HD in February 2009. The series looks at how seasonal changes powered by the sun cause shifting weather patterns and ocean currents, which in turn create the conditions for some of the planet's most spectacular wildlife events. Each episode focuses on the challenges and opportunities these changes present to a few key species.
Earthflight is a British nature documentary that shows a flight from the view of the wings of birds across six continents, showing some of the world's greatest natural spectacles from a bird's-eye view. The BBC series was created by John Downer and narrated by David Tennant and consisted of six 60-minute episodes. The first episode aired on BBC One on 29 December 2011.
Life Story is a British natural-history television series with Mike Gunton, Rupert Barrington and Tom Hugh-Jones from the BBC Natural History Unit on the production team. The six-part series reveals the challenges faced by individual animals at different stages of their lives and was first broadcast on BBC One in 2014. The series is introduced and narrated by David Attenborough.
