Released on October 15, 2026, it introduces advanced video generation capabilities that give creators more control over their content. Users can guide video creation with multiple reference frames, helping maintain visual consistency, character appearance, and scene details. The model also focuses on realistic movements, cinematic camera angles, and synchronized audio.
