Wan 2.1 T2V 480p Ultra Fast — wavespeed-ai/wan-2.1/t2v-480p-ultra-fast
Wan 2.1 T2V 480p Ultra Fast is a text-to-video model optimized for speed and iteration. Write a prompt, pick a duration, and generate a short 480p video quickly—ideal for rapid concept testing, storyboard previews, and high-volume variations.
What it’s good at
- Text-to-Video (T2V): generate video directly from a prompt
- Ultra-fast generation: built for quick iteration and high-throughput workflows
- 480p output: lightweight resolution for draft-quality previews and batch runs
- Creative control knobs: guidance scale, steps, flow shift, seed
Common use cases
- Storyboard & pre-visualization: turn scripts into short motion sketches before committing to higher-cost renders
- Marketing concept exploration: generate multiple variants of the same idea (camera, action, mood) and pick winners fast
- Motion style prototyping: test different motion intensity settings for pacing, dynamism, and scene continuity
- Batch ideation: generate many drafts to explore composition, timing, and cinematic language
Inputs
- Prompt (required): describe subject, action, setting, lighting, camera movement, and mood
- Negative prompt (optional): list artifacts to avoid (blur, jitter, distortion, low quality, inconsistent motion)
Parameters (Playground / API)
- Size: 832×480 (480p)
- Duration: 5s or 10s
- Num inference steps: higher can improve stability/detail but costs more time
- Guidance scale: higher follows the prompt more strictly; too high may reduce natural motion
- Flow shift: adjusts motion feel and temporal dynamics
- Seed: use a fixed value for reproducibility; use -1 for random
Pricing
| Output | Duration | Price per video | Price per second |

| 480p T2V Ultra Fast | 5s | $0.125 | $0.0250/s |
| 480p T2V Ultra Fast | 10s | $0.1875 | $0.01875/s |
Prompting tips (T2V)
- Write like a director: Subject + Action + Scene + Camera + Style
- Use concrete motion verbs: walks, turns, reaches, leans, spins, drifts, stops
- Add camera language to make it feel like “video,” not “animated still”: slow dolly-in, handheld, orbit, pan left, tilt up, rack focus
- Keep negative prompts short and practical: blurry, jittery, flicker, distorted, low quality, inconsistent motion
