BCC RGB Pixel Noise
Category: BCC Stylize
Effect Name: BCC RGB Pixel Noise
The BCC RGB Pixel Noise filter, part of the BCC Stylize category, applies noise to each of the RGB color channels independently. Alternately, the filter may be used to apply noise to the source imageβs luminance channel without changing the pixelsβ colors.
Working with the Filter
Presets and Common Controls
- BCC filters come with a library of factory installed presets plus the ability to create your own custom presets and preview them with the BCC FX Browserβ’.
- BCC filters also include common controls that configure global effect preferences and other host-specific effect settings.

Effect Controls
Mocha Mask and Track
Continuum effects include integrated masking and matte tools that allow you to restrict the effect to specific regions of the image.
- Mocha masks: used to create custom spline masks. Mocha also includes Matte Assist ML and Matte Refine ML, which use machine learning to generate and track masks.
- Pixel Chooser: used to generate geometric shapes, gradients, or mattes based on channel, luma, or color-based selections. Additionally, an AI depth map generator, and an AI-powered face detection model allow for precise control of masks and mattes.
Note: Mocha can also be used to drive geometric parameters. See the Mocha Motion Tracker documentation for details.
For more information, see Mocha and Pixel Chooser.
- Percentage: Sets the percentage of pixels affected by the noise.
- Luma Noise: Applies noise to the source imageβs luma channel without affect the source pixel colors. Leave this option deselected to apply noise to the RGB color channels.
- Red Noise, Green Noise, and Blue Noise: If Luma Noise is not selected, Red Noise, Green Noise, and Blue Noise control the amount of noise applied to the affected pixels in each respective color channel.
- Lock Noise Ratio: Determines the ratio between the amounts of noise in each channels is linked. If Red, Green, and Blue Noise are set to the same value, selecting Link Noise Ratio adds noise to the luminance channel. When the values are different, selecting this option adds bias, reducing the number of different colors appearing in affected pixels.
- Noise: If Luma Noise is selected, the Red Noise, Green Noise, Blue Noise, and Link Noise Ratio controls are replaced by a single Noise parameter which sets the amount of noise applied to each affected pixel.
- Clipping: When enabled, the noise and luminance values clip between 0 and 255. If this option is deselected, overflow creates a wrap, so that a pixel with a value of 256 wraps to 0, β1 wraps to 255, and so on. This creates a more incoherent look.
- Random Seed: Determines which value is input to the random number generator used by the filter. Adjust this value when you like the overall effect but want to adjust the random configuration of the noise pattern.
Note: Animating the Random Seed setting creates noise that varies from frame to frame, because the noise affects a different randomly chosen group of pixels in each consecutive frame. Keeping this setting at a constant value creates static noise that retains its appearance from frame to frame.
- Perturbation: Adds a small amount of randomness to the numbers produced by Random Seed, creating noise patterns that differs from frame to frame by a controlled amount.
- Perturbation Seed: Adds additional randomness to the perturbation parameter.
