  • https://en.wikipedia.org/wiki/Zoopraxiscope - an early device for displaying moving images and is considered an important predecessor of the movie projector. It was conceived by photographic pioneer Eadweard Muybridge in 1879 (and built for him by January 1880 to project his famous chronophotographic pictures in motion and thus prove that these were authentic). Muybridge used the projector in his public lectures from 1880 to 1895. The projector used 16" glass disks onto which Muybridge had an unidentified artist paint the sequences as silhouettes. This technique eliminated the backgrounds and enabled the creation of fanciful combinations and additional imaginary elements. Only one disk used photographic images, of a horse skeleton posed in different positions. A later series of 12" discs, made in 1892–1894, used outlines drawn by Erwin F. Faber that were printed onto the discs photographically, then colored by hand. These colored discs were probably never used in Muybridge's lectures. All images of the known 71 disks, including those of the photographic disk, were rendered in elongated form to compensate the distortion of the projection. The projector was related to other projecting phenakistiscopes and used some slotted metal shutter discs that were interchangeable for different picture disks or different effects on the screen. The machine was hand-cranked. The device appears to have been one of the primary inspirations for Thomas Edison and William Kennedy Dickson's Kinetoscope, the first commercial film exhibition system. Images from all of the known seventy-one surviving zoopraxiscope discs have been reproduced in the book Eadweard Muybridge: The Kingston Museum Bequest (The Projection Box, 2004).


Film

  • https://en.wikipedia.org/wiki/Kinetoscope - an early motion picture exhibition device. The Kinetoscope was designed for films to be viewed by one individual at a time through a peephole viewer window at the top of the device. The Kinetoscope was not a movie projector, but introduced the basic approach that would become the standard for all cinematic projection before the advent of video, by creating the illusion of movement by conveying a strip of perforated film bearing sequential images over a light source with a high-speed shutter. A process using roll film was first described in a patent application submitted in France and the U.S. by French inventor Louis Le Prince. The concept was also used by U.S. inventor Thomas Edison in 1889, and subsequently developed by his employee William Kennedy Laurie Dickson between 1889 and 1892. Dickson and his team at the Edison lab also devised the Kinetograph, an innovative motion picture camera with rapid intermittent, or stop-and-go, film movement, to photograph movies for in-house experiments and, eventually, commercial Kinetoscope presentations.A prototype for the Kinetoscope was shown to a convention of the National Federation of Women's Clubs on May 20, 1891. The first public demonstration of the Kinetoscope was held at the Brooklyn Institute of Arts and Sciences on May 9, 1893. Instrumental to the birth of American movie culture, the Kinetoscope also had a major impact in Europe; its influence abroad was magnified by Edison's decision not to seek international patents on the device, facilitating numerous imitations of and improvements on the technology. In 1895, Edison introduced the Kinetophone, which joined the Kinetoscope with a cylinder phonograph. Film projection, which Edison initially disdained as financially nonviable, soon superseded the Kinetoscope's individual exhibition model. Many of the projection systems developed by Edison's firm in later years would use the Kinetoscope name.


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.


DVD

  • https://en.wikipedia.org/wiki/VOB - the container format in DVD-Video media. VOB can contain digital video, digital audio, subtitles, DVD menus and navigation contents multiplexed together into a stream form. Files in VOB format may be encrypted.

HD DVD

  • https://en.wikipedia.org/wiki/HD_DVD - (short for High Definition Digital Versatile Disc) is an obsolete high-density optical disc format for storing data and playback of high-definition video. Supported principally by Toshiba, HD DVD was envisioned to be the successor to the standard DVD format.On February 19, 2008, after a protracted format war with rival Blu-ray, Toshiba abandoned the format, announcing it would no longer manufacture HD DVD players and drives. The HD DVD Promotion Group was dissolved on March 28, 2008.

Signals

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


Digital


  • https://en.wikipedia.org/wiki/Uncompressed_video - is digital video that either has never been compressed or was generated by decompressing previously compressed digital video. It is commonly used by video cameras, video monitors, video recording devices , and in video processors that perform functions such as image resizing, image rotation, deinterlacing, and text and graphics overlay. It is conveyed over various types of baseband digital video interfaces, such as HDMI, DVI, DisplayPort and SDI. Standards also exist for the carriage of uncompressed video over computer networks.

