ByteDance Seedance V1 Pro — Text-to-Video 720p
Seedance V1 Pro Text-to-Video 720p is ByteDance’s premium text-to-video generation model that creates cinematic-quality videos from text descriptions. Generate stunning 720p HD videos with smooth motion, flexible aspect ratios, and durations up to 12 seconds.
Why It Stands Out
- Premium quality: Pro-level output with exceptional detail, motion, and visual fidelity.
- Flexible duration: Generate videos from 2 to 12 seconds long.
- Prompt Enhancer: Built-in AI-powered prompt optimization for better results.
- Multiple aspect ratios: Choose from 21:9, 16:9, 4:3, 1:1, 3:4, or 9:16.
- Camera control: Option to fix camera position for stable, static shots.
- Reproducibility: Use the seed parameter to recreate exact results.
Parameters
| Parameter | Required | Description |
|---|---|---|
| prompt | Yes | Text description of the video you want to generate. |
| aspect_ratio | No | Output aspect ratio: 21:9, 16:9, 4:3, 1:1, 3:4, 9:16 (default: 16:9). |
| duration | No | Video length: 2–12 seconds (default: 5). |
| camera_fixed | No | Fix camera position for stable shots. |
