This application provides techniques of generating interactive videos. The techniques comprise obtaining an original video, creating an interactive track for the original video to obtain an initial video, and adding an interactive component to the interactive track; and generating an interactive video by rendering at least one interactive video frame and other video frames of the initial video based on the interactive component. In this way, an interactive video with an interactive capability can be generated without additionally adding a data channel to implement an interaction function, thereby reducing processing load of a terminal and reducing resource consumption of the terminal.
