Describe a scene, camera angle, lighting, and mood. Happy Horse renders a 1080p clip in approximately 38 seconds with only 8 denoising steps.
Image-to-Video Animation
Upload a still frame as the starting point. The model adds natural motion, camera movement, and depth — keeping the original composition intact.
Joint Audio-Video Synthesis
