Here are a few interesting UFO videos worth looking at, no idea if they are authentic or not. To me they look like they are real, mind you it doesn't mean these flying objects are necessarily from another planet.
Onto the videos...the first one is shot in Australia.
Next we have a UFO shot (not literally) in Nanjing, China.
Another from Bulgaria
The next one is a commercial for the Sci-Fi channel, though I think it's fictional.
Finally we have a short talk from the Disclosure Project.
