A term sometimes used to describe matching the resolution of a television system to the picture size and viewing distance (visual acuity); more often a term used to describe the matching or horizontal and vertical (and sometimes diagonal) resolutions. There is some evidence that the lowest resolution in a system (e.g., vertical resolution) can restrict the perception of higher resolutions in other directions. See also Square Pixels.
Industry:Software
Pictures that are coded by using information present only in the picture itself and without depending on information from other pictures. I-pictures provide a mechanism for random access into the compressed video data. I-pictures employ transform coding of the pixel blocks and provide only moderate compression.
Industry:Software
Edit in which a scene already recorded on the master is continued with no apparent interruption. A match-frame edit is done by setting the record and source in-points equal to their respective outpoints for the scene that is to be extended.
Industry:Software
Compression that works entirely within one picture: also known as Spatial Coding.
Industry:Software
Each material has a number of attributes such as transparency, ambient, diffusion, refraction, reflection, and so on.
Industry:Software
Cinematographer, designer, teacher, consultant, and author who came up with the six priorities of electronic cinematography: Harry Mathias’ Priorities for Electronic Cimenatography (in order of importance) 1. Practicality, Flexibility, and Ruggedness 2. Aspect Ratio 3. Sensitivity 4. Gamma or Transfer Characteristic 5. Resolution 6. Standards Acceptance (or Standards Conversion)
Industry:Software
A form of compression in which the codec compresses the data within one frame relative only to itself. Key frames are compressed with intraframe compression because they must reconstruct an entire image without reference to other frames. See Delta Frame, Key Frame. Compare Interframe Compression.
Industry:Software
A) Device that converts the RGB components from the camera into colour difference signals and the reverse. b) A set of crosspoints in a particular functional area of a switcher corresponding to a bus (the controls for that matrix). See Audio Matrix and Primary Matrix.
Industry:Software
A still image or photo video compression standard. JPEG compression ratios vary from 20:1 to 40:1 with a lossless ratio of 5:1. JPEG is a symmetrical standard inasmuch as it takes the same amount of time to decompress as it does to compress video.
JPEG works best with smooth transitions and little motion.
