Features
HunyuanVideo
HunyuanVideo is an advanced image-to-video generation model that can create high-quality videos from text descriptions. It features a comprehensive framework that integrates image-video joint model training and efficient infrastructure for large-scale model training and inference.
Model Description
This model is trained on a spatial-temporally compressed latent space and uses a large language model for text encoding. According to professional human evaluation results, HunyuanVideo outperforms previous state-of-the-art models in terms of text alignment, motion quality, and visual quality.
Key features
- 🎨 High-quality video generation from text descriptions
- 📐 Support for various aspect ratios and resolutions
- ✍️ Advanced prompt handling with a built-in rewrite system
- 🎯 Stable motion generation and temporal consistency

"prompt": "A pale vampire woman slowly walks to a candlelit window, her crimson eyes glowing in the dark. She lifts one hand and gently taps her long, sharp nails against the glass. Her expression shifts from seductive to dangerous. Outside, bats flutter past a glowing full moon, casting flickering shadows across her face. The candlelight flickers, reflecting in her eyes as she stares into the night",
