This is the ending credit for the game Final Fantasy 7 Remake. The ending credit uses clips from the cutscenes in the game. I've seen this kind of method of using part of the flim in the ending credit in other movies too. Is there a name for this method?
Sounds like a montage in the end credits.
TV Tropes calls this a Credits Montage:
The credits are rolling! Wasn't that a great show? Let's all reflect on the great moments we just watched... ah, here they come now, and they brought a stirring, victorious musical track, too!
In short; the credit sequences of TV shows, movies or video games include a montage of stills or clips from earlier in the show.
