It is the camera axis that has a (near)vertical orientation, pointed "at the sky". The up/down of this frame orientation is arbitrary in relation to gravity.

The changing reflection geometry of a bubble (or, differently, an aspherical mylar balloon) moving in relation to the landscape, the sun and a fixed camera is complex and the direct illumination need not even be constant because the ray path between it and a low sun "behind the camera" (whatever that means) can easily be interrupted by trees, poles, buildings etc. There're really no grounds for assuming this thing is self luminous or is anything other than a mundane object (bubble, balloon etc) until you have started to do some of the type of investigation of angular relationships and camera orientation/surroundings and local winds etc that I suggested already, to try to put at least approximate bounds on possible size and rate and altitude (coupled variables) and direction, for testing predictions of bubble/balloon theories. You may be able to prove yourself right. Until then this is not very interesting for the rest of us. Martin Listen to 'Strange Days...
