In the video, a person is seen using a DJ controller to manipulate the sound of a song that is playing on a laptop. The DJ controller has a circular jog wheel in the center, surrounded by various buttons and sliders that the person is adjusting to create different effects. The person's hands are visible as they move the controller back and forth, pressing buttons and sliding the controls. The laptop screen displays a digital audio workstation with a waveform of the song, indicating that the person is likely mixing or remixing the music. The lighting in the room is dim, with the focus on the DJ controller and the laptop screen.
