DVO Grain

Digital Vision DVO Grain algorithm is specifically designed to manage the look

of film grain and to reduce unwanted electronic noise in film or video

originated material. Uses include restoration, compression pre-processing,

and image processing of new feature film, television and commercial

material.

The Grain algorithm incorporates the Digital Vision Emmy award-winning

PHAME advanced motion estimation technology along with edge-preserving

3-D spatio-temporal filters and temporal (recursive) filters to allow artists to

produce clean, sharp pictures and to match the look of film grain from shot-to-

shot (including grain matching for underexposed film). The process of

adaptively selecting the best mix of spatial and recursive filtering for each pixel

is unique to the DVO Grain algorithm.

This effect has four groups of parameters:

The Enable toggle button allows the complete effect

to be turned on or off.

Basic mode - basic settings for a quick de-

grain

Processing - specific processing options

Key - keyed settings for chroma adaptation

Setup - settings for various processing

selections

Basic Settings and Presets

The DVO Grain Basic mode provides simple control of the grain/noise

reduction without sacrificing performance. Basic mode is a good starting

point before using the more advanced settings in the Processing and Setup

tabs (if necessary).
