Seedance Video Generation
Generate AI videos using ByteDance Seedance models via the Volcengine Ark API.
Prerequisites
The user must set the ARK_API_KEY environment variable. You can set it by running: export ARK_API_KEY="your-api-key-here" Base URL: https://ark.cn-beijing.volces.com/api/v3

Execution (Recommended: Python CLI Tool)
A Python CLI tool is provided at ~/.claude/skills/seedance-video/seedance.py for robust execution with proper error handling, automatic retries, and local image base64 conversion. Prefer using this tool over raw curl commands.
Quick Examples with Python CLI

Step 1: Create Video Generation Task
Determine the generation mode based on user input, then call the API. Mode A: Text-to-Video TASK_RESULT=$(curl -s -X POST "https://ark.cn-beijing.volces.com/api/v3/contents/generations/tasks" \ -H "Content-Type: application/json" \ -H "Authorization: Bearer $ARK_API_KEY" \ -d '{ "model": "doubao-seedance-1-5-pro-251215", "content": [ { "type": "text", "text": "YOUR_PROMPT_HERE" } ], "ratio": "16:9", "duration": 5, "resolution": "720p", "generate_audio": true }') TASK_ID=$(echo "$TASK_RESULT" | python3 -c "import sys,json; print(json.load(sys.stdin)['id'])") echo "Task created: $TASK_ID" Mode B: Image-to-Video (First Frame) The user provides one image as the first frame. The image can be a URL or local file path (convert to base64). With image URL: TASK_RESULT=$(curl -s -X POST "https://ark.cn-beijing.volces.com/api/v3/contents/generations/tasks" \ -H "Content-Type: application/json" \ -H "Authorization: Bearer $ARK_API_KEY" \ -d '{ "model": "doubao-seedance-1-5-pro-251215", "content": [ { "type": "text", "text": "YOUR_PROMPT_HERE" }, { "type": "image_url", "image_url": { "url": "IMAGE_URL_HERE" }, "role": "first_frame" } ], "ratio": "adaptive", "duration": 5, "resolution": "720p", "generate_audio": true }') TASK_ID=$(echo "$TASK_RESULT" | python3 -c "import sys,json; print(json.load(sys.stdin)['id'])") echo "Task created: $TASK_ID" With local image file (convert to base64): IMG_PATH="/path/to/image.png" IMG_EXT="${IMG_PATH##*.}" IMG_EXT_LOWER=$(echo "$IMG_EXT" | tr '[:upper:]' '[:lower:]') IMG_BASE64=$(base64 < "$IMG_PATH" | tr -d '\n') IMG_DATA_URL="data:image/${IMG_EXT_LOWER};base64,${IMG_BASE64}" TASK_RESULT=$(curl -s -X POST "https://ark.cn-beijing.volces.com/api/v3/contents/generations/tasks" \ -H "Content-Type: application/json" \ -H "Authorization: Bearer $ARK_API_KEY" \ -d '{ "model": "doubao-seedance-1-5-pro-251215", "content": [ { "type": "text", "text": "YOUR_PROMPT_HERE" }, { "type": "image_url", "image_url": { "url": "'"$IMG_DATA_URL"'" }, "role": "first_frame" } ], "ratio": "adaptive", "duration": 5, "resolution": "720p", "generate_audio": true }') TASK_ID=$(echo "$TASK_RESULT" | python3 -c "import sys,json; print(json.load(sys.stdin)['id'])") echo "Task created: $TASK_ID" Mode C: Image-to-Video (First + Last Frame) Requires two images. Supported by: Seedance 1.5 Pro, 1.0 Pro, 1.0 Lite I2V. TASK_RESULT=$(curl -s -X POST "https://ark.cn-beijing.volces.com/api/v3/contents/generations/tasks" \ -H "Content-Type: application/json" \ -H "Authorization: Bearer $ARK_API_KEY" \ -d '{ "model": "doubao-seedance-1-5-pro-251215", "content": [ { "type": "text", "text": "YOUR_PROMPT_HERE" }, { "type": "image_url", "image_url": { "url": "FIRST_FRAME_IMAGE_URL" }, "role": "first_frame" }, { "type": "image_url", "image_url": { "url": "LAST_FRAME_IMAGE_URL" }, "role": "last_frame" } ], "ratio": "adaptive", "duration": 5, "resolution": "720p", "generate_audio": true }') TASK_ID=$(echo "$TASK_RESULT" | python3 -c "import sys,json; print(json.load(sys.stdin)['id'])") echo "Task created: $TASK_ID" Mode D: Reference Image-to-Video (Seedance 1.0 Lite I2V only) Provide 1-4 reference images. Use [图1], [图2] in prompt to reference specific images. TASK_RESULT=$(curl -s -X POST "https://ark.cn-beijing.volces.com/api/v3/contents/generations/tasks" \ -H "Content-Type: application/json" \ -H "Authorization: Bearer $ARK_API_KEY" \ -d '{ "model": "doubao-seedance-1-0-lite-i2v-250219", "content": [ { "type": "text", "text": "[图1]的人物在跳舞" }, { "type": "image_url", "image_url": { "url": "REF_IMAGE_URL_1" }, "role": "reference_image" } ], "ratio": "16:9", "duration": 5, "resolution": "720p" }') TASK_ID=$(echo "$TASK_RESULT" | python3 -c "import sys,json; print(json.load(sys.stdin)['id'])") echo "Task created: $TASK_ID"
Step 2: Poll for Task Completion
Video generation is asynchronous. Poll the task status until it completes. echo "Waiting for video generation to complete..." while true; do STATUS_RESULT=$(curl -s -X GET "https://ark.cn-beijing.volces.com/api/v3/contents/generations/tasks/${TASK_ID}" \ -H "Authorization: Bearer $ARK_API_KEY") STATUS=$(echo "$STATUS_RESULT" | python3 -c "import sys,json; print(json.load(sys.stdin)['status'])") if [ "$STATUS" = "succeeded" ]; then echo "Video generation succeeded!" VIDEO_URL=$(echo "$STATUS_RESULT" | python3 -c "import sys,json; print(json.load(sys.stdin)['content']['video_url'])") echo "Video URL: $VIDEO_URL" break elif [ "$STATUS" = "failed" ]; then ERROR_MSG=$(echo "$STATUS_RESULT" | python3 -c "import sys,json; d=json.load(sys.stdin); print(d.get('error',{}).get('message','Unknown error'))" 2>/dev/null || echo "Unknown error") echo "Video generation failed: $ERROR_MSG" break elif [ "$STATUS" = "expired" ]; then echo "Video generation task expired." break else echo "Status: $STATUS - still processing..." sleep 15 fi done
Step 3: Download and Open Video
OUTPUT_PATH="$HOME/Desktop/seedance_video_$(date +%Y%m%d_%H%M%S).mp4" curl -s -o "$OUTPUT_PATH" "$VIDEO_URL" echo "Video saved to: $OUTPUT_PATH" open "$OUTPUT_PATH"

