Question

These things are divided into four zones by concentric 128-faced polyhedra in the Primatte (“PRY-mat”) plug-in used by tools like The Foundry’s NUKE. These things are graphically represented by “scopes” like the waveform scope, the vectorscope, and a certain “parade”. These things are mapped (-5[1])to each other by 3D LUTs (“lutz”), or look-up tables, which are applied by software like DaVinci Resolve. A triangular region on a CIE 1931 diagram indicates (15[1])the possible (15[1])range of these things, which is called a (*) gamut. These things are encoded with phase or frequency modulation in incompatible regional standards like SECAM, PAL, and NTSC. In a technique called “keying”, (-5[1])one of these things is entirely removed from a video and replaced with a new background. For 10 points, name these things that are graded and corrected during film post-production, which might adjust their saturation. ■END■ (10[1]0[1])
