    I’m not sure that’s a JPEG artifact. It looks more like a video compression artifact (since the image is probably taken from a video).

        lol there’s a specific AVI format based on JPEG, but other file formats use different algorithms

          Pretty much all compression algorithms work similar to JPEG. The newer formats only add even more crazy maths to the mix, but the base is pretty much the same.
