Small Irregularly Flashing and moving Orb/Circle

So i saw this completely silent, Flashing and moving Orb/Circle in the night sky. Every time I spot something, I routinely try and identify anything that I see in the sky in one of the following categories: bird, airplane, helicopter, drone, hot air balloon, weather balloon, ISS, Satellite, Firecracker (burst in India for many occasions during a year). What I saw that day, might still be one of these, but I was not convinced. It seemed different. especially because it seems not so far, but was completely silent, and seems to have a very unexpected movement. The video was taken from my cell phone, a Google Pixel Phone.
