Video logging is a process in which video footage is watched and labeled according to its content.
If a video has a high shooting ratio, it can be impractical to remember exactly where each shot is on each source tape or source file. Finding a particular source shot by searching through hours of video during editing can be time consuming, as well as tie up expensive editing equipment and editors' time.
A solution widely employed in the professional industry is to log the content prior to editing. Loggers go through the source video material, labeling it according to its contents within the metadata. This data is then available during editing, making the editing more efficient.
Software based logging systems allow clip lists to be imported directly into computer based editing systems.
Free-to-Air and Subscription broadcasters often have a statutory requirement to keep a record of all programs that are emitted. This may be for legal or other compliance purposes—or simply good commercial sense to 'have proof' of events in event of a contrary claim.
Traditionally, compliance recordings were made to long-play video-cassette decks, using three 8-hour tapes per day per channel. The unreliability of moving tapes and heads, along with the move to central casting and distributed playback requirements, has made this method virtually impossible to maintain in the current operational climate.
Larger multi-channel broadcasters with hundreds of feeds running simultaneously could potentially use several thousand VHS decks in rotation, along with the equipment racking, tape storage space and staff to manipulate those assets—and tens of thousands of tapes required to span the compliance retention period.
Developments since the early 2000s have shifted to multi-channel server-based rich-media logging, with a few brave souls using domestic PVR software to achieve the basic functionality at a reduced cost.
Since 2005, more advanced systems such as the Actus Digital Intelligent Monitoring Platform were introduced and provide data sync to broadcast automation systems, as well as alerts on basic signal status, event logging for review of non program related events which may have been visible on air, and notification of non-compliance with federal regulations such as requirement to broadcast Closed Captions and CALM Act Compliance.
In addition to logging to disk, some packages also provide live streaming for internal use, or to be repurposed to external web or news sites.
A variety of disk-based compliance logging packages suitable for a range of customer applications are available— each employing a number of proprietary methods and technologies.
DV refers to a family of codecs and tape formats used for storing digital video, launched in 1995 by a consortium of video camera manufacturers led by Sony and Panasonic. In the late 1990s and early 2000s, DV was strongly associated with the transition from analog to digital desktop video production, and also with several enduring "prosumer" camera designs such as the Sony VX-1000. DV is sometimes referred to as MiniDV, which was the most popular tape format using a DV codec during this time.
RT-11 is a discontinued small, low-end, single-user real-time operating system for the full line of Digital Equipment Corporation PDP-11 16-bit computers. RT-11 was first implemented in 1970. It was widely used for real-time computing systems, process control, and data acquisition across all PDP-11s. It was also used for low-cost general-use computing.
Non-linear editing is a form of offline editing for audio, video, and image editing. In offline editing, the original content is not modified in the course of editing. In non-linear editing, edits are specified and modified by specialized software. A pointer-based playlist, effectively an edit decision list (EDL), for video and audio, or a directed acyclic graph for still images, is used to keep track of edits. Each time the edited audio, video, or image is rendered, played back, or accessed, it is reconstructed from the original source and the specified editing steps. Although this process is more computationally intensive than directly modifying the original content, changing the edits themselves can be almost instantaneous, and it prevents further generation loss as the audio, video, or image is edited.
Video editing is the manipulation and arrangement of video shots. Video editing is used to structure and present all video information, including films and television shows, video advertisements and video essays. Video editing has been dramatically democratized in recent years by editing software available for personal computers. Editing video can be difficult and tedious, so several technologies have been produced to aid people in this task. Pen based video editing software was developed in order to give people a more intuitive and fast way to edit video.
A hard disk recorder (HDR) is a system that uses a high-capacity hard disk to record digital audio or digital video. Hard disk recording systems represent an alternative to reel-to-reel audio tape recording and video tape recorders, and provide non-linear editing capabilities unavailable using tape recorders. Audio HDR systems, which can be standalone or computer-based, are typically combined with provisions for digital mixing and processing of the audio signal to produce a digital audio workstation (DAW).
A digital video recorder (DVR) is an electronic device that records video in a digital format to a disk drive, USB flash drive, SD memory card, SSD or other local or networked mass storage device. The term includes set-top boxes with direct to disk recording, portable media players and TV gateways with recording capability, and digital camcorders. Personal computers are often connected to video capture devices and used as DVRs; in such cases the application software used to record video is an integral part of the DVR. Many DVRs are classified as consumer electronic devices; such devices may alternatively be referred to as personal video recorders (PVRs), particularly in Canada. Similar small devices with built-in displays and SSD support may be used for professional film or video production, as these recorders often do not have the limitations that built-in recorders in cameras have, offering wider codec support, the removal of recording time limitations and higher bitrates.
