Methods and systems for selecting a preferred viewpoint for media assets
Methods and systems are provided for a media guidance application that customizes media content based on the preferences of a user. In particular, the media guidance application may select a particular viewpoint from which to present the media content to the user. In such cases, the media guidance application may select a particular camera angle from which to display the media content (e.g., when media content is available from multiple camera angles), may create a particular camera angle using data received from a plurality of cameras (e.g., when media content is presented in a free viewpoint environment), or select a particular object to focus on (e.g., when the media content is captured using a plenoptic camera).
