Making OBS capture ~1 minute of screen recording continuously (piefed.blahaj.zone)

I'm sure there's a name for this function, but you know that thing where your screen is constantly being captured but it only gets saved if you tell it to, and then it'll save the last minute or however long the buffer period is? It lets you capture cool moments in games and stuff? Yeah, that. Is there a way to make OBS do that? If not, does anybody know of an open source application I can use for that? It'd be really useful and fun.
Thanks!

I would recommend gpu-screen-recorder for this role, it has much less overhead than any other option (it is a cli app, but does have a gui available if that is what you prefer)

OBS can do it; the option you're looking for is 'Replay Buffer'. You can configure it under Output, if I'm not mistaken.

Very old source but this might still be accurate.

(Steam can also do this, now, if that's what you're using to play your games.)

Ooo thank you very much! I don't use Steam but I'll for sure give this a go.

Make sure you allocate enough RAM! I usually go for 10 minutes (600 sec), and that takes about 4gb at 1440p/60fps (although I allocate 6gb just in case)

Oh damn I don't need nearly that much but thank you! I'll make sure to tweak the RAM just in case.
