Vidu — AI Video Generation by Shengshu AI

Generate AI videos using Vidu Q3-Pro and Vidu 2.0 — featuring text-to-video, image-to-video, reference-based generation, and start-end frame interpolation with up to 1080p resolution, anime style support, and synchronized audio generation.

Vidu Q3-Pro is the latest flagship model with cinematic motion quality, smooth animation, optional audio/BGM generation, and multiple style modes (general/anime). Vidu 2.0 adds specialized capabilities including reference-to-video (character-consistent generation) and start-end-to-video (keyframe interpolation).

Data usage note: This skill sends text prompts, image URLs, and video data to the Atlas Cloud API (api.atlascloud.ai) for video generation. No data is stored locally beyond the downloaded output files. API usage incurs charges per second based on the model selected.

Setup

1. 1. Sign up at https://www.atlascloud.ai
2. Console → API Keys → Create new key
3. Set env: INLINECODE1

The API key is tied to your Atlas Cloud account and its pay-as-you-go balance. All usage is billed to this account. Atlas Cloud does not currently support scoped keys — the key grants access to all models available on your account.

• - processing / starting / running → wait 5s, retry (typically takes ~60-120s)
• INLINECODE40 / succeeded → done, get URL from INLINECODE42
• INLINECODE43 → error, read INLINECODE44

Implementation Guide

1. 1. Determine task type:

- Text-to-video: user describes a scene/action in text → Q3-Pro T2V - Image-to-video: user provides an image to animate → Q3-Pro I2V or 2.0 I2V - Start-end interpolation: user provides two keyframes → 2.0 Start-End - Character-consistent video: user provides reference images → 2.0 / Q1 Reference - Anime content: user wants anime style → Q3-Pro with style="anime"

1. 2. Choose model:

- Q3-Pro (recommended): Latest generation, best quality, audio/BGM, up to 1080p, anime support - 2.0 Image-to-Video: Budget option at $0.075/video for simple animations - 2.0 Start-End: Unique keyframe interpolation capability - 2.0 Reference: Character-consistent generation from reference images ($0.2/video) - Q1 Reference: Highest quality reference-to-video ($0.4/video)

1. 3. Extract parameters:

- Prompt: describe scene, action, camera movement - Style: general (realistic) or anime - Resolution: 540p for drafts, 720p default, 1080p for final output - Duration: Q3-Pro supports flexible durations; 2.0 supports 4 or 8 seconds - Movement amplitude: small for subtle motion, large for dynamic action - Audio: enabled by default on Q3-Pro, set generate_audio=false to disable

1. 4. Execute: POST to generateVideo API → poll result → download MP4

1. 5. Present result: show file path, offer to play

Prompt Tips

• - Scene + Action: "A chef flips a pancake in a busy kitchen, steam rising from the pan"
• Camera direction: "Camera slowly pans left...", "Close-up tracking shot of...", "Aerial view..."
• Anime style: Use style: "anime" + anime-specific prompts: "An anime warrior charges forward, energy aura glowing..."
• Movement amplitude: Use small for talking heads/subtle scenes, large for action/sports
• Start-End: Provide visually similar frames for smooth interpolation; dramatic differences work for morphing effects
• Reference: Provide clear, well-lit character references from multiple angles for best consistency
