Claims16
A method for inserting a graphical overlay on a video stream during a time period of a video stream, comprising the steps of:
- estimating a degree of motion of the video stream during the time period of the video stream,
- determining a degree of animation of the graphical overlay based on the estimated degree of motion, and
- inserting the graphical overlay on the video stream during the time period of the video stream,
- wherein at least a first and a second degree of animation can be determined, wherein the first degree of animation is higher compared to the second degree of animation, wherein the first degree of animation is based on an estimated degree of motion below a threshold and wherein the second degree of animation is based on an estimated degree of motion above the threshold.
