All video is intended to be delivered and watched on some kind of display device.
How does Colour space affect digital displays?
Using a larger colour space enables users to retain the full range of colours their cameras can capture in raw file format. This will help prevent the posterisation and data errors that can happen when a wide colour gamut is crammed into a restricted colour space like sRGB.
