How to take an object and pause it in a moving video?
In simple terms you split the video at the frame you want the objects to join up at, then also make a still image of the object at that frame (Layer 1 = video end of sequence, Layer 2 = still image Layer 3 = video beginning of sequence). If the camera is moving you will have to track the still object to match Layer 3. So the still image gets closer to the moving object as Video/Layer 3 plays, then when the objects join video/layer 1 cuts in and continues.
