TV creates the pictures by displaying it line by line - scanning from top to bottom. This scanning is done at a particular frequency. Film cameras shoot multiple shots per second known as frames per second (fps). When the fps and the frequency of any moving object do not match it will cause a stroboscopic effect. This causes effect of the lines scrolling up. A similar effect can be seen in films where it shows the hub caps of a car or the propeller of an airplane which is speeding up. First it goes reverse, slows down to a stop then goes forward.
