Abstract: Embodiments relate to a web-based interactive fitness program for generating individualized fitness media content for subscribers. A database is maintained that includes scriptlets that identify exercise routines that have been provided or augmented by a trainer. One or more of the scriptlets are selected for a subscriber based on the subscriber's information. The selected scriptlets are then compiled into media content that is streamed to the subscriber for use. Various devices associated with the subscriber may provide real time input to the database while the subscriber is experiencing the media content. In response to the real time input, new scriptlets may be selected and modified media content may be streamed to the subscriber for use.

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.

Abstract: Generating navigable media content. A knowledge base stores content from multiple sources including subject matter experts. Specific content is identified from the knowledge base using attributes of a subscriber. The specific content corresponds to media clips that are mixed to generate individualized media content. The media content is then formatted with navigable elements that enable a user to navigate and perform the media content in a manner that is determined by the subscriber. The navigable elements may include chapter marks, or a menu that can be presented on the subscriber's device, for example.
