Content characteristics and emotions of urban virtual reality promotional videos
Fifteen urban virtual reality videos were selected as the research objects.Based on content analysis and emotion analysis,the content characteristics of urban virtual reality videos were analyzed in detail,and the emotional tendency of video viewers was deeply explored.The research has found that some videos have unreasonable duration settings,limited content related to urban history and culture,lack unique urban signage,overuse of multiple filming techniques,most videos lack interactive experience content,and the background music is mostly ordinary music.The audience's overall emotion towards the video tends to be positive,and the negative emotion mainly comes from the video quality and background music.Therefore,it is proposed that the video duration of urban virtual reality promotional videos should be controlled between 2 and 5 minutes,with a focus on exploring the city's historical culture and local customs,highlighting the unique symbols and signs of the city,appropriately increasing interactive experience content,avoiding blind use of excessive filming techniques,and selecting appropriate background music based on the city's characteristics.
