How I Built a Pipeline That Turns Any Website URL Into a Narrated 16:9, 9:16 & 4:5 Launch Video in 10 Minutes

Every founder knows the feeling: you spend months building a real product, shipping the backend, and polishing the landing page—and then launch day arrives and you realize you don't have a 60-second launch video for Product Hunt, LinkedIn, or X.

Hiring a studio takes 2–4 weeks and $2,000+. Opening CapCut or After Effects eats an entire weekend.

After maintaining openapi-mcp-generator (589,000+ npm downloads), I kept seeing solo builders and small teams launch quietly because video production was the bottleneck. So I built CrossLoop.

What CrossLoop does from a single URL

You paste any public product URL into crossloop.ai, and in about 10 minutes the pipeline:

1. Reads your live DOM & brand tokens: Extracts your headline hierarchy, proof points, UI visuals, and brand color palette.
2. Writes a structured 60-second launch script: Follows a proven 5-part arc (0–5s Hook, 5–20s Product in action, 20–45s Three proof points, 45–52s Social proof, 52–60s CTA).
3. Synthesizes voiceover + word-by-word .srt timing: Records a clean narration and aligns frame transitions to word timestamps.
4. Renders all 3 social formats simultaneously:
   • 16:9 (1920×1080) for YouTube, homepage hero, and Product Hunt gallery
   • 4:5 (1080×1350) for LinkedIn and Instagram feed posts
   • 9:16 (1080×1920) for Reels, TikTok, and YouTube Shorts
5. Generates platform-native post copy: Ready-to-post LinkedIn and Instagram captions tailored to your product.

Why we skipped subscriptions ($9 per film)

Founders don't want another $49/month recurring SaaS bill just to ship a launch video. CrossLoop is flat per-film pricing starting at $9 (or $19 for a Studio film, with a 7-day 100% money-back guarantee).
