The Digital Fact Book - Quantel

CineAltaSony brand for products designed for the digital cinematography market.See also: HDCAMCineon (file)An RGB bitmap file format (extension .cin) developed by Kodak and widely used for storingand transferring digitized film images. It accommodates a range of film frame sizesand includes up to full Vista Vision. In all cases the digital pictures have square pixelsand use 10-bit log sampling. The sampling is scaled so that each of the code values from0-1023 represents a density difference of 0.002 – describing a total density range of2.046, equivalent to an exposure range of around 2,570:1 or about 11.3 stops. Note thatthis is beyond the range of current negative film.The format was partly designed to hold virtually all the useful information contained innegatives and so create a useful ‘digital negative’ suitable as a source for post productionprocessing and creating a digital master of a whole program.See also: 10-bit log, DPXCClipThe name is taken from the film industry and refers to a segment of sequential frames madeduring the filming of a scene. In television terms a clip is the same but represents a segmentof sequential video frames. In Quantel editing systems, a clip can be a single video segmentor a series of video segments spliced together. A video clip can also be recorded with audioor have audio added to it.CloneAn exact copy, indistinguishable from the original. As in copying recorded material,eg copy of a non-compressed recording to another non-compressed recording. If attemptingto clone compressed material care must be taken not to decompress it as part of the processor the result will not be a clone.CodecOriginally short for a combination of a coder and decoder but now often used to describejust one or the other. Mostly codec refers to a compression coder or decoder such asJPEG, MPEG or JPEG 2000.Coded (video)See Composite39
