After several seconds without an image, a dark-and-light blob crosses the screen. It enters at the upper right and disappears at the lower left.
The video was apparently filmed in 1996 with a sensor that renders heat as an image, on a U.S. military platform. But the movement is only part of the story: someone altered the video before it was submitted for examination. Who did so, what they changed, and why remain unknown.
One Blob, Then a Replay
The video runs for nearly three minutes. After the blank opening, the blob appears briefly and crosses the field of view. It leaves the frame, and the video offers no follow-up showing where it went or what happened next.
Instead of cutting to new footage, the video replays the segment in which the blob crosses the screen. The same movement appears once more, this time in slow motion. Near the end, the image freezes on a single frame from the beginning of the video.
What Happened to the Video Before It Was Examined?
The video was submitted for examination by a team in the U.S. Navy. According to the official description, it had been digitally altered before it reached the team. The description does not specify what was changed, who changed it, or exactly when.
The video was later transferred to a U.S. government office that investigates phenomena of this kind. The office said it presented the video as received. At the time the video was reported, no official procedures were in place for handling material of this kind.
What Remains Unknown
It is not known what produced the blob, what the event was, or why the video was altered. The official description offers no conventional explanation for what appears in the footage, nor does it determine the source of the movement.
In the end, one frame from the video remains. The blob is still crossing the screen, but who altered the footage and what it shows remain unanswered.