Betacam is a family of half-inch professional videocassette products developed by Sony in 1982. In colloquial use, "Betacam" singly is often used to refer to a Betacam camcorder, a Betacam tape, a Betacam video recorder or the format itself.
A broadcast flag is a bit field sent in the data stream of a digital television program that indicates whether or not the data stream can be recorded, or if there are any restrictions on recorded content. Possible restrictions include the inability to save an unencrypted digital program to a hard disk or other non-volatile storage, inability to make secondary copies of recorded content, forceful reduction of quality when recording, and inability to skip over commercials.
A digital audio workstation (DAW) is an electronic device or application software used for recording, editing and producing audio files. DAWs come in a wide variety of configurations from a single software program on a laptop, to an integrated stand-alone unit, all the way to a highly complex configuration of numerous components controlled by a central computer. Regardless of configuration, modern DAWs have a central interface that allows the user to alter and mix multiple recordings and tracks into a final produced piece.
Digital obsolescence is the risk of data loss because of inabilities to access digital assets, due to the hardware or software required for information retrieval being repeatedly replaced by newer devices and systems, resulting in increasingly incompatible formats. While the threat of an eventual "digital dark age" was initially met with little concern until the 1990s, modern digital preservation efforts in the information and archival fields have implemented protocols and strategies such as data migration and technical audits, while the salvage and emulation of antiquated hardware and software address digital obsolescence to limit the potential damage to long-term information access.
Broadcast automation incorporates the use of broadcast programming technology to automate broadcasting operations. Used either at a broadcast network, radio station or a television station, it can run a facility in the absence of a human operator. They can also run in a live assist mode when there are on-air personnel present at the master control, television studio or control room.
HDV is a format for recording of high-definition video on DV videocassette tape. The format was originally developed by JVC and supported by Sony, Canon, and Sharp. The four companies formed the HDV Consortium in September 2003.
A DVD recorder is an optical disc recorder that uses optical disc recording technologies to digitally record analog or digital signals onto blank writable DVD media. Such devices are available as either installable drives for computers or as standalone components for use in television studios or home theater systems.
P2 is a professional digital recording solid-state memory storage media format introduced by Panasonic in 2004. The P2 card is essentially a RAID of Secure Digital (SD) memory cards with an LSI controller tightly packaged in a die-cast PC Card enclosure. The system includes cameras, decks as drop-in replacements for videotape decks, and a special 5.25-inch computer drive for random-access integration with non-linear editing systems (NLE). The cards can also be used directly where a PC card (PCMCIA) slot is available, as in most older notebook computers, as a normal hard disk drive, although a custom software driver must first be loaded.
In broadcasting, channel playout is the generation of the source signal of a radio or television channel produced by a broadcaster, coupled with the transmission of this signal for primary distribution or direct-to-audience distribution via any network. Such radio or television distribution networks include terrestrial broadcasting, cable networks, satellites, IPTV, OTT Video, point-to-point transport over managed networks or the public Internet, etc.
Blackbird is an integrated internet video platform, video editing software, covering non-linear editing and publishing for broadcast, web and mobile.
The term Harding test is generically understood to mean an automatic test for photosensitive epilepsy (PSE) provocative image sequences in television content. This is properly known as a PSE test since the publication of the Digital Production Partnership (DPP) technical requirements and the DPP PSE Devices document updated in November 2018.
Content storage management (CSM) is a technique for the evolution of traditional media archive technology used by media companies and content owners to store and protect valuable file-based media assets. CSM solutions focus on active management of content and media assets regardless of format, type and source, interfaces between proprietary content source/destination devices and any format and type of commodity IT centric storage technology. These digital media files most often contain video but in rarer cases may be still pictures or sound. A CSM system may be directed manually but is more often directed by upper-level systems, which may include media asset management (MAM), automation, or traffic.
Multi-image is the now largely obsolete practice and business of using 35mm slides (diapositives) projected by single or multiple slide projectors onto one or more screens in synchronization with an audio voice-over or music track. Multi-image productions are also known as multi-image slide presentations, slide shows and diaporamas and are a specific form of multimedia or audio-visual production.
Channel in a box is the name given to an all-in-one playout device for broadcast television. Commonly based on a standard PC, it includes the ability to store content immediately required, add graphics, and deliver it to a transmission chain. Thus it provides an integrated, software playout platform.
