"The uploader continued, the term refers to reports of luminous and spherical objects that vary from the size of a pea to several metres in diameter.

But the claim is false.

A Yandex reverse image search, followed by keyword searches on Google, found this 23-second video.

It was published on a YouTube channel under the name Andrei Trukhonovets on May 27, 2019.

The video title reads in English: "Ball lightning caught on video near railways [CGI]" — referring to computer-generated imagery.

In the misleading posts, the genuine video has been reversed.

Below is a screenshot comparison of the video in the misleading post (L) and the mirrored version of the genuine clip (R), with matching features circled in red by AFP:

 Trukhonovets, a Belarus-based 3D artist, told AFP that he created the video using the video-editing software Adobe After Effects and uploaded it to YouTube in May 2019.

He said he filmed the clip of railway tracks seen in the video near the Belarusian capital of Minsk.

"I tried to create a short story with a ball of lightning, imagined how it would have moved and behaved," Trukhonovets said on December 1, 2021. "Then I recorded a video with railways, imagining there's a moving ball of lightning on it."
