 Genre is read by the opening, from the music, setting, lightning or editing. for example jump scare musics at the start tells the film is horror, low dim light can represent horror, also it can be sad genre, music of film archives a number of things like it creates atmosphere, it establishes the setting, it  reinforces the narrative development. Other than music the settings can show the genre, setting with unreal things can be an action film or an abandoned area, an abandoned house represents the horror film, in suspense movies the characters are not shown at start, there are some hiding things about the character that audiences want to know about them.
