The present disclosure relates to a method and apparatus for generating a video, an electronic device, and a computer program product. The method includes obtaining a visual token for generating an image frame in the video. The method further includes obtaining a control token for constraining position information of an object in the image frame. In addition, the method also includes generating the image frame in the video based on the visual token and the control token, where the object in the image frame satisfies the position information.

Method and apparatus for generating video, electronic device, and computer program product

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.
