Mouse teeth or herringbone pattern is the term for a distortion arising from deinterlacing video. They occur when two frames combined for deinterlacing are noticeably different. Similar distortions may also be referred to as tearing or line crawling.
This distortion is most noticeable when there is horizontal movement between the two frames, as the lines in the newer frame will be shifted in the direction of motion from the older frame. When the frames are combined a jagged edge (mouse teeth) will be formed.
Famous quotes containing the words mouse and/or teeth:
“A mouse does not run into the mouth of a sleeping cat.”

“A barnacle goose
Far up in the stretches of night; night splits and the dawn breaks loose;
I, through the terrible novelty of light, stalk on, stalk on;
Those great sea-horses bare their teeth and laugh at the dawn.”
—William Butler Yeats (1865–1939)
