You are going away, to some place isolated… in space, of course. You will only be around one other person. You can take an allotment if 1GB of personal media with you (text, video, music, games, pics, etc.) that you will be able to access in your free time indefinitely at will.
The other person will also take 1GB with them, but you won’t be able to talk to them until you’re on the journey.
You will have access to any knowledge resources to perform your function and keep you alive. You will never return to a point where you can get new external media. Any additional media you ever access would have to be created by you and or your travel partner with what you have access to.
You will also not know the sex of your partner, but they have willingly taken the same risks to embark on the journey as yourself, and will have a similar mission.
It’s 4kb it’s the demo scene.
To expand, the rendered to video output is much more than 4k, but the file that produces the output can be small like that, this is usually done by doing a bunch of math to generate the output dynamically.
You can kind of equate it to how a video game can generate 120 frames of 4k footage every second indefinitely, but the game itself is limited in size.
Recording the output takes up space, but you don’t need to record it if you can generate it in demand.
