Techniques for selectively associating frames with content entities and using such associations to dynamically generate web content related to the content entities. One embodiment performs a facial recognition analysis on frames of one or more instances of video content to identify a plurality of frames that each depict a first content entity. A measure of quality and a measure of confidence that the frame contains the depiction of the first content entity are determined for each of the identified plurality of frames. Embodiments select one or more frames from the identified plurality of frames, based on the measures of quality and the measures of confidence. The selected one or more frames are associated with the first content entity and web content associated with the first content entity is generated that includes a depiction of the selected one or more frames in association with an instance of video content.
