Video Tutorial: Add custom animations to your Figma banner designs

To update a custom animation that you've previously saved, choose the animation you'd like to update from the Your Saved Animations select box; this will load up your saved animation and its keyframes into the custom animation panel.

Once you've chosen the saved animation, you can edit your keyframes and properties as needed. Once you're happy with the updates, click the Update Saved Animations button to save the changes and override the previous animation keyframes.

Please note, updating a saved animation will automatically apply the updated keyframes to any layers in your banners that was already using the custom animation you've just updated.
