Abstract: An edit data creation apparatus and method creates edit data specifying editing contents to arbitrarily combine edit materials. Positions of the edit materials are moved on the edit data. Adjustments are made to an end point of a first adjacent edit material upstream of the relevant edit material, and to a start point of a second adjacent edit material downstream of the relevant edit material according to the amount of movement of their respective edit materials. As a result, even if the edit materials are moved, it is possible to maintain the continuity between the adjacent edit materials on both sides and the moved edit material.
