It is definitely computer-generated. The beam is green light, but the 'daylight flashes' of the house and street are polychromatic light that could not have come from either beam directly or atmosphere glow from lightning-like discharge. Yes, lightning flashes white but the duration in the video at 1:03-4 was too long for lightning which is milliseconds. Also the flash illumination comes from the wrong direction. Fake.
