: Why is 4K footage of a game bigger than the game itself?

1.16K views

For example, The Last Of Us Part II is near 100 GB, but if I record the whole game (20 hours or so) in 4K, that video will be like 200-250 GB.

Can anyone explain why?

The best reason I could see is because the game probably reuses certain assets, possibly just re-skinned.

Like enemy 1 and enemy 2 are actually equal, just colored different. The same with some buildings and grass, that sort of idea. Think of older games from the 80s and 90s where a stronger enemy is just a different color palette. A lot of that was to save storage space.

Now when you record something nothing is reused, enemy 1 and enemy 2 are both unique pixels that take up equal space.

There’s also the fact that there might not be 20 hours of straight up assets. I’m not sure how to explain this well… but you have to sit and play the game which would take longer than if you just looked at each asset of a game and were done.

Sort of like let’s say everything in the game was in one map and you beat it in 30 minutes. The game would be the same size but your video would be significantly smaller.

A good example of this too is Resident Evil 7. Game is only 20 gigs but unless you speed rum it, it’ll probably take you 10 hours and a larger video than game.
