Architecture

​
6-Stage Pipeline

1

Download & Validate

Fetch video from URL, validate format, extract metadata. Supports YouTube, direct URLs, and uploaded files.
2

Transcribe

AssemblyAI processes audio with word-level timestamps and speaker diarization. Produces timestamped transcript with speaker labels.
3

Analyze

Claude performs a 3-pass analysis:
  • Pass 1: Topic segmentation — identify distinct content blocks
  • Pass 2: Hook identification — find viral-worthy moments
  • Pass 3: Scoring — rank segments by engagement potential
4

Face Track

MediaPipe detects and tracks speaker faces. Smart 9:16 cropping centers on the active speaker for vertical video format.
5

Render

Remotion + FFmpeg render final clips with:
  • Animated TikTok-style captions (word-by-word highlight)
  • Brand color overlay
  • Speaker-centered framing
  • Platform-optimized encoding
6

Generate Text Content

Claude generates platform-specific written content:
  • LinkedIn posts with pull quotes from transcript
  • Twitter threads with key insights
  • SEO-optimized blog post (2,000+ words)
  • 7-day content calendar with scheduling
After pipeline completion, content enters an approval queue before publishing to 6 platforms: YouTube Shorts, TikTok, Instagram, LinkedIn, X/Twitter, and Telegram.
