I am seeking a scientific explanation behind this phenomenon which is unprecedented to me.

I was performing a piece on a music keyboard. I was filming it with my phone’s camera as well as recording the sound via the keyboard’s built-in tool.

After reviewing the recordings, the film and the keyboard’s recording simultaneously stop emitting sound at the same exact millisecond.

This infuriated me quite a lot, but now it intrigues me. What happened there? I am willing ro provide more information if needed.

    It’s an old Casio keyboard. The phone, a samsung, is not plugged to anything and was recording separately.

    I will try recording the exact song later and see if the issue persists.

        I think I have an idea now what the issue is?

        The keyboard stops recording after 4 minutes. So now, the trickier part is to explain the correlation between the keyboard and the phone. The abrupt stop of the keyboard’s recorder affects, in a yet inexplicable way, the phone’s camera.
