At 4:30, light from the burning meteor reached the video camera. At that time the meteor was still in the air it did not generate the sound wave on impact yet. After 150 seconds the sound waves reached the video. This means that the point where the sound waves were generated was at a distance of 333 m/s x 150 s = 49.95 Km from the spot where the video was shot. Now the reason for generation could be either because the meteor exploded in air and we are hearing the explosion sound or the meteor hit the earth as one major chunk of rock (along with other tiny pieces) and we are hearing the sound due to impact. I guess is that since we hear one big explosion followed by multiple smaller explosion, the meteor has just exploded into several pieces jut before hitting earth. The first explosion is due to the exploding meteor and the smaller explosion are due the pieces hitting the earth.

At 4:30, light from the burning meteor reached the video camera. At that time the meteor was still in the air and it did not generate the boom. After 150 seconds the sound waves reached the video which means that the point where the boom were generated was at a distance of 333 m/s x 150 s = 49.95 Km from the spot where the video was shot. The reason for the boom could be either because the meteor exploded in air due to heat caused by air friction or because the meteor hit the earth as one major chunk of rock (along with other tiny pieces) and we are hearing the sound due to impact.
