README (SKILL.md)

JSON2Video Pinterest Skill

Generate vertical videos (1080x1920) optimized for Pinterest using the JSON2Video API.

Prerequisites

  1. JSON2Video API Key: Sign up at https://json2video.com/get-api-key/
  2. Set Environment Variable:
    export JSON2VIDEO_API_KEY="your_api_key_here"
    

Quick Start

Create a video using a JSON configuration file:

python3 scripts/generate_video.py --config my-video.json --wait

Configuration Format

The video is defined as an array of scenes. Each scene contains:

Property Type Description
image object Image configuration (AI-generated or URL)
voice object Voice configuration (generated TTS or URL)
text_overlay string Optional text displayed on scene
subtitles boolean Enable/disable subtitles
zoom_effect boolean Add Ken Burns zoom effect
duration number Override scene duration (seconds)

Image Configuration

AI-Generated Image:

{
  "image": {
    "source": "ai",
    "ai_provider": "flux-schnell",
    "ai_prompt": "A minimalist workspace with laptop..."
  }
}

Available AI Providers:

  • flux-pro - Highest quality, realistic images
  • flux-schnell - Fast generation, good quality
  • freepik-classic - Digital artwork style

URL-Based Image:

{
  "image": {
    "source": "https://example.com/image.jpg"
  }
}

Voice Configuration

AI-Generated Voice (TTS):

{
  "voice": {
    "source": "generated",
    "text": "Your voiceover text here",
    "voice_id": "en-US-EmmaMultilingualNeural",
    "model": "azure"
  }
}

Provided Audio File:

{
  "voice": {
    "source": "https://example.com/voiceover.mp3"
  }
}

Note on Scene Duration: The voiceover determines scene length automatically. Each scene's duration matches its audio length. For provided audio files, ensure they match your intended scene timing.

Complete Example

{
  "resolution": "instagram-story",
  "quality": "high",
  "cache": true,
  "scenes": [
    {
      "image": {
        "source": "ai",
        "ai_provider": "flux-schnell",
        "ai_prompt": "Affiliate marketing workspace with laptop and coffee"
      },
      "voice": {
        "source": "generated",
        "text": "Here's how to make money with affiliate marketing",
        "voice_id": "en-US-Neural2-F"
      },
      "text_overlay": "Affiliate Marketing 101",
      "subtitles": true,
      "zoom_effect": true
    }
  ]
}

Advanced: Split Long Voiceover into Scenes

For long scripts, split into multiple scenes with shorter voice segments:

{
  "scenes": [
    {
      "image": { "source": "ai", "ai_prompt": "Hook image" },
      "voice": { "source": "generated", "text": "Attention-grabbing hook..." },
      "zoom_effect": true
    },
    {
      "image": { "source": "ai", "ai_prompt": "Step 1 image" },
      "voice": { "source": "generated", "text": "Step one is to..." },
      "zoom_effect": true
    },
    {
      "image": { "source": "ai", "ai_prompt": "CTA image" },
      "voice": { "source": "generated", "text": "Click the link in bio..." },
      "zoom_effect": false
    }
  ]
}

Command Reference

Create video from config:

python3 scripts/generate_video.py --config video.json --wait

Create without waiting:

python3 scripts/generate_video.py --config video.json --no-wait

Check status of existing project:

python3 scripts/generate_video.py --project-id YOUR_PROJECT_ID

Security

  • API Key is NEVER stored in skill files
  • API key must be set as environment variable JSON2VIDEO_API_KEY
  • Script validates key exists before any API calls

Example Files

  • scripts/example-config.json - Basic example with one scene
  • scripts/example-advanced.json - Multi-scene affiliate marketing video

Advanced Usage

See ADVANCED.md for:

  • Multi-scene video architecture patterns
  • Image source strategies (AI vs URL vs hybrid)
  • Voiceover patterns and best practices
  • Subtitle styling options
  • Pinterest-specific content tips
  • Batch processing workflows
  • Credit consumption optimization

