UFO activity spotted on moon (old but think about this)

You Tube Video

Start the video at 2:min, it happens shortly after. The crater is 20km across, so the object would be about 3k guesstimating wide. That's huge, but look at our flying triangles, supposedly stealth blimps that can carry massive loads of materials into space, so there for it's still plausible this UFO is real. In the comments posted below on You Tube they mention there are multiple videos showing activity in this crater from different dates. So what has been determined of these videos, as I'm sure they have been discussed on here before, and even if they are debunked, enlighten me as to why.

As the moon moves in the video so does the object. That can only mean one thing. Theres something on the lense.
Or somekind of a dead pixel.
