How much storage do I need and what codec should I use for large video files? (sh.itjust.works)

I'm planning a huge playthru of a game, and I'd like to be able to look back at it years down the line. However I'm expecting it to be 100s of hours (maybe around/over 1k, but I hope not longer than 2k) and years to finish (I'm not planning on playing 8+h a day).

What are he most optimal settings for OBS to save as much video as possible, while it's still watchable?

I could record in 1440p 165fps. I know that's dumb, but idk how low I'm willing to go. 1440p sounds awesome, but lower than 1080p would lose too much information. Same with lower than 60fps. I don't have a clue as to what bitrate would do well, and what encoding is best. For bitrate I have a clue that it needs to be as high as possible. As it can be a bullethell and there are way to many particles/effects on screen, while everything that matters is small. (I'm not trying to be secretive here, game's modded Terraria)

I'd also state that I'd like to error on the storage side, I don't mind buying another HDD, they really aren't that expensive. And I'm also planning on editing the video down as soon as possible, so that I delete all the boring parts. Meaning I probably won't have all of that lenght on my disk at once.

Thank you for any aid in my crazy endeavour.

well I checked. My GPU does support AV1, but only decode, and OBS doesn't support h265. So is my only (good) option is to use a SVT-AV1? How slow it that really?

and OBS doesn't support h265

are you sure about that? I'm pretty sure it should. maybe you'll find it as _x_265, as that's the name of the encoder it uses

I can't find it and a quick google told me that neither do others

OBS allows you to use everything FFmpeg supports with the "Custom Output (FFmpeg)" recording type.

I was and am searching there I just can't find it in the dropdown. I might be blind, but I checked multiple times.

Settings -> Output:

Output Mode: Advanced
Recording -> Type: Custom Output (FFmpeg)

I've gotten that far, but no farther

turns out OBS does not have a software encoder for it, only encoding with a hardware encoder is supported. it is mentioned in the 2nd table of the video formats heading herev https://obsproject.com/kb/audio-video-formats-guide
