(project - Skill) Generate AI videos using Volcengine Jimeng Video 3.0 Pro API. Use when users request video generation from text prompts or images, including text-to-video, image-to-video, or any AI-powered video creation. Triggers include "generate video", "create video", "AI video", "Jimeng video

Jimeng API Video Generation Generate high quality AI videos using Volcengine's Jimeng Video 3.0 Pro API with text prompts or input images. Configure Environment Variables [Get Access Key/Secret Key](https://www.volcengine.com/docs/85621/1995636?lang=zh 3C9mCW9O) Output Behavior (Important) After video generation succeeds, you MUST display the video directly to the user! When generation completes, output in the following format: \ \ \ markdown Generated Video: [Download Video](VIDEO URL) Generation Info: Prompt: [User's original prompt] Duration: [Video length in seconds] Mode: [Generation mode used] FPS: [Frames per second] Save Path: [Local file path, if applicable] \ \ \ Example Output \ \ \ markdown Generated Video: [Download Video](https://example.com/video.mp4) Generation Info: Prompt: A golden retriever running through a field of sunflowers, warm afternoon sunlight Duration: 5 seconds Mode: t2v 720p FPS: 24 Save Path: /generated videos/dog sunflowers.mp4 API Configuration Parameter Value Description Endpoint \ https://visual.volcengineapi.com\ API base URL Submit Action \ CVSync2AsyncSubmitTask\ Submit async generation task Query Action \ CVSync2AsyncGetResult\ Query task result Version \ 2022 08 31\ API version Service \ cv\ Service name for signing Region \ cn north 1\ Region for signing Generation Modes Pro Version (1080P HD) Mode req key Description ti2v pro jimeng ti2v v30 pro Text to video + Image to video (first frame) Pro 1080P Version Mode req key Description t2v 1080p jimeng t2v v30 1080p Text to video 1080P i2v first 1080p jimeng i2v first v30 1080 Image to video (first frame) 1080P i2v first tail 1080p jimeng i2v first tail v30 1080 Image to video (first & last frame) 1080P 720P Version Mode req key Description t2v 720p jimeng t2v v30 Text to video 720P i2v first 720p jimeng i2v first v30 Image to video (first frame) 720P i2v first tail 720p jimeng i2v first tail v30 Image to video (first & last frame) 720P i2v recamera 720p jimeng i2v recamera v30 Image to video (camera movement) 720P Command Line Options \ \ \ scripts/generate video.py PROMPT [OPTIONS] Arguments: PROMPT Text prompt for video generation (required) Options: mode MODE Generation mode (default: t2v 720p) Pro: ti2v pro 1080P: t2v 1080p, i2v first 1080p, i2v first tail 1080p 720P: t2v 720p, i2v first 720p, i2v first tail 720p, i2v recamera 720p duration SECS Video duration: 4, 5, 6, 8, 10 (default: 5) fps FPS Frames per second: 24, 25, 30 (default: 24) image URL Input image URL for image to video (first frame) tail image URL Tail image URL for first & last frame mode seed INT Random seed for reproducibility output PATH Download video to file json Output raw JSON response Environment Variables: VOLC ACCESSKEY Access Key ID (required) VOLC SECRETKEY Secret Access Key (required) JIMENG VIDEO API URL API endpoint (default: https://visual.volcengineapi.com) JIMENG VIDEO API TIMEOUT Request timeout seconds (default: 300) JIMENG VIDEO POLL INTERVAL Polling interval seconds (default: 5) JIMENG VIDEO MAX POLL ATTEMPTS Max polling attempts (default: 120) \ \ \ Video Specifications Duration Options Duration Use Case 4s Quick clips, social media 5s Default, general purpose 6s Short scenes 8s Medium length content 10s Longer narratives FPS Options FPS Use Case 24 Cinematic look (default) 25 PAL video standard 30 Smooth motion, NTSC standard Authentication This skill uses Volcengine IAM v4 signature authentication (HMAC SHA256). The signing process: 1. Build canonical request with headers: \ content type;host;x content sha256;x date\ 2. Calculate SHA256 hash of canonical request 3. Derive signing key: secret key → date → region → service → "request" 4. Sign the string to sign with derived key 5. Add \ Authorization\ header to request Reference: [HTTP请求示例](https://www.volcengine.com/docs/6444/1390583) Error Codes Code Message Description 10000 Success Request successful 50411 Pre Img Risk Not Pass Input image failed content check 50511 Post Video Risk Not Pass Output video failed content check 50412 Text Risk Not Pass Input text failed content check 50429 Request Has Reached API Limit Rate limit exceeded, retry later 50500 Internal Error Server error timeout Request timeout Increase JIMENG VIDEO API TIMEOUT Input/Output Limits Input Images (for image to video): Format: JPEG, PNG only Max size: 15MB per image Max resolution: 4096×4096 Output: Format: MP4 URL validity: 24 hours Generation time: 2 10 minutes depending on duration and mode Reference Documentation [Jimeng Video 3.0 Pro API Documentation](https://www.volcengine.com/docs/85621/1777001) [Jimeng Video 3.0 720P API](https://www.volcengine.com/docs/85621/1792710) [Jimeng Video 3.0 1080P API](https://www.volcengine.com/docs/85621/1792711) [HTTP Request Example](https://www.volcengine.com/docs/6444/1390583) [Volcengine Console](https://console.volcengine.com) [API Key Management](https://console.volcengine.com/iam/key manage/)
