What is Keyframing in After Effects?
Working with the frames to organize and control the content of the document. You place frames in the sequences you want the objects in the frames to appear from start to end of the content
Keyframe in Animation
In animation, a keyframe is a drawing that defines the starting and ending points of smooth transition. A sequence of keyframes defines which movement the viewer sees first, whereas the position of the keyframes on the animation defines the movement timing. Over a span of a second just two or three keyframes do not create the illusion of movement, all the remaining frames are filled within inbetweens.

Overview of Keyframe
As animations and videos are made up of frames, a keyframe is a mark (a diamond symbol in most cases) that is created at a specific time for one particular layer property’s value. It can be for the position (shortcut = P), scale (S), rotation (R), opacity (T), anchor point (A), or other properties in effects and plugins. At least two keyframes are used to create a change with a property’s value over time. One is placed at the opening of a move, and others at the ending with the new value.
1. Adding Keyframes
Select the layer property to create a new keyframe and click on the stopwatch then a keyframe will appear at the current time indicator on the selected property. Now the selected property is actively indicated by a blue stopwatch. When a layer property is active, any change you make in the layer value automatically creates a new keyframe with the change or adjusts the current keyframe.
When it is inactive, there are no keyframes, and any adjustments will keep the value the same for the entire duration of the layer. To create a keyframe without changing value, simply copy/paste the keyframe at a new position, or click on the grey keyframe navigation button (the grey diamond to the left of the layer).
2. Adjusting Keyframe Values
Whirl down the triangles next to the layer and transform properties. The blue numbers have every property’s values as well as the value of the keyframe at that time. You can click and drag left or right to increase or decrease the value, or you can click and manually type the value you want.
If you only see one value or property, you can hit shift + (property shortcut) to bring it up, in addition to the one you are seeing. View all your keyframes by clicking U and view all modified keyframes in your project by clicking U+U (twice).

3. Removing and Moving Keyframes
To remove a single keyframe – Select on it and delete, or select on it and click the blue keyframe navigation button and it will be removed.
To remove all keyframes – Click on the blue stopwatch, and all keyframe will be deleted.
You can move the keyframe left or right in the timeline by just clicking and dragging it to your chosen spot.
