Hello I am new and I would like to try a speed run of bendy and the ink machine on ps4 but I do not know how filmed and how the game time is displayed. (sorry for my english)

You don't need a timer on screen.

Stream your runs using ps4's twitch app, as long as you show your IGT at the end of the run you're golden

thank's
