YouTube introduced a significant update to its Shorts feature this Thursday. By integrating Google's DeepMind Veo video generation model, the Dream Screen functionality now supports AI video background generation, allowing for 1080p HD video output, greatly enhancing creators' short video production. The application of this technology is extremely simple and intuitive. Creators just need to open the Shorts camera, click the 'Green Screen' icon, select the 'Dream Screen' feature, and input the desired scene.