Query Task Status

Generate Consecutive Videos (Using Last Frame)
Set return_last_frame: true on the first task, then use the returned last_frame_url as the first frame of the next task. # Get last frame URL from completed task LAST_FRAME_URL=$(curl -s -X GET "https://ark.cn-beijing.volces.com/api/v3/contents/generations/tasks/${TASK_ID}" \ -H "Authorization: Bearer $ARK_API_KEY" | python3 -c "import sys,json; print(json.load(sys.stdin)['content']['last_frame_url'])") # Use it as first frame for the next video # ... (use Mode B with LAST_FRAME_URL as the image URL)
Draft Mode (Seedance 1.5 Pro)
Generate a cheap preview first, then produce the final video if satisfied: # Step 1: Create draft DRAFT_RESULT=$(curl -s -X POST "https://ark.cn-beijing.volces.com/api/v3/contents/generations/tasks" \ -H "Content-Type: application/json" \ -H "Authorization: Bearer $ARK_API_KEY" \ -d '{ "model": "doubao-seedance-1-5-pro-251215", "content": [ { "type": "text", "text": "YOUR_PROMPT_HERE" } ], "draft": true, "resolution": "480p" }') DRAFT_TASK_ID=$(echo "$DRAFT_RESULT" | python3 -c "import sys,json; print(json.load(sys.stdin)['id'])") # Step 2: After draft succeeds, generate final video from draft FINAL_RESULT=$(curl -s -X POST "https://ark.cn-beijing.volces.com/api/v3/contents/generations/tasks" \ -H "Content-Type: application/json" \ -H "Authorization: Bearer $ARK_API_KEY" \ -d '{ "model": "doubao-seedance-1-5-pro-251215", "content": [ { "type": "draft_task", "draft_task": { "id": "'"$DRAFT_TASK_ID"'" } } ], "resolution": "720p" }')

Rules
Always check that ARK_API_KEY is set before making API calls: [ -z "$ARK_API_KEY" ] && echo "Error: ARK_API_KEY not set" && exit 1 Default to Seedance 1.5 Pro (doubao-seedance-1-5-pro-251215) unless user requests a specific model. Default to 720p, 16:9, 5 seconds, with audio for text-to-video. Default to adaptive ratio for image-to-video (auto-adapts to the input image). Poll interval: 15 seconds between status checks. Video URLs expire in 24 hours - always download immediately after generation. Task history is kept for 7 days only. For local image files, convert to base64 data URL format before sending. Always show the user the task ID so they can check status later. When generation fails, display the error message clearly and suggest possible fixes.
