The Timeline is where you synchronize the animation of your objects.
The following video provides details on how to use the Studio Timeline:
When you select an object on the Stage, the corresponding object timeline is highlighted:
Per animation effect that you add, an additional sub-timeline is added for that specific effect. Your can hide these sub-timelines using the small arrow left of the object name.
To add an animation to an object: you can click the little arrow next to the object name and select "add animation". From the animation menu you can then choose a standard animation, or a specific animation if the object you selected contains such an animation. Eg. the Hand Writing animation can be applied to text objects
The lines on the Timeline also represent Object Layers: when two objects visually overlap each other on the stage, the object higher on the timeline will be in front of the object lower on the timeline
Once you’ve synchronized your objects, you can preview your animation by clicking the Play button. Click the fast-forward or rewind buttons to move forward or backward on the timeline.
You can also collapse and expand the Timeline view: When you collapse the Timeline view, you will just see the Clips you have created. When you expand the Timeline view, you see all the objects contained in your Clips. These buttons are found on the left side of the Editor, directly above the Timeline. You’ll see that the one you selected changes color from gray to blue:
