I was shooting few videos of the evening sunset which I usually do via my Lenovo mobile phone.Later when I imported the videos, this one had a peculiar image in frame no. 002, I thought it could be some dust or some camera issue.But yet this is peculiar.None of my other videos have such a distortion.Please find attached video and a screenshot of that particular moment.I need to know what this could be?UFO? or just some dust, but this is too fast and the shape is interesting.I have submitted the video as is, I have not done any editing via any software.The screenshots are of the video.
