if i do a speed run on a game and i play ps4 i cant use timer and idk how to edit a timer in the video

Timers are rarely required for submission, if that’s what you’re asking.

Timers are mainly used for the runner to know what pace they are on, not for moderation purposes. You can use a timer to accomplish this. Moderators use frame counters to retime runs, so no external timers are needed (for 99% of games)

Just be sure to check game rules.
