Can it be fixed?
Maybe. If the tape is damaged and that video information is missing, then you cannot recover the image.
If it was an error on part of the deck, then you might be able to reduce the dropout by cleaning the deck and/or tape. This is a good way to determine if the dropout is the result of a headclog or damage to tape/deck. Try cleaning your deck and transferring the tape again. If the artifact is still in the same spot, the tape is damaged and that video information is missing.
