A cam (camrip or camming, deriving from camcorder ) is a bootleg recording of a film. Generally unlike the more common DVD rip or screener recording methods which involve the duplication of officially distributed media, cam versions are original clandestine recordings made in movie theaters.
The most common type of cam is produced by a theater patron who smuggles a compact digital camcorder into the theater by hiding it in their clothing or in a container such as a handbag or backpack. The filmer then records the movie using the camcorder as unobtrusively as possible. They may try to pick a seat as far back in the auditorium as possible to avoid the attention of other patrons (and to ensure proper framing of the screen) and/or choose sparsely attended showtimes. The filmer may also rely on cinema employees who will overlook infringement activity because of an existing friend or family relationship, collusion, bribery, or apathy to the law.
In an attempt to impede this practice (as well as curb the smuggling in of non-theater food), some establishments now ban customers from carrying bags or other containers into theaters. As an additional form of deterrent, theaters may equip ushers with night vision goggles to discreetly catch a bootlegger in the act of recording. [1] With the improvement in camera quality and storage space of smartphones, it is now somewhat more difficult to detect when a person is recording in a movie theater.
Cams produced in this way use the camera's microphone to record audio, which tends to produce a recording that sounds "muddy". In addition, the microphone may pick up ambient noises in the auditorium, such as the audience's response to the film (e.g. laughter, screaming) or disruptive noises (crying baby, mobile phone ring, people coughing, etc.). A camera situated in the audience area may record silhouettes of other audience members, especially those leaving the theater for the restroom or concession stand. [2] In the auditoria of older or poorly maintained theaters, other sounds such as air conditioning or sound from adjacent auditoria may also be audible. Quality may also suffer from frame rate conversion issues if there is a mismatch between the frame rate of the camera and the projection (usually 24 fps). In other cases, a tripod is used in the handicapped sections of an auditorium while plugging the jack in a hard-of-hearing device. [3] These recordings with better sound are called telesync.
Sometimes cam versions are made by projectionists themselves, either for home use or to distribute (with or without profit). This provides several advantages: first, the projection booth window has a central, unobstructed view of the screen. Second, the projectionist can bypass the built-in microphone and link the camcorder directly to the monitor output of the audio rack, resulting in a clear, well-separated stereo recording. This is known as Telesync. The projectionist can also alleviate the frame rate conversion problem described above by speeding the projector up from film's traditional 24 fps to 25 fps and then use a standard PAL video camera to record the film picture. These advantages come with a higher risk: a projectionist, if caught, will almost certainly be fired, and is more likely than the typical audience member to face legal prosecution.
Since 2001, many major motion pictures have been shipped to theaters with watermarks of unique patterns of tiny dots embedded throughout the film, known as Coded Anti-Piracy technology. If the cammer is unable to catch and blur all of these sequences, the studio can determine at which theater the cam was recorded.
The overall quality of cam bootlegs is highly dependent upon the choice of theater (and sometimes the individual screening), the quality of camera used, the skill of the operator in framing the screen and minimizing camera movement, and the method of encoding used before distribution. Cams are generally considered to be the lowest fidelity method for duplicating video and film content, somewhat behind Telesync and markedly worse than DVD rips or screeners. For newly released films, however, cams are often the first bootleg copies available. In the developing world, cam DVDs are often available from street vendors for prices equivalent to US$1–2 (PPP); worldwide, they are swapped or sold on Internet pirate sites.
Around the start of the millennium, many first time camera recordings originated from Malaysia, recognizable by the burn-in Malay subtitles. VCDs often appeared 2 to 3 days before the theatrical release. In some cases, they were even available online 3 months before release. Robert Krulwich sees two possibilities as the main reason for such early availability of these illicit recordings. Someone in Hollywood shows movies a couple of days before they show them in America, or some people get prints sent to them from people in the Californian movie business. [3]
Warez is a common computing and broader cultural term referring to pirated software that is distributed via the Internet. Warez is used most commonly as a noun, a plural form of ware, and is intended to be pronounced like the word wares. The circumvention of copy protection (cracking) is an essential step in generating warez, and based on this common mechanism, the software-focused definition has been extended to include other copyright-protected materials, including movies and games. The global array of warez groups has been referred to as "The Scene", deriving from its earlier description as "the warez scene". Distribution and trade of copyrighted works without payment of fees or royalties generally violates national and international copyright laws and agreements. The term warez covers supported as well as unsupported (abandonware) items, and legal prohibitions governing creation and distribution of warez cover both profit-driven and "enthusiast" generators and distributors of such items.