Some HD video cameras output uncompressed video, whereas others compress the video using a lossy compression method such as MPEG or H.264. In any lossy compression process, some of the video information is removed, which creates compression artifacts and reduces the quality of the resulting decompressed video. When editing video, it is preferred to work with video that has never been compressed as this maintains the best possible quality, with compression performed after completion of editing. Uncompressed video should not be confused with raw video. Raw video represents largely unprocessed data captured by an imaging device.


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.


  • https://github.com/hdl-util/hdmi - SystemVerilog code for HDMI 1.4a video/audio output on an FPGA. Most free and open source HDMI source (computer/gaming console) implementations actually output a DVI signal, which HDMI sinks (TVs/monitors) are backwards compatible with. To support audio and other HDMI-only functionality, a true HDMI signal must be sent. The code in this repository lets you do that without having to license an HDMI IP block from anyone.

  • https://en.wikipedia.org/wiki/Consumer_Electronics_Control - a feature of HDMI designed to control HDMI connected devices by using only one remote controller; so, individual CEC enabled devices can command and control each other without user intervention, for up to 15 devices. For example, a television set remote controller can also control a set-top box and a DVD player.It is a one-wire bidirectional serial bus that is based on the CENELEC standard AV.link protocol to perform remote control functions. CEC wiring is mandatory, although implementation of CEC in a product is optional. It was defined in HDMI Specification 1.0 and updated in HDMI 1.2, HDMI 1.2a and HDMI 1.3a (which added timer and audio commands to the bus). USB to CEC adapters exist that allow a computer to control CEC-enabled devices.


  • https://en.wikipedia.org/wiki/Mobile_High-Definition_Link - an industry standard for a mobile audio/video interface that allows the connection of smartphones, tablets, and other portable consumer electronics devices to high-definition televisions (HDTVs), audio receivers, and projectors. The standard was designed to share existing mobile device connectors, such as Micro-USB, and avoid the need to add additional video connectors on devices with limited space for them. MHL connects to display devices either directly through special HDMI inputs that are MHL-enabled, or indirectly through standard HDMI inputs using MHL-to-HDMI adapters. MHL was developed by a consortium of five companies: Nokia, Samsung, Silicon Image, Sony and Toshiba.

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.

  • https://en.wikipedia.org/wiki/SCTE-35 - a joint ANSI/Society of Cable and Telecommunications Engineers standard that describes the inline insertion of cue tones in mpeg-ts streams. The full standard name is "Digital Program Insertion Cueing Message for Cable."SCTE-35 is used in the US to signal a local ad insertion opportunity in the transport stream, and in Europe to insert local TV programs (e.g. local news transmissions).Currently, SCTE-35 is erratically implemented. Different providers have different "interpretations" of the specification.





  • https://en.wikipedia.org/wiki/Extended_Display_Identification_Data - EDID and Enhanced EDID (E-EDID) are metadata formats for display devices to describe their capabilities to a video source (e.g. graphics card or set-top box). The data format is defined by a standard published by the Video Electronics Standards Association (VESA).The EDID data structure includes manufacturer name and serial number, product type, phosphor or filter type (as chromaticity data), timings supported by the display, display size, luminance data and (for digital displays only) pixel mapping data.DisplayID is a VESA standard targeted to replace EDID and E-EDID extensions with a uniform format suited for both PC monitor and consumer electronics devices.

  • https://en.wikipedia.org/wiki/DisplayID - a VESA standard for metadata describing display device capabilities to the video source. It is designed to replace E-EDID standard and EDID structure v1.4. The DisplayID standard was initially released in December 2007. Version 1.1 was released in March 2009 and was followed by version 1.2 released in August 2011. Version 1.3 was released in June 2013 and current version 2.0 was released in September 2017.

DisplayID uses variable-length structures of up to 256 bytes each, which encompass all existing EDID extensions as well as new extensions for 3D displays, embedded displays, Wide Color Gamut and HDR EOTF. DisplayID format includes several blocks which describe logical parts of the display such as video interfaces, display device technology, timing details and manufacturer information. Data blocks are identified with a unique tag. The length of each block can be variable or fixed to a specific number of bytes. Only the base data block is mandatory, while all extension blocks are optional. This variable structure is based on CEA EDID Extension Block Version 3 first defined in CEA-861-B. The DisplayID standard is freely available and is royalty-free to implement.

