Abstract: Provided are a video processing method and apparatus, an electronic device, a storage medium and a program product. The method includes steps described below. A to-be-processed video is acquired, and a first face key point of a first target object in the to-be-processed video is recognized, where the first face key point corresponds to a mask key point in a three-dimensional human face mask effect; and the three-dimensional human face mask effect is added to video frames of the to-be-processed video to obtain a target video, where the mask key point in the three-dimensional human face mask effect moves with the corresponding first face key point.

Abstract: Examples are provided relating to kinematic joint and chain physics tools for augmented reality implementations. One aspect includes a computing device for kinematic joint simulation, the computing device comprising a display and a processor coupled to a storage system that stores instructions, which, upon execution by the processor, cause the processor to present a chain simulation interface comprising a plurality of graphical control elements, each graphical control element configured to adjust at least one physical parameter, receive a selection from a user using the plurality of graphical control elements, update a chain model based on the received selection, and display and animate the updated chain model on the display using a physics engine during a kinematic motion simulation, wherein the chain model comprises a plurality of rigid body mesh models chained together by spring elements arranged in a tree configuration, to thereby form a rigged skeleton.
