Why does audio and video take so much storage?

414 views

So for example, videogames are super heavy on disk space. And aparently most of that space is just the sounds, textures, models, etc. But the code takes very little space.

Why can something as complex as a physics system weight less than a bunch of images?

Code takes very little space, media takes more. But an image is just code that tells the computer how to draw something (I think)

So how come some code gets to be so small in size and some code doesn’t?

I have an image (a texture) in front of me. One pixel is green. What colour are the ones around it?

The bottom line is – you don’t, and can’t, know. Sure, I told you it’s an image, so there’s a good statistical probability they will be green as well – but you don’t know that. The only way to be sure is to look. And when it comes to storing it on a drive – sure, there are compression techniques you can use to cut it down in size somewhat – but in the end, you’re effectively storing something akin to random information. That takes up a LOT of space. And sound is basically just the same.
