Seedance excels at creating cinematic short clips with realistic motion, facial expressions, spatial audio, and complex camera movements. > **Data usage note**: This skill sends text prompts and image URLs 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 based on the model selected. --- ## Key Capabilities - **Text-to-Video** — Generate video clips from text descriptions with synchronized audio - **Image-to-Video** — Animate still images into dynamic video with motion and audio - **Native Audio Generation** — Dialogue, sound effects, and music generated jointly with video (not post-processed) - **Multi-Language Lip-Sync** — English, Chinese (including dialects), Japanese, Korean, Portuguese, Spanish, Indonesian - **Cinematic Camera Control** — Dolly-in, snap zoom, first-person POV, tripod lock, crane shots - **Multiple Styles** — Realistic, anime, 2D animation, steampunk, ink-wash, and more - **Resolution** — Up to 720p (Pro), 480p available - **Duration** — 5-12 seconds per clip --- ## Setup 1.

Birds chirping in the background, gentle wind rustling leaves.", "aspect_ratio": "16:9", "duration": 5, "resolution": "720p", "generate_audio": true }' # Returns: { "code": 200, "data": { "id": "prediction-id" } } # Step 2: Poll (every 5 seconds until "completed" or "succeeded") curl -s "https://api.atlascloud.ai/api/v1/model/prediction/{prediction-id}" \ -H "Authorization: Bearer $ATLASCLOUD_API_KEY" # Returns: { "code": 200, "data": { "status": "completed", "outputs": ["https://...video-url..."] } } # Step 3: Download curl -o output.mp4 "VIDEO_URL_FROM_OUTPUTS" ``` ### Image-to-Video Example ```bash curl -s -X POST "https://api.atlascloud.ai/api/v1/model/generateVideo" \ -H "Authorization: Bearer $ATLASCLOUD_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "model": "bytedance/seedance-v1.5-pro/image-to-video", "image": "https://example.com/portrait.jpg", "prompt": "The person slowly turns their head and smiles, camera gently zooms in", "aspect_ratio": "9:16", "duration": 5, "generate_audio": true }' ``` ### Fast Model Example (Quick Draft) ```bash curl -s -X POST "https://api.atlascloud.ai/api/v1/model/generateVideo" \ -H "Authorization: Bearer $ATLASCLOUD_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "model": "bytedance/seedance-v1.5-pro/text-to-video-fast", "prompt": "Ocean waves crashing on a rocky shore at sunset, seagulls flying overhead", "aspect_ratio": "16:9", "duration": 5, "generate_audio": true }' ``` ### Polling Logic - `processing` / `starting` / `running` → wait 5s, retry (Pro takes ~30-60s, Fast takes ~10-20s) - `completed` / `succeeded` → done, get URL from `data.outputs[]` - `failed` → error, read `data.error` ### Atlas Cloud MCP Tools (if available) If the Atlas Cloud MCP server is configured, use built-in tools: ``` atlas_quick_generate(model_keyword="seedance 1.5", type="Video", prompt="...") atlas_generate_video(model="bytedance/seedance-v1.5-pro/text-to-video", params={...}) atlas_get_prediction(prediction_id="...") ``` --- ## Implementation Guide 1. **Determine task type**: - Text-to-video: user describes a scene/action in text - Image-to-video: user provides an image to animate 2. **Choose model**: - **Pro** for final output, client-facing content, or quality-critical use - **Fast** for quick iteration, drafts, or budget-conscious use 3. **Extract parameters**: - Prompt: describe scene, action, camera movement, and audio cues - Aspect ratio: infer from context (social reel→9:16, YouTube→16:9, square→1:1, cinematic→21:9) - Duration: default 5s, up to 12s for longer scenes - Audio: enabled by default; disable with `generate_audio: false` if user only wants silent video - Camera: set `camera_fixed: true` for static/tripod shots 4. **Execute**: POST to generateVideo API → poll result → download MP4 5. **Present result**: show file path, offer to play ## Prompt Tips Seedance produces best results when prompts describe both visual and audio elements: - **Scene + Action**: "A chef flips a pancake in a busy kitchen, sizzling sounds and clattering pans" - **Camera direction**: "Camera slowly pans left to reveal...", "Close-up tracking shot of...", "First-person POV walking through..." - **Audio cues**: Include sound descriptions — "birds chirping", "rain on window", "jazz music playing softly" - **Dialogue**: For talking videos, include speech in quotes — "The narrator says: 'Welcome to our city'" - **Style**: "cinematic", "anime style", "documentary", "slow motion", "timelapse" - **Lip-sync**: For multi-language dialogue, specify the language — "A woman speaking Japanese says: 'こんにちは'" --- ## Coming Soon: Seedance 2.0 Seedance 2.0 is ByteDance's next-generation unified multimodal video generation system, currently in preview. When available on Atlas Cloud, this skill will be upgraded with: - **Higher resolution** — Expected support for 1080p and above - **Longer duration** — Extended video length beyond 12 seconds - **Multimodal references** — Video-to-video, audio-guided generation - **Director-level control** — Fine-grained manipulation of performance, lighting, shadow, and camera - **Enhanced motion stability** — Improved realism and coherence across longer clips The API workflow and parameter structure are expected to remain compatible. Model IDs will be updated when Seedance 2.0 becomes available — no configuration changes needed on your end.
