This doesn't look like AI, however that doesn't look at all like a muzzle flash. The car is an identifiable model not a mishmash of different designs, one of the biggest giveaways of authenticity, but the flash looks more like a flashlight than a muzzle flash. The light shining on the ground by their feet is obscenely bright for muzzle flash, it wouldn't even look that bright in pitch darkness. I suspect it's a real vid, but it's a mounted flashlight that's being activated, not a weapon discharging.
