Hard to tell what it could be from just a video, but I would begin by removing the accessory belt and starting the engine for about 10 seconds, but not more than 30 seconds or so as the water pump will not be running.
If the noise is not there, then it's a pulley or one of your accessories. If the sound is still there, then the noise points to a more serious internal engine problem.
