Bonjour
In the major part of videos about a sensitive subject like ecology, mental health or sharing, one of the most current particularity is the theme music. The videomaker put a music that accompany the theme. A sad song with a sad theme, a happy song with a happy theme, or a "thinking" song, with a subject that you have to think about. So in a ecology video, the music theme is really important to focus the viewer. Throw the music, you can feel anytypes of emotions, and you can feel concerned when watching a video about ecology just because of the music theme.
J'espère que je t'ai aidé ; le thème musical n'est pas quelque chose auquel on pense automatiquement en regardant une vidéo mais c'est un facteur important qui influe sur l'attention du spectateur. Bien sûr, tu peux ajouter les facteurs visuels qui sont tout aussi importants. Bon travail !
