First and last frames of Jellyfish UFO, they are clearly different, this isn’t poop or a smudge?

Hi, I posted the zoomed in video recently that gained a lot of attention, however I noticed 80% of the comments were repeating “Smudge”. I will admit, I kinda thought that for awhile until I decided to blow up the last few frames and directly compare them. As you know, the last frame shows it zoomed out a lot (hence the blurry image). Yet despite this, it’s clearly from a different angle. I consider this proof that it’s not smudge nor poop, but I don’t consider it proof it’s real. That’s on Corbell and Knap to prove to us, so let’s push for more info!
