Abstract
Methods and systems for controlling judder are disclosed. Judder can be introduced locally within a picture, to restore a judder feeling which is normally expected in films. Judder metadata can be generated based on the input frames. The judder metadata includes base frame rate, judder control rate and display parameters, and can be used to control judder for different applications.
