Abstract: A computer-implemented method of generating an overlay of medical video data and overlay data is presented. The method comprising the steps acquiring, from a medical video modality, the medical video data comprising at least a first video frame and a second video frame of different points in time, t1 and t2, (step S1), analysing the acquired medical video data comprising a comparison of the video data captured by the first and the second video frames (step S2); providing initial overlay data (step S3), generating modified overlay data by adapting the initial overlay data based on a result of the analysis of the medical video data (step S4), and generating the overlay by generating a video output comprising at least medical video data originating from the medical video modality and comprising the generated modified overlay data (step S5). In a particular embodiment, the determined change over time in the first and second video frames is a spatial shift of an object imaged in the video frames.
