What does it mean to dub the photographer?

Add sound to a movie or multimedia. Dubbing is the process of adding sound to a movie or multimedia, which means that the dubbing actor adds sound to the character or replaces the language dialogue of the character in the original film with other languages. When shooting, the original actor fills in the dialogue for the segment because of voice errors. When recording photography, the actor's voice or singing voice is replaced by others, which is called dubbing.