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.



3D

  • https://en.wikipedia.org/wiki/3D_film - also known as three-dimensional film, 3D film or S3D film) is a motion picture that enhances the illusion of depth perception, hence adding a third dimension. The most common approach to the production of 3D films is derived from stereoscopic photography. In this approach, a regular motion picture camera system is used to record the images as seen from two perspectives (or computer-generated imagery generates the two perspectives in post-production), and special projection hardware or eyewear is used to limit the visibility of each image to the viewer's left or right eye only. 3D films are not limited to theatrical releases; television broadcasts and direct-to-video films have also incorporated similar methods, especially since the advent of 3D television and Blu-ray 3D.3D films have existed in some form since 1915, but had been largely relegated to a niche in the motion picture industry because of the costly hardware and processes required to produce and display a 3D film, and the lack of a standardized format for all segments of the entertainment business. Nonetheless, 3D films were prominently featured in the 1950s in American cinema, and later experienced a worldwide resurgence in the 1980s and 1990s driven by IMAX high-end theaters and Disney-themed venues. 3D films became increasingly successful throughout the 2000s, peaking with the success of 3D presentations of Avatar in December 2009, after which 3D films again decreased in popularity.[2] Certain directors have also taken more experimental approaches to 3D filmmaking, most notably celebrated auteur Jean-Luc Godard in his films 3X3D and Goodbye to Language.


  • https://en.wikipedia.org/wiki/3D_television - television that conveys depth perception to the viewer by employing techniques such as stereoscopic display, multi-view display, 2D-plus-depth, or any other form of 3D display. Most modern 3D television sets use an active shutter 3D system or a polarized 3D system, and some are autostereoscopic without the need of glasses. As of 2019, most 3D TV sets and services are no longer available.


  • https://en.wikipedia.org/wiki/DVB_3D-TV - a new standard that partially came out at the end of 2010 which included techniques and procedures to send a three-dimensional video signal through actual DVB transmission standards (Cable, Terrestrial or Satellite). Currently there is a commercial requirement text for 3D TV broadcasters and Set-top box manufacturers, but no technical information is in there. Nowadays 3D television technology is already in its first steps regarding its standardization, now the major 3D market is in theaters and Blu-ray Disc players with stereoscopic systems, but in the near future it will be extended to diffusion, and later Free viewpoint television will come into our homes, which means the need of new coding and transmission standards.


  • https://en.wikipedia.org/wiki/Multiview_Video_Coding - MVC, also known as MVC 3D, is a stereoscopic video coding standard for video compression that allows for the efficient encoding of video sequences captured simultaneously from multiple camera angles in a single video stream. It uses the 2D plus Delta method and is an amendment to the H.264 (MPEG-4 AVC) video compression standard, developed jointly by MPEG and VCEG, with contributions from a number of companies, primarily Panasonic and LG Electronics. MVC formatting is intended for encoding stereoscopic (two-view) 3D video, as well as free viewpoint television and multi-view 3D television. The Stereo High profile has been standardized in June 2009; the profile is based on the MVC toolset and is used in stereoscopic Blu-ray 3D releases. MVC streams are backward compatible with H.264/AVC, which allows older video player devices and software decoders to decode MVC video streams while ignoring additional information for the second view, meaning that the stereoscopic image will not be available.

MPEG transport stream / ISO/IEC13818-1

  • https://en.wikipedia.org/wiki/MPEG_transport_stream - or simply transport stream (TS) is a standard digital container format for transmission and storage of audio, video, and Program and System Information Protocol (PSIP) data. It is used in broadcast systems such as DVB, ATSC and IPTV.Transport stream specifies a container format encapsulating packetized elementary streams, with error correction and synchronization pattern features for maintaining transmission integrity when the communication channel carrying the stream is degraded.Transport streams differ from the similarly-named MPEG program stream in several important ways: program streams are designed for reasonably reliable media, such as discs (like DVDs), while transport streams are designed for less reliable transmission, namely terrestrial or satellite broadcast. Further, a transport stream may carry multiple programs.Transport stream is specified in MPEG-2 Part 1, Systems, formally known as ISO/IEC standard 13818-1 or ITU-T Rec. H.222.0.

