I should consider possible interpretations. If this is a documentary, a feature could be its cinematography, the subject matter, a particular technique used, or thematic elements. If it's a video from a festival, maybe the feature is how it integrates elements of Perugia's culture. Alternatively, it could be a fitness video (since "Forza" means "Force" in Italian, and Perugia has a football team, Perugia Calcio), but the name "Chiara" might point away from sports.
