For those who do not know, the Rockstar Editor is a set of various tools that you can use to compose and edit videos, make music videos and other projects, up to full - fledged movies. And its appearance in Red Dead Redemption 2 is quite expected.
And here is something that suggests such guesses:
0x96CC2F3D = Rockstar Editor
0x5B3AF9E3 = Save replay clip
0x5295B946 = Max Streaming Replay Size
0xBBF6A9FA = Bytes Per Replay Block
Regarding Mexico, we can safely say that it was originally in the game scenario, so some of the names of locations may occur due to this.
