"I think Bigfoot is blurry, that's the problem. It's not the photographer's fault. Bigfoot is blurry, and that's extra scary to me. There's a large out of focus monster roaming the countryside" Mitch Hedburg

If someone takes a funny video of a random person on the street, and it's blurry, OF COURSE they're not going to post it or show it to you.

But if it was Jesus, Mohammed, or Aliens in front of you, you'd probably still show the clip...even if it was a little shaky due to your adrenaline..

but there is no way in hell a chance to get a single good reel of few seconds of a clearly visible UFO,

this of course adds a lot for the "is not aliens" team

Because they have systems designed to degrade photography to reduce believability of sightings and discredit people reporting them.
