Wan 2.1 Text-to-Video 720p Ultra Fast
Wan 2.1 Text-to-Video 720p Ultra Fast is a lightning-fast text-to-video generation model optimized for speed and efficiency. Generate HD 720p videos from text descriptions in seconds — perfect for rapid iteration, previews, and high-volume video creation.
Why It Stands Out
- Ultra-fast processing: Optimized for speed without sacrificing quality.
- HD 720p output: Generate crisp videos in landscape (1280×720) or portrait (720×1280).
- Prompt Enhancer: Built-in AI-powered prompt optimization for better results.
- Negative prompt support: Exclude unwanted elements for cleaner outputs.
- Fine-tuned control: Adjust guidance scale and flow shift for precise results.
- Reproducibility: Use the seed parameter to recreate exact results.
Parameters
| Parameter | Required | Description |
|---|---|---|
| prompt | Yes | Text description of the video you want to generate. |
| negative_prompt | No | Elements to avoid in the output. |
| size | No | Output resolution: 1280×720 or 720×1280 (default: 1280×720). |
| num_inference_steps | No | Quality/speed trade-off (default: 30). |
| duration | No | Video length: 5 or 10 seconds (default: 5). |
| guidance_scale | No | Prompt adherence strength (default: 5). |
| flow_shift | No | Motion flow control (default: 5). |
| seed | No | Set for reproducibility; -1 for random. |
How to Use
- Write a prompt describing the scene, action, and style you want. Use the Prompt Enhancer for AI-assisted optimization.
- Add a negative prompt (optional) — specify elements to exclude.
- Select size — choose landscape (1280×720) or portrait (720×1280).
- Set duration — choose 5 or 10 seconds.
- Adjust parameters (optional) — fine-tune guidance scale and flow shift.
- Click Run and wait for your video to generate.
- Preview and download the result.
Best Use Cases
- Rapid Prototyping — Quickly test video concepts before committing to higher quality models.
- Batch Processing — Generate multiple videos efficiently at scale.
- Content Previews — Create quick previews for client approval.
- Social Media Content — Produce videos for TikTok, Reels, and Shorts.
- Creative Exploration — Experiment with different prompts at minimal cost.

Pro Tips for Best Quality
- Be detailed in your prompt — describe subject, action, environment, lighting, and mood.
- Include camera movement keywords like "tracking shot," "close-up," or "wide angle."
- Use negative prompts to reduce artifacts like blur, distortion, or unwanted motion.
- Choose portrait (720×1280) for mobile-first platforms like TikTok.
- Start with Ultra Fast for testing, then upgrade to standard models for final delivery.
Notes
- Processing time is optimized for speed — expect quick turnaround.
- Higher num_inference_steps produces better quality but increases generation time.
- Please ensure your prompts comply with content guidelines.
