Improvement of Presence in Live Music Videos and Alleviation of Discomfort of Viewers by Zooming Operation

Abstract

People can enjoy watching live performances without visiting live venues thanks to the development of live music streaming services on the Internet. However, such live music videos, especially those recorded by amateur band members, lack a sense of presence. Therefore, in the previous study, the authors proposed a method to improve the sense of presence in live music videos by performing zooming on the video frames. It achieved enhancing the sense of presence. However, it also increased the discomfort of the viewers. This is because the zooming was performed not on a music performer but in the center of the screen, resulting in an unnatural experience for the viewer. Therefore, in this paper, a new zooming method, which effectively emphasizes the music performer with intense movement, is proposed, introducing the concept of the “Main Spot”. The evaluation results through an experiment verified that the proposed method improved the sense of presence in live music videos and alleviated the discomfort of the viewers.