ISO/IEC14496-12

It is designed as a flexible, extensible format that facilitates interchange, management, editing and presentation of the media. The presentation may be local, or via a network or other stream delivery mechanism. The file format is designed to be independent of any particular network protocol while enabling support for them in general. It is used as the basis for other media file formats (e.g. container formats MP4 and 3GP).


.flv

  • https://en.wikipedia.org/wiki/Flash_Video - a container file format used to deliver digital video content (e.g., TV shows, movies, etc.) over the Internet using Adobe Flash Player version 6 and newer. Flash Video content may also be embedded within SWF files. There are two different Flash Video file formats: FLV and F4V. The audio and video data within FLV files are encoded in the same way as SWF files. The F4V file format is based on the ISO base media file format, starting with Flash Player 9 update 3. Both formats are supported in Adobe Flash Player and developed by Adobe Systems. FLV was originally developed by Macromedia. In the early 2000s, Flash Video was the de facto standard for web-based streaming video (over RTMP). Users include Hulu, VEVO, Yahoo! Video, metacafe, Reuters.com, and many other news providers.

Flash Video FLV files usually contain material encoded with codecs following the Sorenson Spark or VP6 video compression formats. As of 2010 public releases of Flash Player (collaboration between Adobe Systems and MainConcept) also support H.264 video and HE-AAC audio.

M-JPEG

  • https://en.wikipedia.org/wiki/Motion_JPEG - a video compression format in which each video frame or interlaced field of a digital video sequence is compressed separately as a JPEG image. Originally developed for multimedia PC applications, Motion JPEG enjoys broad client support: most major web browsers and players provide native support, and plug-ins are available for the rest. Software and devices using the M-JPEG standard include web browsers, media players, game consoles, digital cameras, IP cameras, webcams, streaming servers, video cameras, and non-linear video editors

Unlike the video formats specified in international standards such as MPEG-2 and the format specified in the JPEG still-picture coding standard, there is no document that defines a single exact format that is universally recognized as a complete specification of “Motion JPEG” for use in all contexts. This raises compatibility concerns about file outputs from different manufacturers. However, each particular file format usually has some standard on how M-JPEG is encoded. For example, Microsoft documents their standard format to store M-JPEG in AVI files, Apple documents how M-JPEG is stored in QuickTime files, RFC 2435 describes how M-JPEG is implemented in an RTP stream, and an M-JPEG CodecID is planned for the Matroska file format.


  • RFC 2435 - RTP Payload Format for JPEG-compressed Video - This memo describes the RTP payload format for JPEG video streams. The packet format is optimized for real-time video streams where codec parameters change rarely from frame to frame. This document is a product of the Audio-Video Transport working group within the Internet Engineering Task Force. Comments are solicited and should be addressed to the working group's mailing list at rem- conf@es.net and/or the author(s).


  • MJPEG Tools - The mjpeg programs are a set of tools that can do recording of videos and playback, simple cut-and-paste editing and the MPEG compression of audio and video under Linux.


MPEG-1

  • https://en.wikipedia.org/wiki/MPEG-1 - a standard for lossy compression of video and audio. It is designed to compress VHS-quality raw digital video and CD audio down to about 1.5 Mbit/s (26:1 and 6:1 compression ratios respectively) without excessive quality loss, making video CDs, digital cable/satellite TV and digital audio broadcasting (DAB) practical. Today, MPEG-1 has become the most widely compatible lossy audio/video format in the world, and is used in a large number of products and technologies. Perhaps the best-known part of the MPEG-1 standard is the first version of the MP3 audio format it introduced. The MPEG-1 standard is published as ISO/IEC 11172 – Information technology—Coding of moving pictures and associated audio for digital storage media at up to about 1.5 Mbit/s.


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 / MPEG-4

  • 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).





