Abstract: Individualized, adaptable media presentations and a method for creating them are disclosed. In particular, each media presentation is generated according to user input and predetermined templates, overlaid with at least an instruction and an accompaniment layers generated from media clips (audio, video, audio/video) selected based on provided user data. The instruction and accompaniment layers are variable by the user and may then be overridden by the removal and replacement of individual media clips within the layer. The method and resultant media presentations as seen as ideal for exercise and physical training regimens, though may be utilized in any situation where recreation and instruction media presentation are used.

Abstract: Mixing individualized media content. When individualized media content is generated from separate media clips or files, mixing the separate media clips includes controlling the audio. The volume of the audio in each clip is determined and normalized with respect to other media clips as the individualized media content is mixed. This provides a consistent audio experience even when the media content is generated from multiple sources having different properties. When more than one track of audio is present, such as voice audio and background music, the volume of one track is lowered such that the other audio track is audible. The volume of the background music, for example, is reduced such that the subscriber can hear the instructions in the voice audio.
