The bigger problem is recording taking too much cpu. That's why I don't record full work day, just chunks, whenever I feel I procrastinate. Youtube is an option here, I've tested it however cpu problem doesn't go away.
My plan is to make this obs-ndi plugin work on ubuntu, so I will be able to record on ubuntu to take the load off of mac which is my primary laptop.
PS. I forgot to read obs-ndi instructions properly, it works ok so now I can delegate regording to second laptop
It wouldn't be huge, I once recorded a week of me using my pc(so around 80 hours in total), and it was sub-100 gigs. It was 1080p with decent quality, don't remember FPS though.
You get unlimited free storage of your streams for your personal use that way without the need for any local storage at all.
I haven't come across any limits or downsides to this yet but happy to be corrected.
