hey I've played through this game a few times and have 100 percented with all trophies, and now I'm thinking i'm going to speedrun. does anyone know of a way to record on ps4 pro without using twitch?

You can stream to a PC using PS Remote Play, and then use OBS to stream, or record PS Remote Play.

also what is the best difficulty for speedruns?

You can technically choose whichever difficulty you want but the fastest is Friendly Neighbourhood

ok thx

How do you do it with no pc and nothing else just the ps4

With no PC, your only option is to stream directly from the PS4.

Ok thanks
