SpeedSix.RemGrain2 (Discreet Box2)
PURPOSE
Grain removal; a different and in most cases a better algorithm than the original RemGrain. RemGrain2 works by first calculating a map of where edges are in the input image. It then creates separately blurred versions of the red, green and blue channels. You control how much they are blurred. It then blends between the original image and the blurred image using the edge map. You get the original (sharp) image where there are edges (and hence real detail) and the blurred image where there are no edges - which kills off the film grain. You can weight the process towards preserving sharpness in edge regions while possibly keeping some unwanted grain, or killing grain at the possible cost of blurring genuinely important image detail. This is the purpose of the sharpness controls.
INPUT CLIPS
1: Input
RemGrain2 CONTROL PAGE
RGB (List Box Options: Mix | Exclusive, Default: Mix)
Work with a mixture of the rgb channels or each one exclusively. After tuning each channel switch back to Mix mode to reveal the completed grain removal.
Pos2 (Position Default: 0.6,0.6)
Pos1 (Position Default: 0.4,0.4)
ROI box (Checkbox Default: Off)
Switch on to examine a particular area, leaving pixels outside unaffected.
R (Checkbox Default: On)
G (Checkbox Default: On)
B (Checkbox Default: On)
In Mix mode all channels are active initally though you can toggle them on and off to see the resultant colour component. In Exclusive mode the grey level of each channel is displayed so you can work on perfecting the settings for the channel chosen.
R (Checkbox Default: On)
See also: G, B
View only the red channel - in both Mix and Exclusive modes.
G (Checkbox Default: Off)
See also: R, B
View only the green channel - in both Mix and Exclusive modes.
B (Checkbox Default: Off)
See also: R, G
View only the blue channel - in both Mix and Exclusive modes.
Red Blur (Number Min: 0.0, Max: 100.0, Default: 5.0)
Green Blur (Number Min: 0.0, Max: 100.0, Default: 5.0)
Blue Blur (Number Min: 0.0, Max: 100.0, Default: 5.0)
Gently blur each channel to even out the grain and then......
Red Sharp (Number Min: 0.0, Max: 100.0, Default: 1.0)
Green Sharp (Number Min: 0.0, Max: 100.0, Default: 1.0)
Blue Sharp (Number Min: 0.0, Max: 100.0, Default: 1.0)
......set the sharpening level for each channel to bring back into focus.
Hint: The default sharpness is usually too low. Try working down from the
maximum to get the best results.
