What happens when you toggle the animation tool?

When you toggle the animation tool, you enable the ability to manipulate clip properties over time. This feature allows you to create dynamic changes in various attributes such as position, scale, opacity, and more by setting keyframes. Keyframes mark specific points in time where a value changes, enabling you to animate those properties smoothly throughout the duration of the clip. This is a fundamental aspect of animation in video editing, as it allows for precise control over how elements are presented over time, making your projects more engaging and visually appealing.

The other options relate to different functionalities that the toggle animation tool does not provide. Disabling effects, adding keyframes automatically, or resetting audio levels are separate actions not directly associated with the toggling of the animation tool itself. The focus of the animation tool is specifically on creating and editing animations tied to properties of clips.
