Forgive me, just checking in quickly and I forget the details of the recording, but two possible issues occurred to me -- compression, simply because the levels are high, and the possibility of an automatic gain setting being engaged. If I ever record on my phone or most videocams, that happens and the volume pumps up and down. If this doesn't apply, then excuse me and carry on!Maybe just try some videos at a lower volume? Mine are low/moderate levels because my neighbor is insane.
