Playground

Hunyuan Video (t2v) is an advanced text-to-video model that generates high-quality videos from text prompts. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing.

Features

Transform your ideas into stunning videos with Hunyuan Video Text-to-Video. This state-of-the-art model from Tencent generates high-quality 720p videos directly from text descriptions — bringing your imagination to life with smooth motion and cinematic visuals.

Why It Stands Out

• Pure text-to-video generation: No source image required — simply describe your vision and watch it unfold.
• HD output: Generate crisp 1280×720 videos with rich detail and visual clarity.
• Prompt Enhancer: Built-in AI-powered prompt optimization helps craft better descriptions for improved results.
• Smooth motion: Advanced temporal modeling ensures natural, fluid movement across frames.
• Flexible sizing: Multiple aspect ratio options to fit your content needs.
• Reproducibility: Use the seed parameter to recreate exact results or explore variations.

Parameters

How to Use

1. Write a prompt describing the scene, characters, action, and style you want. Use the Prompt Enhancer for AI-assisted optimization.
2. Select size — choose the aspect ratio that fits your content.
3. Adjust inference steps — higher values may improve quality at the cost of speed.
4. Set a seed (optional) for reproducible results.
5. Click Run and wait for your video to generate.
6. Preview and download the result.

Best Use Cases

• Social Media Content — Create viral-worthy video clips for TikTok, Reels, and Shorts.
• Marketing & Advertising — Produce concept videos and promotional content without filming.
• Storytelling & Animation — Generate scenes for short films, music videos, or creative projects.
• Game & App Previews — Create cinematic trailers and gameplay concepts from descriptions.
• Educational Content — Visualize complex concepts and scenarios for learning materials.

Pro Tips for Best Quality

• Be detailed in your prompt — describe subject, action, environment, lighting, mood, and camera movement.
• Include style keywords like “cinematic,” “realistic,” “anime,” or “futuristic” to guide the aesthetic.
• Start with lower inference steps for quick previews, then increase for final renders.
• Fix the seed when iterating to compare the effect of different prompt adjustments.
• Keep prompts focused — overly complex descriptions may dilute the output quality.

Notes

• Processing time varies based on current queue load.
• Please ensure your prompts comply with content guidelines.
