AI Video Automation – PoC
An end-to-end AI system converting text briefs into completed marketing videos featuring voiceover, text overlays, background music, and B-roll — with zero manual editing. Built for a digital marketing agency managing video campaigns for 30+ clients to validate replacing manual production with automated processing. The workflow accepts campaign briefs, generates scripts via LLM, creates voiceovers, sources stock footage through semantic search, composites elements via FFmpeg, and delivers MP4 files in under 10 minutes.
The problem we solved
Marketing teams required scalable video content but lacked production capacity. The agency produced 40–60 videos monthly, with each consuming 6–8 hours of editor time. Growing client demand made manual scaling economically unfeasible.
What we built
A composition pipeline that turns briefs into finished videos: LLM-powered scripts, AI voice synthesis, semantic stock-footage search, and automated FFmpeg assembly with captions, lower-thirds, and music mixing.
The impact
The PoC produced 12 campaign videos during the pilot, reducing per-video cost by 80% and production time from 7 hours to 8 minutes. Creative evaluation rated outputs acceptable for tier-2 social content, and the board approved full product development.
