This mod was created by using Red Dead Redemption Explorer (Link)

It replaces the current GTA V Rockstar Intro with the original one from Red Dead Redemption I exported from the Xbox 360 Game of the year edition, that is shorter and much cooler than the GTA one (sadly it's 720p only, but you won't notice that probably).
