HappyHorse 1.1 is the latest release of Alibaba's production-grade video generation model, now available in ComfyUI as a Partner Node. It is engineered for real-world creative production: short episodic series, e-commerce commercials, brand marketing content, and game cutscenes. A standout feature is **native synchronized audio generation**: HappyHorse 1.1 produces dialogue, sound effects, and background music in a single render pass, with audio tightly bound to the visual timeline. There are no extra audio steps. Version 1.1 targets five core production-critical capabilities: dynamic expressive motion, consistent character rendering, reliable prompt adherence, stable text rendering, and authentic cinematic framing. ## What HappyHorse 1.1 is good at * **Native audio-video sync**: Dialogue, SFX, and background music in one pass (no extra steps) * **Three creation paths**: Text-to-Video (T2V), Image-to-Video (I2V), Reference-to-Video (R2V) * **Multi-image R2V**: Up to **9 reference images** per generation with preserved identity * **Multi-character consistency**: Multiple character references stay distinct with no visual cross-contamination * **Character × scene separation**: Feed characters and scenes as independent references; characters stay consistent as the background changes * **Long-context prompts**: Handles prompts beyond 2,500 characters; a single prompt can describe 6–8 consecutive scenes with the model autonomously allocating time and switching camera angles * **Cinematic language**: Full support for shot-reverse-shot, tracking shot, and cohesive transitions/pacing between shots * **Flexible output**: 720p and 1080p, 3–15 seconds, aspect ratios 16:9 / 9:16 / 1:1 / 4:3 / 3:4 / 21:9 and more * **Production-ready visuals**: Fixes shiny skin and over-sharpening issues from v1.0 for natural-looking close-ups and series content ## Use it in ComfyUI Run the text-to-video, image-to-video, and reference-to-video workflows in ComfyUI, locally or on Comfy Cloud
