Some of that stuff is debris, you can tell, and space debris is just that, bits and pieces left out in space. We are polluting our own atmosphere much the same way we are our planet and apparently there is over 1 million bits and pieces of spacecraft floating around in orbit, much of it less than a penny in size. Things like booster rocket fragments, pieces and fragments from old satellites hit by meteorites, etc. Even heat shield tiles are floating about and that is just what we know off. Some of the clips are clear they are pieces of things that are small and rotating quickly in space as they float past quickly. But some of the lower orbit stuff looks more man-made like an aircraft, and we have to remember that they are testing incredibly fast and incredibly high altitude aircraft. In fact only the other month a top secret NASA aircraft was landed that stayed out at the edge of space for a year doing secret projects. It was filmed and documented on the news its landing and then weeks later its return to the edge of space to do another 18 month "test" doing secret projects for the government. Whatever it is doing, it is likely it gets seen from rare time to time by astronaughts, the ISS and more importantly the camera's that video the earth, and as such probably this craft (google it, its not a secret craft, just an experimental one with a top secret payload) is what the videos are showing from time to time!
