Abstract: The present disclosure provides a video generation method and apparatus, a device, and a storage medium. The method includes: playing a first video for prompting a video taking style on a video taking page in the form of a floating window, wherein the video taking page presents a taken image preview region for presenting a taken image in preview and a video taking control; recording, in response to a triggering operation on the video taking control, the taken image in the taken image preview region to generate a second video, wherein the second video and the first video have a same style. In this way, the second video is taken by playing, on the video taking page, the first video used for prompting the video taking style, so that an ordinary user can be guided to take a high-quality video, and the video taking experience of the user is improved.

Abstract: A foldable apparatus for supporting a flexible display screen includes a spindle assembly and two rotating components. At least one of the two rotating components is a first rotating component that includes a middle frame, a rotating holder, and a transmission structure. The rotating holder is rotatably connected to the spindle assembly. The middle frame is located at a side of the rotating holder away from the spindle assembly. The middle frame and the rotating holder is configured to slide in parallel. The transmission structure has one end connected to the spindle assembly and another end connected to the middle frame. The middle frame is configured to adhere to the flexible display screen. When the first rotating component rotates relative to the spindle assembly, the transmission structure moves relative to the rotating holder and drives the middle frame to slide in parallel relative to the rotating holder.

Abstract: A material having a first non-zero elastic modulus capable of reversibly changing the first non-zero elastic modulus to a second non-zero elastic modulus in response to a redox reaction occurring in the material. A method of producing a material that is reversibly cyclable between a first non-zero elastic modulus and a second non-zero elastic modulus, comprising: preparing a polymer comprising both crosslinks that do not depend on metal binding and functional groups capable of having oxidation-state specific binding constants to a metal ion; and doping the polymer with a solution containing the metal ion.
