looking to get in to speedrunning with the very interesting title, :The Longing:, going for a "400 days" ending, and after getting the numbers from the devs, it turns out it will take a minimum of 12 days to complete (hell of a speedrun i know), and i want to record the whole thing, but i dont know how big a 12 day long mp4 will be, even if i put it at 360p and terrible bitrate and frame rate. luckily, i have an empty 10 TB hard drive i got as a gift a while ago, but even then...

ive been trying to find ways to calculate how much i need to record, or what parameters, but google has been no help, and the game being rather small, its been taking a while for the mods to get back to me if i can take any liberties, so if anyone knows any tools, or is adept at this sort of thing it would be a massive help

Easiest way to figure it out would be to record gameplay of it for about an hour, and the multiply the size of that video by about 300.

To estimate the file size for your speedrun, you could start by recording an hour of gameplay at your intended settings of 360p with a low bitrate. Then, check the file size of this hour-long video and multiply it by 288, which is the total number of hours in 12 days. This calculation should give you a rough idea of the total storage needed.

You can get a good idea of how big your speedrun file will be by recording one hour of gaming at 360p with a low bitrate. Next, find out how big this film is; 12 hours is equal to 288, so multiply that by the file size of this hour-long video. An approximate estimate of the total storage required can be obtained from this computation.
