Add a Keyframe
Open Studio and add any object (2D or 3D). In this example, a 3D disc has been added to a player.
Move the video forward using the video tools or shortcut keys.
When you have moved the video forward, click and drag the center of the object's bounded box to the player's new position.
A white diamond keyframe marker will appear on the blue timeline instance.
Use the right arrow key to move the video on frame by frame for greater accuracy.
Repeat the above steps until you have tracked the identified player for the full duration of the timeline instance.
You will see that the timeline instance is now populated with multiple white keyframe diamond markers.
