Grain management

Controlling the amount of ‘film’ grain visible on a film or digital movie. Its appearance is considered by some to add a certain look to the production. Modern DI equipment can include grain management that can increase or decrease its visibility on film or digitally originated material. Aside from aesthetics, grain affects compression systems as they see it as extra movement and so can waste bandwidth by coding it – adding another reason for controlling the amount of grain according to the different coding requirements for, say, digital cinema and mobile reception.