Frame rate, most commonly expressed in frame/s, frames per second or FPS, is typically the frequency (rate) at which consecutive images (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 frame frequency 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 may reduce the actual frequency to a lower number than the frame rate.
A movie theater or cinema, also known as a movie house, cinema hall, picture house, picture theater, the pictures, or simply theater, is a business that contains auditoriums for viewing films for public entertainment. Most are commercial operations catering to the general public, who attend by purchasing tickets.
A movie 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 to show the moving picture. When projected at a high enough frame rate, the persistence of vision allows the eyes and brain of the viewer to merge the separate frames into a continuous moving picture.
Slow motion is an effect in film-making whereby time appears to be slowed down. It was invented by the Austrian priest August Musger in the early 20th century. This can be accomplished through the use of high-speed cameras and then playing the footage produced by such cameras at a normal rate like 30 fps, or in post production through the use of software.
A movie projector is an opto-mechanical device for displaying motion picture film by projecting it onto a screen. Most of the optical and mechanical elements, except for the illumination and sound devices, are present in movie cameras. Modern movie projectors are specially built video projectors.
A telesync (TS) is a bootleg recording of a film recorded in a movie theater, often filmed using a professional camera on a tripod in the projection booth. The audio of a TS is captured with a direct connection to the sound source. If a direct connection from the sound source is not possible, sometimes the bootlegger will tape or conceal wireless microphones close to the speakers, as it is better than a mic on the camera. A TS can be considered a higher quality type of cam, that has the potential of better-quality audio and video.
A workprint is a rough version of a motion picture or television program, used by the film editor(s) during the editing process. Such copies generally contain original recorded sound that will later be re-dubbed, stock footage as placeholders for missing shots or special effects, and animation tests for in-production animated shots or sequences.
Coded anti-piracy (CAP) is an anti-copyright infringement technology which marks each film print of a motion picture with a distinguishing pattern of dots, used as a forensic identifier to identify the source of illegal copies.
A projectionist is a person who operates a movie projector, particularly as an employee of a movie theater. Projectionists are also known as "operators".
CineAlta cameras are a series of professional digital movie cameras produced by Sony that replicate many of the same features of 35mm film motion picture cameras.
The Sony HDR-HC1, introduced in mid-2005, is the first consumer HDV camcorder to support 1080i.
Pirated movie release types are the different types of pirated movies and television series that are shared on the Internet. The quality and popularity of pirated movie release types vary widely, due to the different sources and methods used for acquiring the video content, the development and adoption of encoding formats, and differing preferences on the part of suppliers and end users as to quality and size-efficiency.
A cue mark, also known as a cue dot, a cue blip, a changeover cue or simply a cue, is a visual indicator used with motion picture film prints, usually placed in the upper right corner of a film frame. Cue dots are also used as a visual form of signalling on television broadcasts.
A release print is a copy of a film that is provided to a movie theater for exhibition.
The term telecine refers both to a film-to-tape transferring machine, as well as the process by which film is transferred to tape. The telecine process is frequently used by filmmakers to transfer production footage to video, which can then be captured by various non-linear digital editing systems.
A digital movie camera for digital cinematography is a motion picture camera that captures footage digitally rather than physical film, known as film stock. Different digital movie cameras output a variety of different acquisition formats. Cameras designed for domestic use have also been used for low-budget independent productions.
The analog hole is a perceived fundamental and inevitable vulnerability in copy protection schemes for noninteractive works in digital formats which can be exploited to duplicate copy-protected works using analog means. Once digital information is converted to a human-perceptible (analog) form, it is a relatively simple matter to digitally recapture that analog reproduction in an unrestricted form, thereby fundamentally circumventing any and all restrictions placed on copyrighted digitally distributed work. Media publishers who use digital rights management (DRM), to restrict how a work can be used, perceive the necessity to make it visible or audible as a "hole" in the control that DRM otherwise affords them.
A projection booth, projection box or Bio box is a room or enclosure for the machinery required for the display of movies on a reflective screen, located high on the back wall of the presentation space. It is common in a movie theater.
