Managing luminance of video streams for display on HDR displays is provided. The luminance values of frames of a video stream can be monitored, and an over-bright frame can be determined if a luminance increase greater than a given luminance change within a given period of time. When a brightness jump exceeding given parameters is detected, the luminance values of the over-bright frame can be reduced. For example, luminance values can be reduced by reducing the luminance values of the over-bright frame such that the change in the average luminance is brought below the given value, and the luminance values of the modified frame can maintain relative luminances among pixels. A modified frame can be determined from the over-bright frame based on the reduced luminance values. The modified frame can be inserted into the video stream and transmitted to an HDR display to be displayed.
