I know exactly what it is, and apparently one of the people who commented also arrived at the same conclusion as I did.

It's a video of Venus taken through an optically poor lens (like a home video camera). You will note it's not moving when he zooms out, and it shows a crescent (and some astigmatism) when he zooms in, and it is low to the horizon.

I would have been able to prove it if the jerk who took that video had bothered to note the date, time, location, and even a rough estimate of its elevation and azimuth.

That's what really pisses me off about these UFO weenies. They show you the gotcha picture and then they don't even think of writing down a few pertinent facts so you can eliminate some of the alternate explanations.
