I know it's fake because some guy has an agenda out there to troll ufo believers with those exact same dot videos. The guy laments the fact that his
after effects tutorials and examples that take years and months to create, get under 1000 views, yet the 20 minute cgi fake ufo footage gets 10,000
views, mentioned on UFO websites and so on...
Here's one I prepared earlier.
100% fake, meant to look as fake as possible, done in 10 minutes using nothing more than mocha. after effects and stock footage from youtube.
These sort of 'ufo' examples are just so simple to make, if someone were to spend a little effort in giving them less cgi-ish motion, it'd get more
people.
