The higher value the more noise is removed from gained shadows.Īverage luminance to which video should be gained. The lower value then less bright parts of image are gained (help for high values of gain).ĭefault 0.5, values from 0.0 to 2.0. Parameters for sublte white balance correction, shift_u 0 - removes yellow tint, shift_v 0 - removes green tint (default 0).Īuto correction, recommended values 0.8 - 1.0, default 0.0. Number of iterations for mode 0 (values from 1 to 9, default 4).Įvery luminance value x is shifted down by shift (x = x - shift), helpful in low-light, some camcorders brighten image by getting black more gray (default 0).ĭefault true - not only gain but also enhance shadows. 2 : plugin automatically choose between 0 (off) and 1 (on) - (default).
Maximum gain value which can't be passed by auto control. Syntax and Parameters HDRAGC (clip, float "max_gain", float "min_gain", float "coef_gain", float "max_sat", float "min_sat", float "coef_sat", int "avg_window", int "response", int "debug", int "mode", int "protect", int "passes", int "shift", bool "shadows", int "shift_u", int "shift_v", float "corrector", float "reducer", int "corrector_mode", int "avg_lum", float "black_clip", int "freezer") : AviSynth+ or AviSynth 2.5.8 or greater.Amount of gain is calculated automatically but you can also influence on it by parameters. It's "simply" gaining (brightening) dark areas of image without causing blow of highlights and is doing it by simulating the work of our eyes. High Dynamic Range Automatic Gain Control - this plugin increase dynamic range of video clips (enhance shadows).
