DaVinci Resolve is a high-end colour grading application that is used to correct and enhance the colour of film and video. It has been used to colour grade more feature films and TV spots than any other system and is considered to be the benchmark or gold standard upon which all systems are measured. It also includes non-linear editing and basic digital audio workstation functionality.
