For objects that appear briefly in the scene of a video, we recommend using the Keyframe Visibility feature. In our example, we drew the rectangle around the driver’s license at the moment it entered the scene and added another keyframe at the point when it is no longer visible. We then clicked the second keyframe and turned off visibility in Keyframe properties in the Tools Panel. Keyframe Visibility can be turned on if the object reappears.
TIP: Do not create a new object layer for an object that reappears later in the video. Just create a new keyframe in the original layer and visibility will be automatically turn on.
