| description | Generate videos using TensorsLab's AI video generation models. Supports text-to-video and image-to-video generation with automatic prompt enhancement, progress tracking, and local file saving. Use for generating videos from text descriptions, animating static images, creating cinematic content, and various aspect ratios. Requires TENSORSLAB_API_KEY environment variable. Video generation takes several minutes. |
TensorsLab Video Generation
Overview
This skill enables AI-powered video generation through TensorsLab's API, supporting both text-to-video and image-to-video workflows. Video generation is a time-intensive process - tasks typically take several minutes to complete.
Authentication Check
Before any video generation, verify the API key is configured:
[ -n "$TENSORSLAB_API_KEY" ] && echo "✅ API key is set" || echo "❌ TENSORSLAB_API_KEY is not set"
If not set, display this friendly message:
您好！要生成高质量的内容，您需要先进行简单的配置：
1. 访问 https://tensorslab.tensorslab.com/ 登录并订阅。
2. 在控制台中获取您的专属 API Key。
3. 将其保存为环境变量：
- Windows (PowerShell): $env:TENSORSLAB_API_KEY="您的Key"
- Mac/Linux: export TENSORSLAB_API_KEY="您的Key"
Models
| Model | Description | Best For | Max Duration |
|---|
| seedancev2 | Latest, highest quality | General purpose, cinematic content | 15s |
| seedancev15pro | Pro quality | High-end productions | 10s |
| seedancev1profast | Fast generation | Quick previews | 10s |
| seedancev1 | Standard lite | Basic videos | 10s |
Default: seedancev1profast
Workflow
1. Text-to-Video Generation
User request: "做一段 10 秒钟横屏的宇宙飞船穿梭星际的视频"
Agent processing:
- Extract parameters:
duration=10, ratio="16:9"
- Enhance prompt with cinematic details, camera movements, scene descriptions
- Call API with enriched prompt
- Monitor progress with heartbeat updates (every 60 seconds)
- Download to
./tensorslab_output/
Example enhanced prompt:
Cinematic wide shot of a spaceship rapidly flying through space, passing glowing
nebulae and distant stars, lens flares, dramatic camera movement, epic scale,
movie-quality visual effects, smooth 24fps motion
2. Image-to-Video Generation
User request: "让这张人物合影 family.jpg 动起来" or "让风景照动起来"
Agent processing:
- Extract image file paths (1-2 images supported)
- Enhance prompt with motion instructions
- Monitor progress with heartbeat updates
- Download results
Parameters for image-to-video:
sourceImage: Array of image files (1-2 images max)imageUrl: Comma-separated URLs of source imagesprompt: Description of desired motion/animation
3. Resolution and Aspect Ratio
Aspect ratios:
9:16 - Vertical (TikTok, Reels, Shorts) - default16:9 - Horizontal (YouTube, standard video)- Other ratios available depending on model
Resolutions:
480p - SD quality, faster generation720p - HD quality - default1080p - Full HD1440p - 2K quality (seedancev2 only)
4. Duration Options
- seedancev2: 5-15 seconds
- Other models: 5-10 seconds
Longer videos take proportionally more time to generate.
5. Special Features (seedancev2 only)
| Feature | Parameter | Description |
|---|
| Audio Generation | generate_audio=1 | Generate soundtrack with video |
| Last Frame | return_last_frame=1 | Also return final frame as image |
Progress Tracking
Video generation takes several minutes. Keep users informed:

Using the Script
依赖：脚本需要 requests 库，首次使用前执行：
pip install requests
Execute the Python script directly:
python scripts/tensorslab_video.py "a spaceship flying through space"
python scripts/tensorslab_video.py "sunset over ocean waves" --duration 10 --ratio 16:9
python scripts/tensorslab_video.py "make this photo come alive" --source portrait.jpg
python scripts/tensorslab_video.py "abstract flowing colors" --model seedancev1profast
python scripts/tensorslab_video.py "epic mountain timelapse" --resolution 1440p --duration 10 --audio
python scripts/tensorslab_video.py "a sunset timelapse" --output-dir ./my_videos
Task Status Flow
| Status | Code | Meaning |
|---|
| Pending | 1 | Task waiting in queue |
| Processing | 2 | Currently generating |
| Completed | 3 | Done, video ready |
| Failed | 4 | Error occurred |
| Uploading | 5 | Uploading generated video |
Error Handling
Translate API errors to user-friendly messages:
Output
All videos are saved to output directory with naming pattern:
- Default:
./tensorslab_output/ (current working directory)
- Custom: Use
--output-dir or -o to specify a different path
- Naming:
{task_id}_{index}.mp4 - e.g., abcd_1234567890_0.mp4
After completion, inform user:
🎉 您的视频处理完毕！已存放于 ./tensorslab_output/{filename}
Tips for Better Results
Text-to-Video
- Include cinematic terms: "wide shot", "close-up", "pan", "dolly"
- Describe motion: "flying rapidly", "slowly drifting", "zooming in"
- Specify style: "cinematic", "documentary style", "dreamy"
Image-to-Video
- Describe the desired motion: "gentle sway", "subtle movement"
- For landscapes: "clouds moving", "water flowing", "leaves rustling"
