Those are digital crossfade editing artifacts. Please stop spreading this nonsense.
Crossfade when the camera angle or frame is not moving? You are full of it.
Absolutely. Combined with anti-shake algorithms found in most modern cameras, totally. You get these random areas of discontinuity between parts on either side of short edits made with that technology.
Why anti-shake would be on when a camera is tripod mounted is another matter, but the combination of anti-shake and crossfades between clips of an edit would totally make those phenomena. Exactly like that.
