A method of conceptually magnifying video browser data, the data being organised hierarchically in one or more levels ( 304, 312 ) is disclosed. The method comprises firstly selecting a parent level ( 304 ), the parent level selection making visible a first key frame ( 340 ) associated with the parent level ( 304 ). A magnification mode is also selected, being either a parent-only, or a parent-children magnification mode. Conceptual magnification is then performed, which displays, in the parent-only mode, the first key frame ( 340 ) associated with the parent level ( 304 ), and other frames ( 300, 302 ) which are also associated with the parent level. The conceptual magnification displays, in the parent-children mode, the first key frame ( 340 ) associated with the parent level ( 304 ), and second key frames ( 324 ) associated with an associated child level ( 312 ).