  • OpenH264 - Cisco has taken their H.264 implementation, and open sourced it under BSD license terms. Development and maintenance will be overseen by a board from industry and the open source community. Furthermore, we have provided a binary form suitable for inclusion in applications across a number of different operating systems, and make this binary module available for download from the Internet. We will not pass on our MPEG-LA licensing costs for this module, and based on the current licensing environment, this will effectively make H.264 free for use on supported platforms.

H.265 / HVEC


  • 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. [3]


H.266 / VVC


FFV1

  • https://en.wikipedia.org/wiki/FFV1 - short for FF Video 1, is a lossless intra-frame video coding format. It can use either variable-length coding or arithmetic coding for entropy coding. The encoder and decoder are part of the free, open-source library libavcodec in the project FFmpeg since June 2003. FFV1 is also included in ffdshow and LAV Filters, which makes the video codec available to Microsoft Windows applications that support system-wide codecs over Video for Windows or DirectShow. FFV1 is particularly popular for its performance regarding speed and size, compared to other lossless preservation codecs, such as M-JPEG2000. The European Broadcasting Union lists FFV1 under the codec-family index "31" in their combined list of video codec references. It has been standardized at the IETF under RFC 9043

WMV

  • https://en.wikipedia.org/wiki/Windows_Media_Video - a series of video codecs and their corresponding video coding formats developed by Microsoft. It is part of the Windows Media framework. WMV consists of three distinct codecs: The original video compression technology known as WMV, was originally designed for Internet streaming applications, as a competitor to RealVideo. The other compression technologies, WMV Screen and WMV Image, cater for specialized content. After standardization by the Society of Motion Picture and Television Engineers SMPTE, WMV version 9 was adapted for physical-delivery formats such as HD DVD and Blu-ray Disc and became known as VC-1. Microsoft also developed a digital container format called Advanced Systems Format to store video encoded by Windows Media Video.

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.

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.


  • https://github.com/OpenVisualCloud/SVT-AV1 - an AV1-compliant encoder library core. The SVT-AV1 development is a work-in-progress targeting performance levels applicable to both VOD and Live encoding / transcoding video applications.

Distributed

  • 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.

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

  • 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.

Komposition

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.

These are companies which have helped artists create ground-breaking VFX shots on nearly every blockbuster movie.


  • OpenFX - an open standard for visual effects plug-ins. It allows plug-ins written to the standard to work on any application that supports the standard. This avoids the current per application fragmentation of plug-in development and support, which causes much heartache to everyone, plug-in developers, application developers and end users alike


FreeFrame

  • FreeFrame - Open Realtime Video Effects, provides a framework for developing video effects plugins and hosts on Windows, Linux and Mac OSX. Sample code is provided which compiles in Delphi, MSVC, GCC, Project Builder and Kylix.The plugins are initially intended for use in VJ ('Visual Jockey') applications. The project was initiated by developers from VJamm, Resolume and EffecTV. Freeframe support is now available for a range of video applications. Open - i.e.. not governed by a commercial organisation. CrossPlatform & CrossCompiler. Standardised. Technical independence.



  • FFRend - a renderer for Freeframe plugins. It allows you to chain any number of plugins together, automate their parameters using oscillators, and record the output to an AVI file. The input is a video (AVI/MPG), still image (BMP/JPG/GIF), or source plugin.Most VJ softwares support Freeframe, and can record their output, so what makes FFRend different? FFRend is optimized for content generation, whereas VJ softwares are typically optimized for live performance. The key difference is that FFRend never drops frames, even when your project is too CPU-intensive to be rendered in real time.It's also possible to perform with FFRend. The user interface is modular, dual-monitor is fully supported, and all parameters and oscillator settings can be controlled via MIDI. Version 2 also supports parallel processing on multi-core CPUs, for greatly improved frame rates.FFRend supports plugin authoring, which means you can export a FFRend project as a Freeframe plugin. The exported plugin is called a metaplugin, because it uses other plugins as components. A metaplugin can be used in any Freeframe-compatible host application, and behaves as if you were running the equivalent project in FFRend.FFRend is free, open-source software for Windows XP/Vista/Win7. It includes comprehensive help, an installer, and a simple demo project. If you want to render complex effects at high resolution, using chains of automated Freeframe plugins, FFRend is your friend.


