Frame Rate Conversion is the process of changing the number of frames displayed per second in a video. This is often necessary when adapting content from one format to another, such as converting a movie shot at 24 frames per second to a format that plays at 30 frames per second or 60 frames per second. This conversion helps ensure smooth playback on different devices and platforms. Various techniques, such as interpolation or frame blending, can be used to create new frames, maintaining visual quality while adapting to the desired frame rate.
