2 interesting UFO videos, what was filmed?

First one is something much nearer to home, could be the ISS but you can't do the stuff unless you have all the gubbings. more info needed. However the ISS has a constant trajectory, and it's not easy to see that is what's happening in that video. To add, he was already Zoomed in for something of interest so he says, but has surprise when what we see shoots by..I don't buy that bit.
Second one has something highly reflective seen several times as well as possible lighting and a helicopter comes close.
