Features

Wan 2.1 Text-to-Video 720p LoRA Ultra Fast

Wan 2.1 Text-to-Video 720p LoRA Ultra Fast is a lightning-fast text-to-video generation model with full LoRA support. Generate HD 720p videos from text descriptions in seconds, with custom styles and effects — perfect for rapid iteration and high-volume content creation.

Why It Stands Out

• Ultra-fast processing: Optimized for speed without sacrificing quality.
• LoRA support: Apply custom LoRA models for specific styles and effects.
• HD 720p output: Generate crisp 1280×720 videos with rich detail.
• 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

How to Use

1. Write a prompt describing the scene, action, and style you want. Use the Prompt Enhancer for AI-assisted optimization.
2. Add a negative prompt (optional) — specify elements to exclude.
3. Add LoRAs (optional) — select LoRA models and adjust their scale. Check recommended LoRAs for inspiration.
4. Set duration — choose 5 or 10 seconds.
5. Adjust parameters (optional) — fine-tune guidance scale and flow shift.
6. Click Run and wait for your video to generate.
7. Preview and download the result.

How to Use LoRA

LoRA (Low-Rank Adaptation) lets you apply custom styles without retraining the full model.

• Add LoRA: Enter the LoRA path and adjust the scale (0.0–1.0).
• Recommended LoRAs: Check the interface for suggested LoRAs with preview images (e.g., Fire effects).
• Scale adjustment: Higher scale means stronger style effect.

Best Use Cases

• Rapid Prototyping — Quickly test video concepts with custom styles.
• Visual Effects — Apply effects like fire, water, smoke with specialized LoRAs.
• Social Media Content — Create stylized videos for TikTok, Reels, and Shorts.
• Batch Processing — Generate multiple videos efficiently at scale.
• Creative Exploration — Experiment with different LoRA combinations.

Pro Tips for Best Quality

• Be detailed in your prompt — describe subject, action, environment, lighting, and mood.
• Use LoRAs to apply specific visual effects like fire, explosions, or weather.
• Start with LoRA scale around 0.7–1.0 and adjust based on results.
• Use negative prompts to reduce artifacts like blur, distortion, or unwanted motion.
• Check recommended LoRAs for proven style effects.
• Fix the seed when iterating to compare different LoRA combinations.

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.
