Frame rate, also known as frame frequency, is the frequency (rate) at which an imaging device displays consecutive images called frames. The term applies equally to film and video cameras, computer graphics, and motion capture systems. Frame rate is usually expressed in frames per second (FPS).
With the recent virtual porn craze happening, other, less popular technologies have made there own niche out of porn. Porn shot at 60 FPS adds a certain level of realism that standard video shot below 60 FPS does not. But, there are two kinds of 60 FPS porn videos: Native and Interpolated.
What’s the difference?
Native means that a video was shot at 60 FPS
Interpolated means that a video was shot at less than 60 FPS. Then, special software is used to fill in the gaps between existing frames and bring the video up to 60 FPS.
Reddit has a subreddit that is a collection of 60 FPS porn clips.
