Abstract: The present disclosure provides a method and device for processing a video. The method includes: determining a special effect video frame of a video, where a target feature area of the special effect video frame includes a preset special effect map; and modifying a display effect of the special effect map upon determining that a shielded area exists in the target feature area.

Abstract: A video rendering method is provided. The method includes acquiring a first video which is to be rendered and a material video for rendering the first video, wherein the material video is obtained by splicing and combining at least two video effects, and each of the video effects comprises a plurality of material pictures. The method further includes disassembling a plurality of material blocks from the material video, each of the material blocks being obtained by sequentially arranging a plurality of material pictures belonging to a same video effect, determining target positions of the material blocks in a video frame of the first video, and acquiring a second video by superimposing the material blocks on the target position of the video frame to complete video rendering.

Abstract: A hair rendering method includes acquiring a target video containing hair information, and selecting a target image frame from image frames of the target video, acquiring a texture image of the target image frame, wherein the texture image is an image in a texture format which records motion states and state change information of one or more pixel points in the target image frame. The method further includes acquiring a first target motion state and target state change information of a first target particle region from the texture image; determining a second target motion state of the first target particle region in a next image frame according to the first target motion state and the target state change information, and rendering the hair region by updating a motion state in the texture image according to the second target motion state.

Abstract: Embodiments of the present disclosure provide a method for adding a special effect to a video, an electronic device and a storage medium. First portrait edge information of a first frame is determined based on the portrait foregrounds of the first frame and a previous frame. A fluctuation offset based on a playback time and a fluctuation parameter is added to the first portrait edge information to obtain second portrait edge information. The second portrait edge information is superimposed on the first frame to obtain a second frame having the special effect.

Abstract: A method for processing a face image. The method includes: detecting face key points in the face image; determining a face key point grid of the face image based on the face key points, wherein the face key point grid comprises a plurality of grid areas defined by connection lines between the face key points; generating a special effect face image by adding a special-effect material to a grid area in the face key point grid, wherein the special-effect material is pre-designed for representing a specified image effect; determining a processed face image by adjusting a face contour in the special effect face image based on preset liquify filter parameters, wherein the preset liquify filter parameters are determined based on the specified image effect; the processed face image has the specified image effect.

Abstract: A method electronic device and storage medium for processing an image are provided. The method includes: receiving an instruction for a preset fly-away special effect; creating a facial grid and facial feature grids in the image to be processed; determining a facial image in an image region covered by the facial grid; setting a pixel value of each pixel in the facial image to a target pixel value; extracting facial feature images from an image region covered by the facial feature grids; and obtaining a target image by mapping the facial feature images onto the facial image based on a preset triangular mapping algorithm and a preset offset.
