Tape



  • https://en.wikipedia.org/wiki/Quadruplex_videotape - 2″ quad, or just quad, for short) is the first practical and commercially successful analog recording videotape format. It was developed and released for the broadcast television industry in 1956 by Ampex, an American company based in Redwood City, California. The first videotape recorder using this format was built and created in the same year. This format revolutionized broadcast television operations and television production, since the only recording medium available to the TV industry before then was film used for kinescopes, which was much more costly to utilize and took time to develop at a film laboratory. In addition, kinescope images were usually of obviously inferior quality to the live television broadcast images they recorded, whereas quadruplex videotape preserved almost all the image detail of a live broadcast.

Since most United States West Coast network broadcast delays done by the television networks at the time were done with film kinescopes that needed time for developing, the networks wanted a more practical, cost-effective, and quicker way to time-shift television programming for later airing on the West Coast. Broadcasters also sought a recording medium that was not as costly or time-consuming to edit and develop as film. Faced with these challenges, broadcasters sought to adapt magnetic tape recording technology (already in use for recording audio) for use with television as well.

Analogue

Composite

  • https://en.wikipedia.org/wiki/Composite_video - is one channel analog video transmission (without audio) that carries standard definition video typically at 480i or 576i resolution. Video information is encoded on one channel, unlike the higher-quality S-video (two channels) and the even higher-quality component video (three or more channels). Composite video is usually in standard formats such as NTSC, PAL, and SECAM and is often designated by the initials CVBS, for color, video, blanking and sync, or simply as video.

S-Video

  • https://en.wikipedia.org/wiki/S-Video - also known as separate video and Y/C, a signaling standard for standard definition video, typically 480i or 576i. By separating the black-and-white and coloring signals, it achieves better image quality than composite video, but has lower color resolution than component video.

Component

  • https://en.wikipedia.org/wiki/Component_video - a video signal that has been split into two or more component channels. In popular use, it refers to a type of component analog video (CAV) information that is transmitted or stored as three separate signals. When used without any other qualifications the term component video usually refers to analog YPBPR component video with sync on luma.

SCART

  • https://en.wikipedia.org/wiki/SCART - (from Syndicat des Constructeurs d'Appareils Radiorécepteurs et Téléviseurs – Radio and Television Receiver Manufacturers' Association) is a French-originated standard and associated 21-pin connector for connecting audio-visual (AV) equipment. In Europe, SCART used to be the most common method of connecting AV equipment, and was a standard connector for such devices; it was far less common elsewhere. As it was designed to carry analog standard-definition content, SCART has become obsolete with the introduction of new digital standards such as HDMI and DisplayPort. HDMI-CEC is derived from SCART's AV.link.[citation needed] However, SCART Connection can also support HD signals like 480p, 720p, 1080i, 1080p, if the SCART connection of a device is designed to support YPbPr connection, but this configuration is rare. The same for multichannel audio, but even this configuration remains rare, as it is not standardized.

D-Terminal

  • https://en.wikipedia.org/wiki/D-Terminal - a type of analog video connector found on Japanese consumer electronics, typically HDTV, DVD, Blu-ray, D-VHS and HD DVD devices. It was developed by the EIAJ (Electronic Industry Association of Japan) in its standard, RC-5237, for use in digital satellite broadcast tuners. In appearance it is a small flat trapezic connector, the same connector as the AAUI connector used by Apple Computer for some time to connect to ethernet. Some items sold outside Japan use the connector as well. Notable examples are Canon's XH-A1 DVC high-definition camcorder and Panasonic's AG-HVX200 DVCPro HD camcorder.

TRRS

  • https://en.wikipedia.org/wiki/Phone_connector_(audio)#Video - Equipment requiring video with stereo audio input/output sometimes uses 3.5 mm TRRS connectors. Two incompatible variants exist, of 15 millimetres (0.59 in) and 17 mm (0.67 in) length, and using the wrong variant may either simply not work, or could cause physical damage.

