The first two are the duplicate frames, the third is the next frame.
The differences that we see between the first and second frame is clearly the result in the shutter of the video camera also recording some parts of the third frame.
If that were true then why are some of the ghosting in the second frame from third frame objects don't always share the same position between the two frames?
"Forza" on the left wall and the post right under the rear view mirror are examples.
