Maybe the best method of approach is to examine the person first, rather than the video? I've found the UFO fakers normally get addicted to fooling people and will do it more than once. I also find a video more believable if it comes from someone who doesn't own a UFO Website/Blog and has no prior interest in them.
People sometimes wonder what the motivation for faking UFO videos are? Well let me tell those of you that might not know. Sometimes, it's just the obvious one that people like attention, but sometimes it's more than that. If you have a really popular video on a site like YouTube, it can lead to money and interest in whatever you are trying to promote. For example, if you have a really popular video channel you can earn revenue from advertising. You can also direct large numbers of people to your own Website/Blog and earn even more income from adverts/links on your personal webpage's. Money is the root of deception.
At a point in the future if a video is ever released that shows without any doubt that UFOs and Aliens visiting the Earth are real. For example, footage inside a craft with beings etc, I will still be in doubt the first few times I watch it, unless it comes from an official source with a statement and news conference. Let's hope it happens in our lifetimes because I'd prefer living in a world with a much broader outlook of ourselves and the universe we live in. I think it will improve all of our time on this planet and beyond.
