Thank you for your quick response! Have a nice day!

Hi Vadim, My answer is yes. The meaning does change. The first sentence is clear that something was used in the credits of the film. The second sentence could imply that "it" was used before the credits.

Hi Vadim, The end credits of the film refers to the segment after the movie where everyone who worked on the film's name are listed and credited. e.g actors, production, management, director etc. The end of the film can just refer to the end of the actual show/movie itself and not include the credits., so it's a minute difference just referring to a slightly more specific part, but they do have different meanings.

Howdy Vadim! Yes, the word credits does change the meaning of this sentence. If one talks about the "end of the film", it might imply the end of the main body of the film, the last moments when there are actors onscreen. However if you say something is used for the end credits, then you are making it explicit that you are referring to the period of the the film after that when the list of names of people who worked on the movie is rolling.
