— Saturation: This slider controls the scale between a grayscale and color noise pattern. A value of
0.000 is completely grayscale, and a value of 1.000 is fully color.
— Color Tint: Sets the overall color of the effect.
— Invert Dark Regions: Check this box to invert the dark regions to white and darken the edges in the noise pattern.
— Invert Pattern: Check this box to invert the color of the noise.
— Allow Negative Values: Check this box to apply negative values to the Output section below.
Position
Controls that adjust the center and direction of the noise pattern.
— Position X/Y: Location of the center of the noise pattern.
— Rotation: Rotates the noise pattern around its center.
— Position Reference: Controls how to position the effect when a clip is re-sized or moved in the Timeline.
— Sizing and FX Tracker: The noise pattern follows Sizing and FX Tracker adjustments in the Color page. For example, if you used the FX Tracker to track a camera pan, the noise pattern would move with the pan, rather than stay in one place as the shot panned underneath it.
— Keyframed Positions: The noise pattern position can be adjusted as normal using keyframes.
The position and rotation controls can also be adjusted directly in the Viewer when the Open FX Overlay mode is selected from the drop-down menu in the bottom left of the Viewer. Dragging the star in the Viewer adjusts the X/Y position. Dragging the circle clockwise or counterclockwise sets the rotation.
Auto-Animation
These controls allow you to adjust the animation of the noise pattern.
— Velocity X/Y: How far to automatically advance each frame from the start position. You can keyframe these controls to change the noise pattern’s direction, without adjusting its actual X/Y position. This lets you mimic motions like smoke changing direction in the wind.
— Seethe: Controls how far to automatically evolve each frame from the starting Evolution value.
— Randomize Start Frame: Aligns the skipping cycle to the current frame. This allows you to re-use a favorite effect in multiple clips without it looking exactly identical in each instance.
— Start Frame: Lets you set the reference frame for the skip pattern. This allows you to control the sequence of noise you get, just in case you need to match it to the same noise pattern on another clip. This frame will be repeated.
Output
These controls allow you to choose how to adjust the output of the noise pattern.
— Preview Noise: Checking this box shows the noise pattern alone.
