Network-based event recording

A system comprising a computing device including a processor and a memory, the memory storing instructions executable by the processor such that the processor is programmed to:

• receive, from a media device, a primary media content item including one or more segments, and primary metadata associated with the primary media content item, the metadata including user mental state data;
• select, based on the user mental state data, an audio content item;
• and
• generate a secondary media content item, based on the primary media content item and the audio content item.

A method comprising:

• receiving, in a media device, sensor data indicating a field of view of a user of the media device;
• adjusting a field of view of a video capture device in the media device to correspond to the field of view of the user;
• receiving, from the video capture device, media data;
• storing the media data, together with metadata including time indices for each of one or more segments in the media data;
• receiving user input to generate a primary media content item based on the media data, the input specifying a start time of the primary media content item;
• generating the primary media content item from the media data, starting with the segment of the media data having a time index corresponding to the start time;
• and
• storing the primary media content item.
