Video Tap
A video tap is an accessory for a motion picture camera used in filmmaking to provide a video signal from the camera lens. Video taps are used to allow the film crew to see what is in the camera's frame without having to look through the viewfinder, as well as allowing video to be recorded and can be used to create an immediate rough cut, if needed. Since a video tap normally attaches to a camera's existing viewfinder using a beam splitter, the video appears dark and frame rate flicker is visible. Sometimes the tap will include frame lines and burned in timecode and keykode Keykode (also written as either KeyKode or KeyCode) is an Eastman Kodak Company advancement on edge numbers, which are letters, numbers and symbols placed at regular intervals along the edge of 35 mm and 16 mm film to allow for frame-by-fram .... The person who operates a video tap is sometimes called a "video assist". Video taps can be useful for the director of a production to ensure the shot is to thei ...

Motion Picture Camera
A movie camera (also known as a film camera and cine-camera) is a type of photographic camera that rapidly takes a sequence of photographs, either onto film stock or an image sensor, in order to produce a moving image to display on a screen. In contrast to the still camera, which captures a single image at a time, the movie camera takes a series of images by way of an intermittent mechanism or by electronic means; each image is a ''frame'' of film or video. The frames are projected through a movie projector or a video projector at a specific frame rate (number of frames per second) to show the moving picture. When projected at a high enough frame rate (24 frames per second or more), the persistence of vision allows the eyes and brain of the viewer to merge the separate frames into a continuous moving picture. History A forerunner to the movie camera was the machine invented by Francis Ronalds at the Kew Observatory in 1845. A photosensitive surface was drawn slowly past the ape ...

Filmmaking
Filmmaking or film production is the process by which a Film, motion picture is produced. Filmmaking involves a number of complex and discrete stages, beginning with an initial story, idea, or commission. Production then continues through screenwriting, Casting (performing arts), casting, pre-production, Principal photography, shooting, Sound recording and reproduction, sound recording, post-production, and screening the finished product before an audience, which may result in a film release and exhibition. The process is nonlinear, in that the filmmaker typically shoots the script out of sequence, repeats shots as needed, and puts them together through editing later. Filmmaking occurs in a variety of economic, social, and political contexts around the world, and uses a variety of technologies and cinematic techniques to make theatrical films, episodic films for television and streaming platforms, music videos, and promotional and educational films. Although filmmaking originally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Film Crew
A film crew is a group of people, hired by a production company, for the purpose of Filmmaking, producing a film or motion picture. The crew is distinguished from the Ensemble cast, cast, as the cast are understood to be the actors who appear in front of the camera or Voice acting, provide voices for characters in the film. The crew is also separate from the Film producer, producers, as the producers are the ones who own a portion of either the film studio or the film's Intellectual property#Rights, intellectual property rights. A film crew is divided into different departments, each of which specializes in a specific aspect of the Filmmaking#Production, production. Film crew positions have evolved over the years, spurred by technological change, but many traditional jobs date from the early 20th century and are common across jurisdictions and filmmaking cultures. Motion picture projects have three discrete stages: development, production, and distribution. Within the producti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viewfinder
In photography, a viewfinder is a device on a camera that a photographer uses to determine exactly where the camera is pointed, and approximately how much of that view will be photographed. A viewfinder can be mechanical (indicating only direction and approximate view), with simple optical components, with precision optics and optical functions, or a digital accessory device used with digital cameras. View camera, View camera These cameras had no separate viewfinder. The exact image (although upside-down and reversed left-right) was viewed on a ground glass installed either in a replaceable plateholder, or in a spring back where springs hold the ground glass at the focus plane until a photographic plateholder is slid in front of it. Spring backs usually had a flip-up cover protecting the ground glass. A black focusing cloth was used with larger models. Mechanical finders Later referred to as "sports finders", for many sports and newspaper applications optical viewfinders ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rough Cut
In filmmaking, the rough cut (also known as the first cut or editor's 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. The rough cut is the first stage in which the film begins to resemble its final product. Rough cuts are recognizable as a conventional film, but may have notable errors or defects, may not have the desired narrative flow from scene to scene, may lack soundtrack music, sound effects or visual effects, and still undergo many significant changes before the release of the film.

