The present disclosure provides a video generation method, an apparatus, a system, a device and a storage medium. The method is applied to a video generation system, and the video generation system includes a first client and at least one second client. Specifically, the method includes: firstly, the first client creates a first virtual room and sets a target capturing effect for the first virtual room; then, the second client acquires a first video added with the target capturing effect after receiving a notification message that a current user has successfully joined the first virtual room, and uploads the first video to the first virtual room. Further, the first client acquires a target video from the first virtual room and generates a target result video based on the target video, and the target video includes the first video.

The present invention relates to a catalyst component suitable for olefin (co)polymerization, which comprises an aluminoxane supported on magnesium halide and contains more than 5% by weight of aluminum. The catalyst component according to the present invention is obtained by contacting an aluminoxane compound and a magnesium compound in the presence of a multifunctional organic compound. The catalyst comprising said component and metallocene shows good activity and consumes less amount of aluminoxane in the process of olefin polymerization. The polymer prepared by using said catalyst has an improved particle morphology and a narrow particle distribution.
