Overview
Film Grain creates an auto-animated noise effect designed to simulate the appearance of grain particles in the emulsion of movie or photo film.
Function
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 Browser™.
BCC filters also include common controls that configure global effect preferences and other host-specific effect settings.

Compare Mode
The BCC Compare Mode provides a convenient mechanism to compare the effect result with the original source layer. It provides several variations on basic split-screen views with the filtered clip placed next to the unedited original.

**CompareModepop-up:**Controls what is displayed by the Compare Mode. The options are:
- Offshows the output of the filter.
- Side BySidethe left side of the output shows half of the incoming image, and the right side shows the same half of the image as processed by the filter. When in Side-by-Side mode, the corresponding Slide and Right Offset sliders become available.Wipeenables the user to interactively wipe the effect across the image. The left side of the wipe bar on the image output shows the unfiltered image, while the right side of the wipe bar shows the filtered result. When in Wipe mode, the corresponding Wipe slider becomes available.
- Wipe/Slideoperates as a Wipe function when Wipe is selected in Compare Mode, and as a Slide function when Side-‐By-‐Side is selected in Compare Mode. When in Wipe mode, adjustments to this parameter moves the vertical wipe bar across the image; the region on the left of the wipe bar shows the original unfiltered image, while the region on the right shows the filtered result. When in Slide mode, adjustments to this parameter pans the image in the viewer window, maintaining the spatial relationship in the viewer between the before and after images.
- Right**Offsetprovides a way to adjust the spatial relationship between the unfiltered original image and the filtered result in the viewer window. Adjustments to this parameter will offset the position of the filtered image in the viewer.
When the Monochromatic****checkboxis selected, the RedAmount, GreenAmount, and Blue Amountsettings add luma noise to each color channel, creating a grayscale grain effect. When this checkbox is deselected, the Amount settings add colored noise to each color channel.

- Note: For the most realistic film grain effects, select Monochromatic for grayscale images, and deselect this option when working with color footage.
RedAmount, GreenAmount, and Blue****Amountadjust the amount of grain added to each respective color channel.

| Red Amount=50 | Red Amount=100 |
RedGrainSiz****e, GreenGrainSiz****e, and BlueGrainSizeset the size of the grains in each respective color channel.
The BlurQualitymenucontrols the quality of the post blur applied to the grain in all three channels. Pyramidis the fastest option and is generally adequate. It produces a blur similar in quality to the Pyramid Blur filter. Pyramid**Smootherproduces a better quality pyramid blur and increases rendering times slightly***.The remaining choices, *GaussianLow*, *GaussianMedium*, *GaussianHigh,GaussianHigher*, and *Gaussian*Highest*produce gaussian blurs of increasing quality. These options increase rendering times proportionately.
Random****Seeddetermines 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 grain pattern.
Select the AutoAnimatecheckboxto create an animated effect in which the configuration of the grain pattern changes throughout the duration of the effect. Deselect this option to manually animate the effect, or to create a static effect.
Select the FilmTintOncheckboxto use the chosen FilmTint****Colorto tint the image.
TintAmountadjusts the amount of the Film Tint Color that is applied to the image. At a value of 0, the Film Tint Color has no affect. At a Tint Amount value of 100, the image is fully tinted with the selected color. Intermediate values produce a partially tinted image.

Motion Tracker
The BCC Motion Tracker allows you to track the motion of an object, then use the motion path to drive other geometric properties of the effect without the need for keyframing.

PixelChooser
The BCC PixelChooser provides simple, built-in masking of the effect result. The PixelChooser is generally used to select a portion of the image and restrict an effect to just the selected area while maintaining the original image content in unselected regions. The selection can be based on geometric shapes or on the image’s luma/color properties.