Troubleshooting

Error: "JSON2VIDEO_API_KEY environment variable not set" → Run: export JSON2VIDEO_API_KEY="your_key"

Error: "Render failed" → Check: Image URLs are publicly accessible → Check: AI prompts don't violate content policies → Check: Audio files are valid MP3/WAV

Video takes too long → Enable cache: true in config → Use flux-schnell instead of flux-pro for faster generation → Pre-generate AI images and use URLs instead

Python API Usage

For programmatic use in other scripts:

from scripts.generate_video import create_pinterest_video

scenes = [
    {
        "image": {"source": "ai", "ai_prompt": "..."},
        "voice": {"source": "generated", "text": "..."},
        "subtitles": True,
        "zoom_effect": True
    }
]

video_url = create_pinterest_video(scenes, wait=True)
print(f"Video ready: {video_url}")
Usage Guidance
Before installing, note these points: - The code and SKILL.md require a JSON2VIDEO_API_KEY, but the registry metadata does not list it — treat that as a metadata/packaging error. Do not supply high-privilege or reused credentials; use an API key scoped to rendering only, if possible. - The script sends requests to api.json2video.com (expected). If you plan to use Azure or ElevenLabs voices, verify whether you need additional keys for those services — the skill's docs mention them but the code delegates to JSON2Video (which may mediate TTS). - Source and homepage are unknown. If you need higher assurance, request provenance from the publisher or inspect the full script locally; the included Python is short and network calls are explicit (requests.post/get to JSON2Video). - For extra safety, run the script in an isolated environment or container and test with a throwaway API key. Check that logs or console output do not print your API key (the code reads the env var but does not log it). - If you rely on this skill in production, ask the publisher to correct the registry metadata to declare JSON2VIDEO_API_KEY and to document any additional credential needs. If you cannot verify the source, consider not installing or restricting the key's permissions.
Capability Analysis
Type: OpenClaw Skill Name: claw-video-generator Version: 1.0.0 The skill is designed to generate videos using the JSON2Video API. Its Python script (`scripts/generate_video.py`) securely retrieves the API key from environment variables and interacts solely with the specified `api.json2video.com` endpoint. While the script fetches images and audio from user-provided URLs, this is a core functional requirement for video generation and not indicative of malicious intent. The `SKILL.md` and `ADVANCED.md` documentation provides clear, benign instructions without any prompt injection attempts or instructions for unauthorized actions. All observed behaviors are clearly aligned with the stated purpose and lack high-risk activities like data exfiltration, persistence, or unauthorized remote execution.
Capability Assessment
Purpose & Capability
Name/description claim to generate Pinterest vertical videos via the JSON2Video API; the included Python script and SKILL.md both build JSON payloads and call https://api.json2video.com/v2 with an API key — this is coherent. However, the registry metadata lists no required environment variables while the instructions and code require JSON2VIDEO_API_KEY, which is an inconsistency.
Instruction Scope
SKILL.md instructs only to set JSON2VIDEO_API_KEY, run the included script with a JSON config, and use example files. The runtime instructions and code operate on provided config files and the JSON2Video API only; they do not instruct reading unrelated system files or sending data to unexpected endpoints.
Install Mechanism
This is an instruction-only skill with a small accompanying Python script; there is no install spec and no downloads from third-party URLs. Risk from install mechanism is low.
Credentials
SKILL.md and scripts require the JSON2VIDEO_API_KEY environment variable, but the registry metadata declares no required env vars or primary credential — this mismatch is concerning and could cause users to miss that a secret is needed. The skill references third-party providers (Azure voices, ElevenLabs, Cloudinary, etc.) in docs, but those are optional integrations and the code only requires the JSON2Video API key.
Persistence & Privilege
The skill does not request persistent/always-on privileges (always=false), does not modify other skills, and does not write system-wide configs. Autonomous invocation is allowed (default) but not combined with other high-risk requests.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)

  3. After installation, invoke the skill by name or use /claw-video-generator
  4. Provide required inputs per the skill's parameter spec and get structured output
