What does "in you go" mean? Does it have the same meaning as "after you"? Could you tell me some examples?

It doesn't really have any meaning. It's usually spoken as a friendly commentary when someone is entering something, like a car, swimming pool, or in the case of this video, an elevator. It's especially often used with children or individuals requiring care. My guess is that the speaker is a lover of animals, so her care of the ducks is obvious when she says "in you go, ducks" as they enter the elevator. "After you" is different because it's more of a direction, so there is an intended meaning when one says it. Ex: In you go, dear. Let me buckle up your seatbelt. Ex: In you go into the car! Watch your head.
