Abstract: The present disclosure provides a video generation method, an apparatus, a device and a medium, and the method includes: acquiring background images; acquiring an image to be segmented comprising a target object; performing image segmentation for the target object on the image to be segmented to obtain a contour image corresponding to the target object; using the contour image as a foreground image of a target display video; and cyclically flipping the background images, and generating the target display video by fusing the foreground image and the background images, in which the background images are being cyclically flipped in the target display video.
