There does seem to be slight leakage during burner operation particularly from this one top burner.
is this common or do burners need replacing?
It acually sounds more like flame roll out
How old is this unit?
Goodman had a problem with the rings coming of of the heat exchager.
this will cause the flames to jump off of the sensor losing flame sense.
Also check your air filter this can also cause your flame to blow back
