beat = 1/ is the denominator of your time signature, while beats per measure is the numerator. current sounds are pop and dog. bpm is the speed.
it might speed up due to inconsistent framerates. if so, idk use a real metronome songs that are weird: tool - schism: 108 bpm, 12/8 led zeppelin - four sticks: 214 bpm, 5/4 pink floyd - money: 128 bpm, 7/4
