UM:Dvo Effects Dvo RegrainRGB
DVO Regrain RGB allows you to quickly set up and generate natural looking film grain. You can match almost any type of film stock by setting the grain size and sharpness as well as matching the characteristics of highlight and lowlight intensity behavior in each individual colour channel.
The Enable button enables the entire effect :
This is the total amount of grain added and calculated as a percentage versus the grain texture setup.
Values | 0 - 4.0 |
Default | 1.0 (100%) |
Where to add the grain : RGB or single channels.
The BW options are for selecting the parameter channel to use for adjusting the grain texture.
Values | RGB, BW (Red), BW (Green), BW (Blue) |
Default | RGB |
How saturated the grain should be.
This applies to RGB colour mode.
Define the grain applied for each channel in RGB.
In BW we use the setup per the channel selected in the global Colour setup above.
Define the size of the grain created (per channel).
Values | 1.0 - 4.0 |
Default | 1.6 |
Define the sharpness of the grain created (per channel).
Values | 0.0 - 1.0 |
Default | 0.5 |
If enabled, generated grain will be same in low (dark) and high (bright) lights.
Default | Enabled |
- If Uniform (Amount) is enabled, this sets the total amount of grain generated.
- If Uniform (Amount) is disabled, this sets the total amount of grain generated in Low lights only.
Values | 0.0 - 4.0 |
Default | 1.0 |
Specifies the amount of film grain to be added in high lights (per channel).
Values | 0.0 - 4.0 |
Default | 1.0 |
Midpoint Balance controls the amount of the frequency range considered to be highlight and lowlight, and thus affects how the highlight and lowlight amounts are applied.
Values | -1.0 - +1.0 |
Default | 1.0 |
Note:
- To treat more of the spectrum as highlight, enter a negative number.
- To treat more of the spectrum as lowlight, enter a positive number.
- If "0" is used, the gradual change between lowlight and highlight is completely linear.
