Screeching/rattling sound

Does anybody know what the sound is? There’s no rhyme or rhythm to it. It just kind of starts making the noise when it wants to. I would look into it myself, but I don’t have any ramps or a proper jack yet. I just bought the car a month ago. I’ll attach a video for the sound

There is no way to determine the origin from that 4 sec video with such a limited perspective.
