So I'm new to SpeedRunning, and specifically want to do it with Dot hack (the new PS4 remaster). I have a twitch account connected to my PS4, and can set it up to my YouTube if needed.

I tried looking for solid answers before posting, but I guess I'm worried to do anything before I start. In the Rules for the PS4 Any%, it states to have a timer with the game.

Since I have no capture card or what have you, all I have are the above mentioned platform. Would this be enough for proof for when I do the game? I realize there's always a possibility of cheating for some runs, but I guess I want to make sure that I can do everything correct with the resources available.

(TL;DR) Would like to use twitch/youtube for evidence of speedrunning of a game, is this possible?

Welcome to speedrunning Jixaws. Twitch Highlights are fine, as well as YT uploads. Although, an RTA timer is required for submission. Therefore, a capture card will be needed.

Well I just finagled with OBS and just timed the raw footage XD and currently waiting for twitch to get it fully uploaded. I'll work out a better solution for the next run I do since I understand OBS more.

But still, thank you for the clarification! You guys have been very helpful with the whole thing. Soon enough you'll be seeing my submission ;)
