Objects at that range seldom are visible to the unaided eye in a dark sky, let alone in the bright sky that existed at the time of the video. Therefore, the object almost certainly was not a satellite.

An additional reason to doubt this was a satellite is that the illumination
angle in this position would be very small, close to zero (we would be looking
at the "dark side" of the satellite). So it should not be visible.

It could be a high-flying aircraft perhaps.
