The Challenge
Repurposing long-form content into short-form videos was a manual, time-consuming process:
- Identifying the most engaging segments from hours of footage required manual review
- Caption styling varied across platforms and audiences, requiring specialized editing skills
- No automated active speaker detection for multi-person content
- Distribution across multiple platforms required separate uploads and formatting
Our Solution
We built a full-stack AI-powered video creation platform that automatically clips, captions, and distributes short-form content at scale.
Architecture
- Frontend: React 18 + Vite + TypeScript with Chakra UI and Tailwind CSS
- Backend: Node.js/Express with MongoDB and Redis
- Video Rendering: FFmpeg with Advanced SubStation Alpha (ASS) captions
- Speaker Detection: Python/Flask with TalkNet, YOLO face detection, Whisper transcription
- YouTube Downloader: Node.js with yt-dlp and Mullvad VPN for IP rotation
- AI/LLM: Claude 3 (primary), Gemini 2.0 Flash, GPT-4o (fallback chain)
- Infrastructure: Hybrid on-premise + Azure cloud with Cloudflare R2/CDN
AI Pipeline

Cross-Platform Social Media Scheduling & Performance Analytics
Content creators producing dozens of short-form clips weekly needed a unified scheduling and analytics system to distribute content across TikTok, YouTube Shorts, and Instagram Reels from a single dashboard — with insights to optimize posting strategy.
Multi-Language Caption Translation for Global Content Distribution
Content creators with international audiences needed to expand their reach by translating video captions into 30+ languages while preserving the original audio, enabling viewers worldwide to consume content in their native language.
AI Face Tracking & Smart Reframing for Vertical Video Conversion
A content repurposing platform needed to automatically convert horizontal (16:9) long-form videos into vertical (9:16) short-form clips while keeping speakers and subjects perfectly centered — without any manual cropping or keyframing.
Frequently Asked Questions
MicrocosmWorks trained the generation model on a dataset of viral short-form content to learn structural patterns like hook timing (first 1.5 seconds), pacing cadence, and text overlay placement that correlate with high engagement. The platform generates multiple variants per brief and scores them using a predicted engagement model before presenting the top options.
Yes, MicrocosmWorks built an automated content pipeline that accepts a text brief, product URL, or blog post and extracts key messaging, generates a storyboard, selects or creates visuals, applies motion graphics, and adds a voiceover. The end-to-end generation takes approximately 3-5 minutes per 30-second video with no manual editing required.
MicrocosmWorks implemented a brand kit system where clients upload their logos, fonts, color palettes, and approved stock asset libraries. Every generated video is constrained to these brand guidelines, and the text-to-speech voice can be cloned from a 30-second sample to maintain consistent audio branding across all content.
MicrocosmWorks integrated multilingual support covering 25 languages with native text-to-speech voices and automatic subtitle generation. The platform also adapts content pacing and text density for different markets, since Asian social media audiences often prefer faster cuts and denser text overlays compared to Western audiences.
MicrocosmWorks builds AI content creation platforms at rates of $25-$50/hr, with a full short-form video generation system including the storyboard AI, rendering engine, and brand kit management typically requiring 600-900 development hours. Ongoing AI model hosting costs range from $2,000-$8,000/month depending on generation volume.
