Abstract: Methods and apparatus for contextual video content adaptation are disclosed. Video content is adapted based on any number of criteria such as a target device type, viewing conditions, network conditions or various use cases, for example. A target adaptation of content may be defined for a specified video source. For example, based on receiving a request from a portable device for a live sports feed, a shortened and reduced resolution version of the live sport feed video may be defined for the portable device. The source content may be accessed and adapted (e.g., adapted temporally, spatially, etc.) and an adapted version of content generated. For example, the source content may be cropped to a particular spatial region of interest and/or reduced in length to a particular scene. The generated adaptation may be transmitted to a device in response to the request, or stored to a storage device.