Beam Splitter
A beam splitter or beamsplitter is an optical instrument, optical device that splits a beam of light into a transmitted and a reflected beam. It is a crucial part of many optical experimental and measurement systems, such as Interferometry, interferometers, also finding widespread application in fibre optic telecommunications. Designs In its most common form, a cube, a beam splitter is made from two triangular glass prism (optics), prisms which are glued together at their base using polyester, epoxy, or urethane-based adhesives. (Before these synthetic resins, natural ones were used, e.g. Canada balsam.) The thickness of the resin layer is adjusted such that (for a certain wavelength) half of the light incident through one "port" (i.e., face of the cube) is reflection (physics), reflected and the other half is transmitted due to Total internal reflection#Frustrated_TIR, FTIR (frustrated total internal reflection). polarizer, Polarizing beam splitters, such as the Wollaston prism ...

Frame Rate
Frame rate, most commonly expressed in frame/s, or FPS, is typically the frequency (rate) at which consecutive images (Film frame, frames) are captured or displayed. This definition applies to film and video cameras, computer animation, and motion capture systems. In these contexts, frame rate may be used interchangeably with and refresh rate, which are expressed in hertz. Additionally, in the context of computer graphics performance, FPS is the rate at which a system, particularly a GPU, is able to generate frames, and refresh rate is the frequency at which a display shows completed frames. In electronic camera specifications frame rate refers to the maximum possible rate frames could be captured, but in practice, other settings (such as exposure time) may reduce the actual frequency to a lower number than the frame rate. Human vision The temporal sensitivity and resolution of human vision varies depending on the type and characteristics of visual stimulus, and it differs betw ...

Timecode
A timecode (alternatively, time code) is a sequence of numeric codes generated at regular intervals by a timing synchronization system. Timecode is used in video production, show control and other applications which require temporal coordination or logging of recording or actions. Video and film In video production and filmmaking, SMPTE timecode is used extensively for synchronization, and for logging and identifying material in recorded media. During filmmaking or video production shoot, the camera assistant will typically log the start and end timecodes of shots, and the data generated will be sent on to the editorial department for use in referencing those shots. This shot-logging process was traditionally done by hand using pen and paper, but is now typically done using shot-logging software running on a laptop computer that is connected to the timecode generator or the camera itself. The SMPTE family of timecodes are almost universally used in film, video and audio pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keykode
Keykode (also written as either KeyKode or KeyCode) is an Eastman Kodak Company advancement on edge numbers, which are letters, numbers and symbols placed at regular intervals along the edge of 35 mm and 16 mm film to allow for frame-by-frame specific identification. It was introduced in 1990. Keykode is a variation of timecode used in the post-production process which is designed to uniquely identify film frames in a film stock. Edge numbers Edge numbers (also called key numbers or footage numbers) are a series of numbers with key lettering printed along the edge of a 35 mm negative at intervals of one foot (16 frames or 64 perforations) and on a 16 mm negative at intervals of six inches (twenty frames). The numbers are placed on the negative at the time of manufacturing by one of two methods: :''Latent image'' exposes the edge of the film while it passes through the perforation machine. This method is primarily used for color negative films. :''Visible ink'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Video Assist
Video assist is a system used in filmmaking that allows filmmakers to view and distribute a video version of a take immediately after it is filmed. On set, the location where the assist is reviewed is called a ''video village''. Usage Originally developed to show the camera's view to more people than the one looking through the eyepiece, today video assist is the name of a complex system, consisting of monitors, recorders, video transmitters, video switchers, IT and RF equipment, and hundreds of yards of cables. The video assist crew—the video assist operator, assistant operator, cable guy and video trainee—are in charge of moving, plugging in cables, and troubleshoot. The whole system can easily fill a medium-sized truck. Their job is to set up the video village, consisting of the central video cart and accessories, and in the same or separate villages: director's monitors, producer's monitors, and sometimes DP's monitors (however that nowadays usually done by the DIT).
