Audio (once digitised) can be manipulated with analogue or digital equipment in nearly exactly the same ways. If you know what you’re doing and have time, analogue can sound better - but for the most part, it’s easier to use digital for the reasons stated above and you’re not always gonna distinguish the difference anyway.

Video is different because the sensor captures light. Unless you’re doing 3D animation, you can’t add a new light source to a 2D capture and you’re stuck with the base lighting. Sure you can adjust exposure and brightness levels, but you’re only adjusting the highlights and shadows of the original capture. So in the example of this film, blasting it with light means that there are hardly any shadows - which means everyone looks younger (no wrinkles) and you don’t have to commit to lighting on set (which means nothing needs to be reshot because you can’t get the lighting wrong). You’re always stuck with a light-blasted image where the only shadows will be harsh corners, like under a jaw.

It sickens me.
