Abstract: A special-effect display method and apparatus, and a device and a medium are provided. The method includes: acquiring a photographed video image; determining position information of a recognition object on the basis of the photographed video image, and performing drawing according to the position information of the recognition object, so as to obtain a trajectory record image; performing superimposition processing on the trajectory record image and a preset special-effect material image, so as to obtain cell special-effect images; and performing transformation processing on the cell special-effect images, so as to generate a target special-effect image, and adding the target special-effect image to the photographed video image for displaying, wherein the target special-effect image is an image formed by combining a plurality of cell special-effect images.
