Didn’t they actually see the object on multiple radars using multiple types of detection methods? Assuming that’s true, the camera glare story seems unlikely.
The video states that there's something there, but its heat signature is causing the glare (the video is in IR). Was the object flying steadily and rotating weirdly throughout the video? You can't see how the object is flying, the smooth motion and weird rotation you perceive is the effect of the glare!
