Take this into account...

The camera is probably not picking up the sound through the
microphone, and is probably farther away from the "action" than you
may think. The microphone is probably close to the "action" and then
you would have the issue with sync depending on how well the engineer
is processing the data.

OR

The camera is picking up the audio and video, and the audio is coming
from a public address system, and the camera is physically located far
beyond the throw of the speakers. Thus you have the video happening
before the audio, since light travels faster than sound.

OR

Last but not least, I have noticed that video engineers sometimes
don't have a clue about what is going on musically during a video and
they just make it look good. You can see this happen when multiple
cameras are recording different instrument sections in an orchestra,
and then you see the timpani player banging away and there is complete
silence.

hahahaha