VGA

SDI

  • https://en.wikipedia.org/wiki/Serial_digital_interface - SDI, a family of digital video interfaces first standardized by SMPTE (The Society of Motion Picture and Television Engineers) in 1989. For example, ITU-R BT.656 and SMPTE 259M define digital video interfaces used for broadcast-grade video. A related standard, known as high-definition serial digital interface (HD-SDI), is standardized in SMPTE 292M; this provides a nominal data rate of 1.485 Gbit/s.

DVI

  • https://en.wikipedia.org/wiki/Digital_Visual_Interface - DVI - a video display interface developed by the Digital Display Working Group (DDWG). The digital interface is used to connect a video source, such as a video display controller, to a display device, such as a computer monitor. It was developed with the intention of creating an industry standard for the transfer of digital video content. The interface is designed to transmit uncompressed digital video and can be configured to support multiple modes such as DVI-A (analog only), DVI-D (digital only) or DVI-I (digital and analog). Featuring support for analog connections, the DVI specification is compatible with the VGA interface. This compatibility, along with other advantages, led to its widespread acceptance over competing digital display standards Plug and Display (P&D) and Digital Flat Panel (DFP). Although DVI is predominantly associated with computers, it is sometimes used in other consumer electronics such as television sets and DVD players.

HDMI

  • https://en.wikipedia.org/wiki/HDMI - High-Definition Multimedia Interface is a proprietary audio/video interface for transmitting uncompressed video data and compressed or uncompressed digital audio data from an HDMI-compliant source device, such as a display controller, to a compatible computer monitor, video projector, digital television, or digital audio device. HDMI is a digital replacement for analog video standards.

HDMI implements the EIA/CEA-861 standards, which define video formats and waveforms, transport of compressed, uncompressed, and LPCM audio, auxiliary data, and implementations of the VESA EDID. CEA-861 signals carried by HDMI are electrically compatible with the CEA-861 signals used by the digital visual interface (DVI). No signal conversion is necessary, nor is there a loss of video quality when a DVI-to-HDMI adapter is used. The CEC (Consumer Electronics Control) capability allows HDMI devices to control each other when necessary and allows the user to operate multiple devices with one handheld remote control device.

Several versions of HDMI have been developed and deployed since initial release of the technology but all use the same cable and connector. Other than improved audio and video capacity, performance, resolution and color spaces, newer versions have optional advanced features such as 3D, Ethernet data connection, and CEC (Consumer Electronics Control) extensions. Production of consumer HDMI products started in late 2003. In Europe either DVI-HDCP or HDMI is included in the HD ready in-store labeling specification for TV sets for HDTV, formulated by EICTA with SES Astra in 2005. HDMI began to appear on consumer HDTVs in 2004 and camcorders and digital still cameras in 2006. As of January 6, 2015 (twelve years after the release of the first HDMI specification), over 4 billion HDMI devices have been sold.


DisplayPort

  • https://en.wikipedia.org/wiki/DisplayPort - a digital display interface developed by a consortium of PC and chip manufacturers and standardized by the Video Electronics Standards Association (VESA). The interface is primarily used to connect a video source to a display device such as a computer monitor, and it can also carry audio, USB, and other forms of data. DisplayPort was designed to replace VGA, DVI, and FPD-Link. The interface is backward compatible with legacy interfaces, such as HDMI and DVI, through the use of either active or passive adapters.

Interlaced

  • https://en.wikipedia.org/wiki/Interlaced_video - a technique for doubling the perceived frame rate of a video display without consuming extra bandwidth. The interlaced signal contains two fields of a video frame captured at two different times. This enhances motion perception to the viewer, and reduces flicker by taking advantage of the phi phenomenon. This effectively doubles the time resolution (also called temporal resolution) as compared to non-interlaced footage (for frame rates equal to field rates). Interlaced signals require a display that is natively capable of showing the individual fields in a sequential order. CRT displays and ALiS plasma displays are made for displaying interlaced signals. Interlaced scan refers to one of two common methods for "painting" a video image on an electronic display screen (the other being progressive scan) by scanning or displaying each line or row of pixels. This technique uses two fields to create a frame. One field contains all odd-numbered lines in the image; the other contains all even-numbered lines.

