Pre-rendering is the process in which video footage is not
The term pre-rendered refers to anything that is not rendered in real-time. This includes content that could have been run in real-time with more effort on the part of the developer (e.g. video that covers many of a game's environments without pausing to load, or video of a game in an early state of development that is rendered in slow-motion and then played back at regular speed). This term is generally not used to refer to video captures of real-time rendered graphics despite the fact that video is technically pre-rendered by its nature. The term is also not used to refer to hand drawn assets or photographed assets (these assets not being computer rendered in the first place).
The advantage of pre-rendering is the ability to use graphic models that are more complex and computationally intensive than those that can be rendered in real-time, due to the possibility of using multiple computers over extended periods of time to render the end results. For instance, a comparison could be drawn between rail-shooters
