An apparatus and a method for distorting add-on graphics to be composited with a streaming video feed comprising, receiving a streaming video feed captured using a real camera, said streaming video feed including an image frame taken from a particular view point and a particular field of view, said real camera introducing image distortions into the image frame, measuring a plurality of camera instrumentation data corresponding to at least said view point, said field of view, and a distortion parameters corresponding to the image distortions of the image frame, creating a virtual camera, setting the virtual view point and the virtual field of view of the virtual camera using the plurality of camera instrumentation data, generating add-on graphics having a size and an insertion position within the image frame based on the virtual camera, creating a distortion grid, distorting the add-on graphics to match the image distortions of the image frame, and compositing the distorted add-on graphics with the image frame of the streaming video feed.
