How to set keyframes in AE
In After Effects (AE), keyframes are the core element of animation production. Mastering the setting skills of keyframes allows you to easily create smooth animation effects. This article will introduce in detail the setting method of keyframes in AE, and provide you with a practical operation guide based on hot topics and hot content in the past 10 days.
1. Basic concepts of key frames
Keyframes are frames in animation that define attribute changes. By marking keyframes on the timeline, AE will automatically calculate changes in intermediate frames to generate smooth animation effects. Here are the basic steps for keyframing:
| Operation steps | Description |
|---|---|
| 1. Select layer | Select the layer to which you want to add keyframes in the Timeline panel. |
| 2. Expand properties | Click the small triangle on the left side of the layer to expand the layer's property list. |
| 3. Add keyframes | Click the stopwatch icon to the left of the attribute to activate the keyframe function, then move the playhead on the timeline, adjust the attribute value and add keyframes. |
| 4. Adjust keyframes | Adjust animation effects by dragging keyframes or modifying property values. |
2. Types of key frames
Keyframes in AE are divided into many types, and different types of keyframes can create different animation effects. The following are some common keyframe types:
| Keyframe type | Description |
|---|---|
| linear keyframe | The default type, the animation changes speed evenly. |
| Bezier keyframes | You can control the acceleration and deceleration effects of animation by adjusting the handle. |
| Freeze keyframe | The animation changes suddenly between keyframes with no transition effect. |
3. Advanced techniques of key frames
In addition to basic keyframe settings, AE also provides some advanced techniques to help you create more complex animation effects.
| Skills | Description |
|---|---|
| 1. Use the chart editor | The Graph Editor provides more precise control over the speed and easing of keyframes. |
| 2. Copy and paste keyframes | Keyframes can be copied to other properties or layers, saving time. |
| 3. Expression keyframes | Keyframes can be automatically generated through expressions to achieve complex animation effects. |
4. Combination of hot topics in the past 10 days and AE key frames
