Make value prop video ads from HTML with Claude or Codex

Teach your coding agent to build fast, cheap value prop video ads from a brand's logo and product images, using HTML instead of a video model.

GooseworksOctober 3, 2026 · 1 min read

A value prop video ad explains your product's benefits in a fast-paced, vertical video. Brands have used the format for years. You can now have Claude or Codex make one for you from HTML, with no video generation model.

HTML videos are quick to produce and cheap to run. Because the agent writes the video as code, making five variants costs about the same effort as making one.

What you need

Claude Code or Codex
The Gooseworks skills
A brand with a logo and some product images

Make one in three commands

Install the skills:

npx gooseworks install --all

npx gooseworks login

Ask for the ad:

/goose-video make a value prop ad for my brand

The skill researches your brand, scrapes the logo and product images, downloads the video recipe and builds the video from start to finish.

Pick the benefit

The recipe uses the benefit angle. If you want to market specific benefits, put them in the prompt:

/goose-video make a value prop ad for my brand that focuses on fast setup and no monthly contract

Edit by asking

To change anything, say so in the next prompt. Shorter copy, a different order of benefits, a new end card. The skill handles the edit and re-renders.

Check before you run it

Product photos are real product shots. Brand research sometimes saves a mascot or illustration as a product photo, and then the video features the mascot.
The logo is the correct version, placed as-is.
Each benefit stays on screen long enough to read.

HTML is also how we make iMessage video ads. Both are formats the /goose-video skill supports.

Skills used in this post

Render Value Prop

Render a designed 'value prop' video from a config — 3-5 noun-phrase benefit claims (<=4 words each) revealed sequentially over per-SKU product visuals, one crisp editorial frame per claim (hook sticker -> N claim beats -> brand end card). Deterministic PIL/HTML beat renderer frame-stepped via Playwright and encoded with FFmpeg, sound-off legible, hard cuts, uniform pacing. FREE (no paid calls); music is added separately (create-music-elevenlabs). Use for the value-prop format.

Video Production Harness

Full video production sequence with script review, actual ingredient choices, controlled generation, editing, evidence-based quality review, polish, captions and delivery. A host binding supplies project storage, authentic approvals, provider access and billing.

Write Video Ad Script

Write the words of a short-form video ad (voiceover, dialogue, chat bubbles, on-screen lines) the way performance creative teams do instead of from a blank page. Builds the script from the buyers' own words, the beat sheet of an ad that already works and three deliberately different angles, filters them with a rule check and a second non-Claude model, and takes the strongest into the review with the other two as one-line swaps. Use it in every video ad run before any paid step, and whenever the user asks to write, rewrite or improve a video ad script or says a script sounds generic or AI-written.
