Chrvoje Engineering

The AI pipeline we built for an engineering channel: the client types one idea, approves three steps, and a finished video is published.

The problem

Deep technical knowledge — semiconductor device physics one week, cellular biology the next — and no repeatable way to publish it. Every video was a one-off. The subjects are genuinely three-dimensional and were being explained with static diagrams, and nothing connected the audience on short form to the substance on long form.

What we did

  1. 01Designed a production system rather than a series: templates, a shot grammar, and a schedule the channel could actually sustain.
  2. 02Built 3D that shows the thing working from the inside — the doped layers of a transistor, airflow separating off a wing, a nanobot meeting a cell — which is the part a cutaway drawing cannot do.
  3. 03Ran long form and short form off one pipeline, so a short is a by-product of the main edit rather than a second job.
  4. 04Built a custom AI-powered pipeline on top of that system. The client types a video idea; the system, which holds the channel's full context, drafts the script for approval, plans every shot before anything is generated so nothing is wasted, then produces the shots and the voice — any of which can be changed.
  5. 05Closed the loop at the other end: a custom thumbnail the client approves, automatic upload, and the blog post and article published alongside the video.
  6. 06Shipped an interactive, tool-based web app so the audience can change the inputs and watch the behaviour change, with a wider set of applications and interactive pages built to follow it.

How the pipeline runs

  1. Hrvoje, founder of Chrvoje EngineeringHrvojeThe idea

    “Why does airflow separate off a wing?”

    One line from the client. That is all it needs.

  2. 01

    Script

    Written in the channel's own voice, from everything it has published.

    You approve
  3. 02

    Shot plan

    The whole video planned before any of it is made.

    You approve
  4. 03

    Generate

    Shots and voice are produced. Any of them can be changed.

    Publish

    Uploaded automatically, with the post and article.

Where it landed

Past two million organic views across formats with no paid promotion, and a publishing system — now an AI-powered one — that no longer depends on any single video going well.

AI content pipeline

“I had the engineering knowledge and no system for getting it out. Ayuvam built one. I type a video idea, it writes the script in my channel's voice for me to approve, shows me every shot before anything is generated, and publishes when I say so. I still make every decision; I just don't do the repeat work. Past two million organic views, none of it paid.”
