Keyframe Indices in After Effects #Shorts

In After Effects, there is a quick and efficient way to find the index value of any keyframe without manually counting each one from the beginning of your timeline. Manually counting can be time-consuming, especially if you have a large number of keyframes. Fortunately, there's a much faster method to achieve this.

Enable Keyframe Indices:
- Simply left-click on the icon that represents your keyframes.
- Click on "Use Keyframe Indices".
Instant Index Visualization:
- After enabling the keyframe indices, After Effects will immediately display the index value of each keyframe.
- For example, a keyframe might show as number 42.
Utilizing Indices in Expressions:
- You can now reference these index values in your expressions.
- For instance, to reference keyframe number 42, you would write an expression targeting this specific keyframe.
- You can then retrieve the value of this keyframe in your expression easily.
Reverting Back:
- At any time, you can switch back to the regular keyframe icons if you prefer the standard view.

Here's a practical example:

Suppose you have a keyframe at index 42 with a rotation value of -70. By using the keyframe indices method, the expression can target keyframe 42 and retrieve its value directly, confirming that the value is indeed -70.

This feature is particularly useful when working with complex animations and writing expressions, as it significantly simplifies the process of identifying and referencing keyframes.
