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.
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.
Post-production is part of the process of filmmaking, video production, audio production, and photography. Post-production includes all stages of production occurring after principal photography or recording individual program segments.

Cinematography is the art of motion picture photography.
A hidden camera or spy camera is a camera used to photograph or record subjects, often people, without their knowledge. The camera may be considered "hidden" because it is not visible to the subject being filmed, or is disguised as another object. Hidden cameras are often considered a surveillance tool.
A camcorder is a self-contained portable electronic device with video and recording as its primary function. It is typically equipped with an articulating screen mounted on the left side, a belt to facilitate holding on the right side, hot-swappable battery facing towards the user, hot-swappable recording media, and an internally contained quiet optical zoom lens.

Stock photography is the supply of photographs that are often licensed for specific uses. The stock photo industry, which began to gain hold in the 1920s, has established models including traditional macrostock photography, midstock photography, and microstock photography. Conventional stock agencies charge from several hundred to several thousand US dollars per image, while microstock photography may sell for around US$0.25 cents. Professional stock photographers traditionally place their images with one or more stock agencies on a contractual basis, while stock agencies may accept the high-quality photos of amateur photographers through online submission.
Digital asset management (DAM) and the implementation of its use as a computer application is required in the collection of digital assets to ensure that the owner, and possibly their delegates, can perform operations on the data files.
Stock footage, and similarly, archive footage, library pictures, and file footage is film or video footage that can be used again in other films. Stock footage is beneficial to filmmakers as it saves shooting new material. A single piece of stock footage is called a "stock shot" or a "library shot". Stock footage may have appeared in previous productions but may also be outtakes or footage shot for previous productions and not used. Examples of stock footage that might be utilized are moving images of cities and landmarks, wildlife in their natural environments, and historical footage. Suppliers of stock footage may be either rights managed or royalty-free. Many websites offer direct downloads of clips in various formats.
Film-out is the process in the computer graphics, video production and filmmaking disciplines of transferring images or animation from videotape or digital files to a traditional film print. Film-out is a broad term that encompasses the conversion of frame rates, color correction, as well as the actual printing, also called scannior recording.
In filmmaking and video production, footage is raw, unedited material as originally filmed by a movie camera or recorded by a video camera, which typically must be edited to create a motion picture, video clip, television show or similar completed work.
Digital cinematography is the process of capturing (recording) a motion picture using digital image sensors rather than through film stock. As digital technology has improved in recent years, this practice has become dominant. Since the mid-2010s, most movies across the world are captured as well as distributed digitally.

In filmmaking, the rough cut is the second of three stages of offline editing. The term originates from the early days of filmmaking when film stock was physically cut and reassembled, but is still used to describe projects that are recorded and edited digitally.
A digital library is an online database of digital objects that can include text, still images, audio, video, digital documents, or other digital media formats or a library accessible through the internet. Objects can consist of digitized content like print or photographs, as well as originally produced digital content like word processor files or social media posts. In addition to storing content, digital libraries provide means for organizing, searching, and retrieving the content contained in the collection. Digital libraries can vary immensely in size and scope, and can be maintained by individuals or organizations. The digital content may be stored locally, or accessed remotely via computer networks. These information retrieval systems are able to exchange information with each other through interoperability and sustainability.
BBC Motion Gallery is the footage licensing division of BBC Studios. It offers creative professionals access to a collection of stock footage with licensing worldwide.
Reverse image search is a content-based image retrieval (CBIR) query technique that involves providing the CBIR system with a sample image that it will then base its search upon; in terms of information retrieval, the sample image is very useful. In particular, reverse image search is characterized by a lack of search terms. This effectively removes the need for a user to guess at keywords or terms that may or may not return a correct result. Reverse image search also allows users to discover content that is related to a specific sample image or the popularity of an image, and to discover manipulated versions and derivative works.
