The video shows a close-up of a smartphone screen with a list of Bluetooth codes. A person's finger is seen scrolling through the list and selecting different codes. The codes include SBC, AAC, aptX, aptX HD, and others. The person's finger moves slowly and deliberately, indicating that they are carefully choosing the code they want to use. The background is blurred, but it appears to be a wooden surface. The lighting is bright, and the phone screen is clear and easy to read.
