In a device and method for integrating a prerecorded video file into a video, a video of a scene is displayed on a display device of a mobile electronic device. A prerecorded video file to render on the display device is received. A modified prerecorded video file is generated by modifying a visual appearance of the prerecorded video file, where the modifying is for integrating the modified prerecorded video file into the scene. The modified prerecorded video file is superimposed over the video, such that the video is partially obscured by the modified prerecorded video file. The modified prerecorded video file is played while displaying the video, such that the modified prerecorded video file and a non-obscured portion of the video are rendered simultaneously.
