Industry Definitions

2K Generic term for data with a resolution of about 2000 pixels.

4K Generic term for data with a resolution of about 4000 pixels.

3D Generic term for images having a three-dimensional appearance.

4:2:2 A sampling ratio. For every 4 samples of luminance there are two samples each of R-Y (Red minus luminance)and B-Y (Blue minus luminance). It has full black and white resolution, but only half the colour information.

4:4:4 A sampling ratio that has equal amounts of the luminance and both chrominance channels.

ADR Automatic dialogue replacement.Also referred as "post sync dialogue".

Answer Print First film print produced by the laboratory from the original/digital negative and optical sound negative with approved picture grading and soundtrack.

Airline Version Picture (often censored for objectionable language, violence & sexual themes) that is available “in cabin” on an airline for all passengers to view.

Background plate A shot serving as background for other elements, typically for a visual effect; a placeholder for a shot.

Burn-in To encode information directly into an image.

Compositing Layering multiple images, typically for a visual effect.

Composite Print 35mm film print containing both picture and sound tracks.

Contrast Measurement of how far the whitest whites are from the blackest blacks.

Compression The process of making something smaller, either by discarding or re-organising data/information.

Conform The process of assembling source material in an edited form.

Dailies (Rushes) Camera image vision & production recorded sound synced, in a form (e.g. Quicktime file) ready for viewing.

Digital Dailies Internet based systems for streaming the dailies for viewing.

DCDM Digital Cinema Distribution Master is the uncompressed digital picture master (files) in reels produced from the conformed and graded picture data It is the digital cinema equivalent of the traditional 35mm DI negative.

DCP-OV Digital Cinema Package (Original Version) is the distribution master for digital cinema made by encoding (wrapping) the DCDM files and the printmastered sound (wav) files and encrypting them. It is the digital cinema equivalent of the traditional 35mm Internegative and 35mm Optical Sound Negative.

DCP Digital Cinema Package clone of the DCP-OV copied to firewire drive, which is sent to cinemas to load onto their servers. Often called the "digital print", it is equivalent to a traditional 35mm film print. However the cinema requires a KDM to be able to open (screen) the DCP.

Digital Cinema Theatrical projection at minimum 2K resolution of a digital image.

DI Traditionally the 35mm Digital Intermediate Negative of the Picture recorded from digital files. "DI" is also used as a term for the grading and completion stages for the digital cinema picture.

EDL Edit Decision List.

ESTAR Polyester base to film stoc.k

5.1 Six final digitally mixed tracks of the Picture to be played in surround sound.

FHA Full Height Anamorphic - full height and width of 16:9 video frame in a standard definition format.

FPS Frames per second.

Film-out The process/procedure of recording images from a digital source onto a film media (e.g. 35mm negative).

Frame rate The speed at which individual image frames are displayed to form a moving sequence, usually measured in Hertz or frames per second e.g. 24fps, 23.98psf

HD High Definition is a file resolution size (1080 or 720) and video tape format e.g. HD-SR or HDCAM.

KDM Key Delivery Message is a security key encryption system (file) that allows the DCP to play on a specific cinema playback server for a specific period of time. Each KDM is unique to the DCP and the server and cannot be transferred or used on any other server.

LUT Digital tape media used to archive data.

LUT Look-up table. A method for replacing stored colours with other colours, typically used to convert between different colour spaces.

Metadata Data information about the sound and vision. This includes digital and handwritten information.

MOD Magneto Optical Disc is a media format for audio digital data.

OAR Original Aspect Ratio in which the Picture was framed in camera and/or intended to be projected theatrically (in cinemas) or broadcast (on television)

On-Set Data Also "digital lab" where the camera original data is checked, transferred to a back-up drive and transcoded to a format able to be used in digital editing. The original data on the drive is then archived to LTO for storage.

OSTN 35mm Optical Soundtrack Negative produced from the audio digital files

Pan & Scan Re-framing images so that they appear full frame (without borders) in a TV Monitor.

Pillarbox Placing a full frame 4x3 image in a 16x9 aspect ratio video tape resulting in black vertical borders appearing on either side of the image.

QuickTime Software that comprises media (video, audio) as used on a computer network. Some QT codecs (programs) are Apple ProRes, H264, MP4.

Release Print Duplicate film prints made for general theatrical distribution.

Resolution The amount of detail in an image. Higher resolution equals more detail RGB (Red, Green, Blue)

Restore Extract data from LTO onto a digital network so it is accessible for use e.g.conform for picture completion

Scanning The process of digitally breaking down an image (e.g. 35mm film negative) into a series of elements representing light values and transmitting these elements into data.

Spools Also “Reels” of the of the Picture. Traditionally these were 35mm film each being 2,000 feet (22 minutes) maximum length for ease of handling but now can vary for digital cinema reels.

SD Standard definition video tape e.g. Digital Betacam; SP Betacam.

Stereoscopic Stereoscopic photography is the means by which 3D imagery is produced either in a motion picture camera system recording images from two side-by- side perspectives (that mimic the human eyes) or is created in post production using computer generated imagery.

Telecine The process of transferring film material to video on a machine.

Timecode A time reference in hours, minutes, seconds and frames, recorded digitally to identify each frame.

Tracklay The process of layering sound elements to create tracks which include dialogue, atmospheres, effects, foley, to build your sound track. From here, all elements are mixed together in the Final (sound) Mix.

Transcode Modifying image data to then encode into a different format.

VFX Visual Effects also called CGI (computer generated imagery).

Watermark A visible image, typically a logo, placed over images in a sequence to indicate ownership of the picture.
