In a video special effects apparatus for processing an input video, mapping data representative of the destination position after conversion of each pixel of the input video data are stored in a memory (5) based upon a write address signal to which is added an offset which becomes larger with lapse of time, and a video image conversion is applied to the input video signal based on mapping data which are read from the memory (5) in response to a read address signal. <IMAGE>
