I agree this is a defocused video of a small scintillating light source. But I think it's a star. The lateral drift with insignificant vertical motion _is_ characteristic of a non-setting star near the southern horizon. Judging from the way the camera is placed - on a window sill or similar - it seems clear that it is pointed near the horizon. The maximum angular motion of any star during 1 hour (total video) is only 15 deg at the celestial equator, and near the S horizon it would be much less. Moreover the video extract as I recall is only about 12 minutes, so the motion is likely no more a few degrees, too small for significant altitude change to be discernable. The camera is said to be at maximum zoom so the angular FOV is small and it doesn't take long for the star to drift across it. The witness herself says on the video "When I look just with my naked eye it looks like...a star". I believe it was taken from Vancouver in the early morning? The brightest star Sirius would have been low on the S horizon and is the champion of twinklers in this sort of situation. Martin Shough Listen to 'Strange Days...
