How to create a video for a map?

How do I teleport and remove creatures in a video? Let's say I place a demon in the very corner of the map, add a move animation to it, set the starting point to -40, and add coordinates, then add a teleport effect. As a result, the teleport activates, and the demon appears (in reality, it just moves invisibly from the corner of the map to the center). But at the end of the video, I need the teleport to activate again, and the demon to disappear. I add the move animation again and send it to the corner of the map. Immediately after that, the next dialogue starts, but it doesn't move instantly to the corner; it continues to run (what a pest!). Can you tell me what to do?
