One of our clients needed 70 ad video variants in a week, so we built an AI agent to do it in seven hours.

The build itself was a project. It required: - Assembling a Claude agent connected to Remotion - Building a knowledge base of the client's brand: brand guide, movement language, hook creation guidelines, past deliverables, briefing structure - Teaching the agent to read the brief the way our team would - Composing hook variants adapted for each aspect ratio (1x1, 9x16, 16x9) - Assembling endcards and outputting files named and organized for QA

The first batch still needed heavy manual editing. The second, the agent assembled alone.

The third came out fully stitched (hook, body, CTA, disclaimer) needing only a review pass before shipping.

Each iteration meant testing what the agent got wrong, adjusting the skills, refining the knowledge base, and rerunning until the output matched the standard our team would ship.

When we sent the batch, the client feedback was: "The revised videos look great. We'll start using them immediately."

To show what this workflow can do, the video in this post was produced by this exact system.

70 ad variants in seven hours is wild. remotion?

Heron AI is an agent that reviews architectural models and flags building code problems. The hardest part of the brief was making that legible in the first few seconds.

We built the hero as a small interaction instead of a statement. The visitor drags across a black and white building sketch and violations surface where they drag, annotated with real IBC clauses. It puts the person in the agent's position for a moment.

Everything after that section can then talk in normal product language, because the core idea has already landed without needing to be described.
