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 to each other by 3D LUTs (“lutz”), or look-up tables, which are applied by software like DaVinci Resolve. (-5[1])A triangular region on a CIE 1931 diagram (15[1])indicates the possible range of these (15[1])things, (15[1])which is called a (*) gamut. (10[1])These things are encoded with phase or frequency modulation in incompatible regional standards like SECAM, PAL, and NTSC. In a technique called “keying”, 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■ (0[1])
