As we explain in this below article, the plane-like roar was caused by a series of intense and rapid detonations at the explosion site shortly before the main explosion bellingcat.com/news/mena/2020

What this slow motion 4k footage does show is there's no sign of the supposed missile or rocket that some have claimed caused the explosion.

The noise and shockwave takes ~2.5s to reach camera, which seems placed on a stable surface (not hand-held). But it moves and twists at ~1s after the blast.
I'm curious what could cause the camera to move like this *before* the sound/shock reaches the camera.

Owner may have still had their hand on it and initial flinch from the visual may have caused that
Yes, maybe. After that first flinch the camera is steady, even as the shock wave comes. If they still had hand on camera at this point, they had nerves of steel! More likely, they had hand on camera when initial blast was seen, then let go in shock immediately after.
