ScannedGrain_CB

This ScannedGrain has a smart tile system which allows you to triple the size of the source.  It has individual scaling.  It has the ability for you to save/store 4 grain presets.  You'll find both blur and sharpen enhancements for the grain.  There's a LUT color style range controls for setting film response low/mid/high.  You have the ability to use either the incoming alpha or the mask input, to mask the grain or apply grain everywhere.  I've included the ability to increase the density of the grain, in the less dense areas of the matte.  There is also a mix to decrease/increase the overall grain level.  There's also 2 additional tabs.  The first one is for boosting the brightness of the grain on the low end, useful when D.I. has gone too far and you still have to match.  The other is for working on undistorted plates.

Unique to this gizmo

- tile scanned grain (mirrored with time offsets to not show duplication)

- individual scale/filtering per channel

- option to use luminance and master controls or use separate RGB in the LUT range

- apply grain correctly to undistorted plates

- output grain, based off of input image

- mask red, green and blue individually with their own mattes

- increase the density of the grain, in the less dense areas of the alpha (falloff)

- create your own presets, in an external text file and load them, which can be set up differently for different projects as you can determine where it loads from
