I know that UFO means something "Unidentified", but what you guess are about those objects?
On video is just dots, but you saw in person witch makes total difference, so what's your take?
I believe they are forms of Aircraft that Humans shouldn't have the Technology to create yet.
Remembering back, from the lights they shouldn't be larger than a Fighter Jet.
A brief backstory.
Around my Family's plot of land in 1999 there were few neighbours still; it was a cloudless black night.
I had a great view of the night sky, no obstructions whatsoever.
I saw two lights of those colours rise slowly from the Northern horizon to a midway point in the sky and stop dead.
A part of me wants to say I saw rotation at this time, but another part of me knows I can't be absolutely sure.
Then they moved upwards again, around twice the original speed for about a quarter of the height of the sky towards the North-West.
Then suddenly they moved so fast that the light basically disappeared from my visible horizon.
Not shrink, but streak away so fast it disappeared for my eyes.
One streaked away before the other followed.
I've seen plenty of Aeroplanes, Fighter Jets and Helicopters since.
There is no Technology we currently have that could do that, let alone without noise and back in 1999.
