Instrumeteor: Authoring tool for Guitar Performance Video

To show off their playing, musicians publish musical performance videos on streaming services. In order to find out typical characteristics of guitar performance videos, we carried out a quantitative survey of guitar performance videos. Then, we discuss key problems of creating effects informed by the survey. According to the discussion, authoring videos with typical effects takes a long time even for experienced users because they typically need to combine multiple video tracks (e.g., lyrics and videos shot from multiple angles) into a single track. They need to synchronize all tracks with the musical piece and set transitions between them at the right timing, aware of the musical structure. This paper presents Instrumeteor, an authoring tool for musical performance videos. First, it automatically analyzes the musical structure in the tracks to align them on a single timeline. Second, it implements typical video effects informed by the survey. In this way, our tool reduces manual work and unleashes the musicians’ creativity.
