Why Choose This?

• Fast generation Pro architecture delivers quick results for rapid prototyping and iteration.

• Text-driven video creation Turn scene descriptions into dynamic video clips with controllable motion and style.

• Multiple resolutions Choose from 540p, 720p, or 1080p to balance quality and cost.

• Style presets Select a visual style preset to better match your creative direction.

• Motion control Adjust movement_amplitude to control the intensity of motion in the video.

• Optional audio generation Generate synchronized audio and background music for more complete video output.

Parameters

How to Use

1. Write your prompt — describe the scene, action, camera feel, and visual style you want.
2. Choose a style — select a preset that matches your creative direction.
3. Set resolution — use 540p for speed, 720p for balance, or 1080p for higher quality.
4. Set duration — choose the desired video length.
5. Adjust motion (optional) — control movement intensity with movement_amplitude.
6. Configure audio (optional) — toggle generate_audio and bgm if you want sound in the output.
7. Set a seed (optional) — use a fixed seed for more reproducible generations.
8. Submit — run the model and download the generated video.

Example Prompt

A cinematic night drive through a neon-lit city, light rain reflecting on the road, smooth forward camera motion, moody atmosphere, realistic lighting, subtle environmental motion

Pricing

Pricing is based on duration and resolution.

Example Costs

Billing Rules

• Pricing scales linearly with duration
• 540p costs $0.25 per 5 seconds
• 720p costs 2.5× the 540p base rate
• 1080p costs 3× the 540p base rate
• style, movement_amplitude, generate_audio, bgm, and seed do not affect pricing
• Off-peak pricing may be available separately through the provider

Best Use Cases

• Social media content — Create engaging short-form videos for Reels, Shorts, and similar formats.
• Rapid prototyping — Quickly visualize creative concepts before committing to production.
• Marketing and ads — Generate promotional clips with synchronized audio and motion.
• Storytelling — Bring narrative scenes to life with motion, mood, and background music.
• Game and app assets — Create animated content for interactive experiences and presentations.

Pro Tips

• Be specific in your prompt about scene, action, lighting, and camera movement.
• Start with 540p for rapid iteration, then switch to 720p or 1080p for final-quality output.
• Use a fixed seed when you want more consistent variations.
• Enable bgm for atmospheric content, and disable it when you plan to add custom audio later.
• Lower movement_amplitude for calmer scenes, and raise it for more energetic or dramatic motion.

Notes

• prompt is the only required field.
• duration supports 1–16 seconds for Q3 Pro.
• Higher resolution increases both output quality and total cost.
• Native Vidu documentation uses the audio flag, while this WaveSpeed schema exposes generate_audio and bgm.
• seed = -1 means a random seed will be used.
