The Vidu: Video Extension workflow is designed to seamlessly extend video content while enhancing its resolution to 1080p. This workflow leverages the Vidu Q2 model, which is specifically tailored for video extension tasks. By utilizing nodes such as ViduExtendVideoNode and LoadVideo, users can upload an existing video and extend its duration by up to 7 seconds. The workflow also includes nodes like GetVideoComponents and SaveVideo to dissect and reassemble the video content efficiently. This process is particularly useful for creators looking to enhance short video clips without compromising on quality. Technically, the workflow dissects the video into frames, applies the Vidu model to generate additional frames, and then reconstructs the extended video. The use of ImageFromBatch and GetImageSize nodes ensures that the output maintains a high resolution, making it ideal for professional video projects.