MPEG-2

  • https://en.wikipedia.org/wiki/MPEG-2 - a standard for "the generic coding of moving pictures and ISO/IEC 13818 MPEG-2 at the ISO Store. It describes a combination of lossy video compression and lossy audio data compression methods, which permit storage and transmission of movies using currently available storage media and transmission bandwidth. While MPEG-2 is not as efficient as newer standards such as H.264 and H.265/HEVC, backwards compatibility with existing hardware and software means it is still widely used, for example in over-the-air digital television broadcasting and in the DVD-Video standard.


H.264

  • H.264/MPEG-4 AVC is a block-oriented motion-compensation-based codec standard developed by the ITU-T Video Coding Experts Group (VCEG) together with the ISO/IEC JTC1 Moving Picture Experts Group (MPEG). The project partnership effort is known as the Joint Video Team (JVT). The ITU-T H.264 standard and the ISO/IEC MPEG-4 AVC standard (formally, ISO/IEC 14496-10 – MPEG-4 Part 10, Advanced Video Coding) are jointly maintained so that they have identical technical content. H.264 is perhaps best known as being one of the codec standards for Blu-ray Discs; all Blu-ray Disc players must be able to decode H.264. It is also widely used by streaming internet sources, such as videos from Vimeo, YouTube, and the iTunes Store, web software such as the Adobe Flash Player and Microsoft Silverlight, and also various HDTV broadcasts over terrestrial (ATSC, ISDB-T, DVB-T or DVB-T2), cable (DVB-C) and satellite (DVB-S and DVB-S2).

H.265


  • x265 - The goal of x265 is to become the best open source H.265/HEVC encoder,with the highest compression efficiency at the highest performance,while also allowing commercial use via a dual GPL and commercial license. In a nutshell, we would like to reproduce x264's successful development model for HEVC. [1]

VP8

  • https://en.wikipedia.org/wiki/VP8 - an open and royalty free video compression format owned by Google and created by On2 Technologies as a successor to VP7. In May 2010, after the purchase of On2 Technologies, Google provided an irrevocable patent promise on its patents for implementing the VP8 format, and released a specification of the format under the Creative Commons Attribution 3.0 license. That same year, Google also released libvpx, the reference implementation of VP8, under the revised BSD license.

VP9

  • https://en.wikipedia.org/wiki/VP9 - an open and royalty-free[1] video coding format developed by Google. VP9 is a successor to VP8 and competes mainly with MPEG's High Efficiency Video Coding (HEVC/H.265). At first, VP9 was mainly used on Google's video platform YouTube. The emergence of the Alliance for Open Media, and its support for the ongoing development of the successor AV1, led to growing interest in the format.


AV1

  • Alliance for Open Media - founded by leading Internet companies focused on developing next-generation media formats, codecs and technologies.  Alliance members bring their collective technology and expertise to meet growing Internet demand for top-quality video, audio, imagery and streaming across devices of all kinds and for users worldwide. The initial project – AOMedia Video – pursues a new, royalty-free video codec specification and open source implementation based on the contributions of Alliance members and the broader developer community, along with binding specifications for media format, content encryption and adaptive streaming. Founding members are Amazon, Apple, ARM, Cisco, Facebook, Google, IBM, Intel, Microsoft, Mozilla, Netflix and NVIDIA.
  • https://en.wikipedia.org/wiki/AV1 - an open, royalty-free video coding format designed for video transmissions over the Internet. It is being developed by the Alliance for Open Media (AOMedia), a consortium of firms from the semiconductor industry, video on demand providers, and web browser developers, founded in 2015. AV1 is the primary contender for standardization by the video standard working group NetVC of the Internet Engineering Task Force (IETF). The group has put together a list of criteria to be met by the new video standard. It is meant to succeed its predecessor VP9 and compete with HEVC/H.265 from the Moving Picture Experts Group. AV1 can be used together with the audio format Opus in a future version of the WebM container format for HTML5 web video and WebRTC.

