Turn long videos into finished AI avatar shorts automatically

Takes a video transcript, writes short-form scripts with AI, generates avatar narration and B-roll, and renders finished vertical shorts.

How the work actually flows

A straight line. Runs once per each generated script.

The problem it solves

Turning one long video into several polished short-form clips means writing new scripts, filming or finding an avatar presenter, sourcing B-roll, and editing everything together, which can take a full production team days to finish.

Who it fits

Content creators and marketing teams who want to repurpose long-form video into short-form content at scale.

How it works

  1. Video transcript and key moments are received from another workflow
  2. AI writes three short-form scripts with hooks and calls to action
  3. An AI avatar records the narration for each script
  4. AI generates supporting video clips to match the script
  5. Finished vertical videos are assembled and saved to Google Drive
What you get

Short videos produced from your long-form content

You get short vertical videos with AI avatar narration produced automatically from your long-form video content, ready to post.

What you get

Finished, rendered vertical short videos with avatar narration, saved to Google Drive and logged in a sheet.

What you need

Accounts with HeyGen, Replicate, and Creatomate, a Gemini API key, an OpenAI API key, and Google Drive and Sheets access.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