  • https://github.com/leadedge/ShaderMaker - A source code template to build FreeframeGL 2.1 plugins for Resolume from GLSL Sandbox or ShaderToy shaders.During compilation, shader and image files are loaded into into resources and saved with the plugin. The plugin then accesses these resources when it loads. ShaderToy multiple buffers are not supported. This is a Windows project for Visual Studio 2017.



Frei0r

  • Frei0r - a minimalistic plugin API for video effects. The main emphasis is on simplicity for an API that will round up the most common video effects into simple filters, sources and mixers that can be controlled by parameters.

HasciiCam

  • https://github.com/jaromil/HasciiCam - Hasciicam makes it possible to have live ascii video on the web. It captures video from a tv card and renders it into ascii, formatting the output into an html page with a refresh tag or in a live ascii window or in a simple text file as well, giving the possiblity to anybody that has a bttv card. a linux box and a cheap modem line to show a live asciivideo feed that can be browsable without any need for plugin, java etc.

AviGlitch

  • AviGlitch - A Ruby library to destroy your AVI files.

Speed

slowmoVideo

  • https://github.com/slowmoVideo/slowmoVideo - an OpenSource program that creates slow-motion videos from your footage. But it does not simply make your videos play at 0.01× speed. You can smoothly slow down and speed up your footage, optionally with motion blur. How does slow motion work? slowmoVideo tries to find out where pixels move in the video (this information is called Optical Flow), and then uses this information to calculate the additional frames between the ones recorded by your camera.

Futatabi

  • Futatabi - multi-camera instant replay system with slow motion. It supports efficient real-time interpolation using optical flow, making for full-framerate output without having to use special high-framerate cameras. (Of course, interpolation can only take you so far, and the results will depend on the type of content.) Futatabi is currently in alpha. It is distributed and built together with Nageru.

MVTools

  • https://avisynth.nl/index.php/MVTools - plugin for AviSynth 2.6 is a collection of functions for estimation and compensation of objects motion in video clips. Motion compensation may be used for strong temporal denoising, advanced framerate conversions, image restoration and other tasks.

SVP

  • SVP - 60 fps / 120 fps HFR motion interpolation for Windows, macOS in mpv, VLC, Plex - $

motioninterpolation.vpy

  • motioninterpolation.vpy - Realtime motion interpolating playback in mpv. SVP now has a free (but proprietary) version of their software, which includes a GPU port of the MVTools functions, making this much less resource intense.

  • appleseed is a modern, open source, physically-based rendering engine for VFX and animation.


  • PixelStruct is an opensource tool for visualizing 3D scenes reconstructed from photographs. It uses the opensource structure-from-motion system Bundler, which is based on the same research as Microsoft Live Labs Photosynth.



  • Electric Sheep - a collaborative abstract artwork founded by Scott Draves. It's run by thousands of people all over the world, and can be installed on almost anything. When these computers "sleep", the Electric Sheep comes on and the computers communicate with each other by the internet to share the work of creating morphing abstract animations known as "sheep". Anyone watching one of these computers may vote for their favorite animations using the keyboard. The more popular sheep live longer and reproduce according to a genetic algorithm with mutation and cross-over. Hence the flock evolves to please its global audience. The Electric Sheep are a free and open source service. The Gold Sheep are an HD premium version.


  • vid.stab - Transcode video stabilization plugin. Imagine you captured a nice video with your camcorder, compact camera or even cell phone while skiing, cycling or whatever sports and the video is basically just jiggled. Modern cameras come along with hardware stabilisation, however this does not work if you have really strong vibrations - rather the contrary sometimes this mechanisms start to oscillate. Vid.Stab is your friend in this matter. It is integrated in transcode, ffmpeg (check also static builds) and kdenlive. It is designed to stabilize even strongly jiggled clips.


  • https://github.com/GafferHQ/gaffer - a VFX application that enables look developers, lighters, and compositors to easily build, tweak, iterate, and render scenes. Gaffer supports in-application scripting in Python and OSL, so VFX artists and technical directors can design shaders, automate processes, and build production workflows. An open-source project, Gaffer also provides an application framework for studios to design and create their own VFX production pipeline tools. Built using the Cortex libraries, Gaffer ships with a multi-threaded, deferred evaluation engine and a flexible user interface framework.