  • Encoding, Fast and Slow: Low-Latency Video Processing Using Thousands of Tiny Threads - First, we designed a framework to run general-purpose parallel computations on a commercial “cloud function” service. The system starts up thousands of threads in seconds and manages inter-thread communication. Second, we implemented a video encoder intended for fine-grained parallelism, using a functional-programming style that allows computation to be split into thousands of tiny tasks without harming compression efficiency. Our design reflects a key insight: the work of video encoding can be divided into fast and slow parts, with the “slow” work done in parallel, and only “fast” work done serially.

Scripting

  • AviSynth - a powerful tool for video post-production. It provides ways of editing and processing videos. AviSynth works as a frameserver, providing instant editing without the need for temporary files. AviSynth itself does not provide a graphical user interface (GUI), but instead relies on a script system that allows advanced non-linear editing. While this may at first seem tedious and unintuitive, it is remarkably powerful and is a very good way to manage projects in a precise, consistent, and reproducible manner. Because text-based scripts are human readable, projects are inherently self-documenting. The scripting language is simple yet powerful, and complex filters can be created from basic operations to develop a sophisticated palette of useful and unique effects.


  • VapourSynth - an application for video manipulation. Or a plugin. Or a library. It’s hard to tell because it has a core library written in C++ and a Python module to allow video scripts to be created. It came to be when I started thinking about alternative designs for Avisynth and most of it was written over a 3 month period. The software has been heavily inspired by Avisynth and aims to be a 21st century rewrite, taking advantage of the advancements computers have made since the late 90s. The main features compared to Avisynth are: Multithreaded – Frame level multithreading, Generalized Colorspaces – New Colorspaces can be specified at runtime, Per Frame Properties – Additional metadata can be attached to frames, Python Based – The scripting part is implemented as a Python module so you don’t have have to learn a special language, Support for video with format changes – Some video just can’t stick to one format or frame size VapourSynth can handle any kind of change

blind

  • blind - a suckless collection of command line video editing utilities. blind uses a raw video format with a simple container. A file begins with an plain-text line, containing the number of frames, the width, the height, and the pixel format, all separated by a single regular blank space, without and leading or tailing white space. After this line, which ends with an LF, there is a NUL-byte followed by the 4 characters “uivf” (unportable, interim video format). This head is followed by the video frame-by-frame with row-major frames. Pixels are independently encoded, and are encoded unscaled CIE XYZ with non-premultiplied alpha and without any transfer-function, with values stored in native doubles or optionally in native floats. These two configurations are the only options, but the container format is designed so this can be changed arbitrarily in the future.

Nageru

  • Nageru - a live video mixer. It takes in inputs from one or more video cards (any DeckLink PCI card via Blackmagic's drivers, and Intensity Shuttle USB3 and UltraStudio SDI USB3 cards via bmusb), mixes them together based on the operator's desire and a theme written in Lua, and outputs a high-quality H.264 stream over TCP suitable for further transcoding and/or distribution. Nageru is free software, licensed under the GNU General Public License, version 3 or later. Nageru aims to produce high-quality output, both in terms of audio and video, while still running on modest hardware. The reference system for two 720p60 inputs is a ThinkPad X240, ie. an ultraportable dual-core with a not-very-fast GPU. Nageru's performance scales almost linearly with the available GPU power; e.g., if you have a GPU that's twice as fast as mine (which is not hard to find at all these days; desktop GPUs are frequently more like 10x), going to 1080p60 will only cost you about 10% more CPU power.
