E-commerce Video Skills

Turn one product photo into a narrated vertical video with subtitles

Problem

E-commerce sellers can get AI to write a product video script, but then they still have to manually drag clips in CapCut or similar editors. Generic AI video tools struggle to keep the product image and copy under control.

Solution

An open-source set of Agent Skills that lets an LLM output a storyboard.json (which image, motion, voiceover, highlighted subtitle word per shot), then renders a 15-second vertical video with voiceover and subtitles via a local ffmpeg command.

Users

E-commerce sellers, short-video creators, indie store operators

MVP

Define storyboard.json format; provide prompts for LLM to generate shots; local ffmpeg render script; support voiceover and subtitles; output vertical MP4

Revenue

Open-source core with paid template packs and hosted rendering; or a SaaS charging per render.

Why now

LLM scriptwriting is mature, ffmpeg rendering is dirt cheap locally, and e-commerce short video demand is exploding. A solo developer can ship open-source skills and monetize hosting.
