BCC Alpha Pixel Noise
Category: OBSOLETE
Effect Name: BCC Alpha Pixel Noise
Note: The BCC Alpha Pixel Noise filter has been depricated. Similar effects can be created using BCC+ Grain to add film quality noise and grain to an image.
The BCC Alpha Pixel Noise filter, part of the BCC Obsolete category, adds noise to an imageโs alpha channel. It can be used to create pixelated transitions between two images.
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 Browserโข.
- 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.
- Alpha Offset:Adds or subtracts a fixed value to the alpha channel for each pixel affected by the noise. Set Alpha Offset to โ255 and Noise to 0 to make each affected pixel completely transparent, or Alpha Offset to 255 and Noise to 0 to make each affected pixel completely opaque. .
- Noise:Sets the amount of noise applied to each affected pixel.
- Action:Determines how the alpha channel is altered in each affected pixel.
- Transparency: Decreases opacity in the affected pixels. Choose Increase Transparency if the source image is completely opaque.
- Opacity: Increases opacity in the affected pixels. Choose Increase Opacity if the source image is fully transparent.
- Both: Increases opacity in affected pixels that are transparent and decreases opacity in affected pixels that are opaque. Choose Both if the source image contains both transparent and opaque regions.
- Random Seed:Determines the value input to the random number generator used by the filter. Animating Random Seed 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.
- Perturbation:Adds a small amount of randomness to the numbers produced by Random Seed.
- Perturbation Seed:Adds additional randomness to the numbers produced by Random Seed.
