video-content-analyzer（视频内容分析器）

Video Content Analyzer

Analyze short-form videos with Gemini AI to extract hooks, content structure, delivery style, and CTA strategies.

Prerequisites

• GEMINI_API_KEY environment variable
• google-genai and requests Python packages

Usage

python3 .claude/skills/video-content-analyzer/scripts/analyze_videos.py \
  --input outliers.json \
  --output video-analysis.json \
  --platform instagram \
  --max-videos 5

Parameters

Input Format

Accepts outlier JSON from platform-specific research skills. Handles both formats:

• Direct list: [{post1}, {post2},...]
• Wrapped: {"outliers": [{post1}, {post2},...]}

The script automatically maps platform-specific fields:

TikTok Note: The Apify TikTok Scraper returns webVideoUrl (the TikTok page URL) rather than a direct video download URL. Gemini will attempt to analyze from this page URL.

Output

Returns JSON array with analysis for each video:
