Not to burst your bubble but... You know IR photography. The field wasn't fully lit by IR light. The video does show the field and bright flash of light. The "observers" didn't notice anything until daylight was breaking. Yes, they did prove as was mentioned in the video, that no laser aligning devices was used. Well maybe not. The bright flash could have been a laser device pointed at the camera and their direction.
They also suggest that they a night vision scope. Sony makes a "night vision" camera that is IR and not a "starlight" scope. The videographer just happened to be in the right place at the right time. Does he have a special connection to ??? I find the video interesting just the beginning appears flawed to me.
Just my 2 cents.
True IR as in the kind I have, do not light up a object, they just magnify the ambient light 1000's of times. While there cameras where not even close to the sensitivity off mine, you still would have seen motion if people where working in the field.
Boy would I love to set my system up at a crop circle hot spot...... But I don't know of any in the US??
BTW, here is a picture taken from my surveillance system in the middle of the night. The top picture is standard IR like they used in this video, and the bottom is my high-end IR camera in total dark.
