The present disclosure provides a video blending method, apparatus, electronic device and readable storage medium, and relates to computer vision technologies. A specific implementation solution is as follows: obtaining a predicted 3D face mesh of a facial image in each video frame images of the user video according to each video frame image of a user video and each video frame image of a template video; obtaining a predicted texture of the predicted 3D face mesh according to a user texture of a user 3D face mesh of the facial image in each video frame image of the user video and a template texture of a template 3D face mesh of the facial image in each video frame image of the template video; obtaining a rendered facial image of the predicted 3D face mesh according to the predicted 3D face mesh, the predicted texture and user face posture, and template face posture; performing blending processing for the rendered facial image and each video frame image of the template video to obtain a blended video frame image after the blending; performing synthesis processing for the blended video frame image to obtain a blended video.
