You can change effects in After Effects primarily by using the Effect Controls panel, the Timeline panel, or by manipulating effect control points directly in the Layer or Composition panels.
Here's a breakdown of how to modify effect properties within After Effects:
Accessing and Modifying Effect Properties
There are several ways to access and change effect settings:
-
Effect Controls Panel: This panel is usually docked at the top left of your screen. It displays all applied effects and their properties for the selected layer. You can directly adjust values, use sliders, and change settings in this panel.
-
Timeline Panel: Expand the layer in the Timeline panel. Then, twirl down the "Effects" property. You'll see a list of all applied effects and their adjustable properties.
-
Layer/Composition Panel Manipulation: Some effects allow you to directly manipulate their control points within the Layer or Composition panels. For example, the Beam effect has start and end points that can be moved directly on the layer itself.
Steps for Changing Effects:
-
Select the Layer: Click on the layer in the Timeline panel to which the effect is applied.
-
Open the Effect Controls Panel: If it's not already open, go to Window > Effect Controls.
-
Locate the Effect: In the Effect Controls panel (or by expanding the layer in the Timeline), find the effect you want to modify.
-
Adjust Properties:
- Numerical values: Click and drag the numbers, type in new values, or use the up/down arrows to increment or decrement.
- Sliders: Click and drag the slider to change the value.
- Checkboxes: Enable or disable options by clicking the checkbox.
- Drop-down menus: Select a new option from the menu.
- Color pickers: Choose a new color from the color picker window.
-
Keyframing (Optional): To animate the effect over time, click the stopwatch icon next to a property to add a keyframe. Then, move to a different point in time on the timeline and change the property value. After Effects will automatically interpolate the changes between the keyframes.
Applying Multiple Instances of the Same Effect
After Effects allows you to apply the same effect multiple times to a single layer. This can create complex and interesting results.
- Apply the effect to the layer as normal.
- Apply the same effect to the same layer again. After Effects will create a new instance of the effect.
- You can then adjust the properties of each instance independently.
- Rename instances: Right-click on an effect's name in the Effect Controls panel and choose "Rename" to give each instance a descriptive name. This makes it easier to keep track of them.
Example: Changing the Blur Amount
Let's say you've applied the Gaussian Blur effect:
- Select the layer with the Gaussian Blur effect.
- In the Effect Controls panel, find the "Blurriness" property.
- Click and drag the number next to "Blurriness" to increase or decrease the blur amount. You can also type a specific value.
- To animate the blur, click the stopwatch icon next to "Blurriness", move to a different point in time, and change the "Blurriness" value again.
