I'm gonna vote for editing as well. The kid is casting a shadow about as long as he is tall, suggesting the sun is about 45° above the horizon. The bus' shadow falls directly beneath it, meaning the sun would have to be more or less overhead.
The reflections in the puddle don't pass muster, either. The angles don't look right. The reflection of the bus filled the puddle entirely and included the top of the yellow sign on the side of the bus. The top of the car was close to the same apparent height as the yellow sign. Being closer to the puddle, at least a portion of it should have been reflected...rather than none at all.
Finally, notice how the puddle darkens considerably as the kid runs back toward the camera. During most of the video, it seemed to reflect bright overcast. In the span of about three seconds, it looks like dark rain clouds move in. However, the overall scene brightness doesn't appear to change.
