Frame Rate

Definition

Frame Rate is the number of individual frames (still images) that are displayed per second in a video or film. It is measured in frames per second (fps). The most common frame rates in professional production include 24fps (the standard for cinema, which gives a characteristic "film look"), 25fps (the standard for PAL television in Europe and much of the world), 29.97fps (the standard for NTSC television in North America and Japan), and 60fps (used for sports and high-motion content). Higher frame rates (120fps, 240fps) are used for slow-motion effects.

Contextual Usage

The DP tells the camera operator, "We're going to shoot the action sequence at 120fps so we can slow it down to 24fps in post. That will give us a 5x slow-motion effect. Make sure the shutter angle is set to 180 degrees to maintain the correct motion blur."
