It is one of 13 native HTML ad templates in Hermoso — formats rendered from real markup by a browser rather than generated by a model. This one outputs a set of carousel slides, with 6 copy slots you fill.
When to use it
Educational and listicle content, and any ad that needs several distinct points. Unlike every other template it returns a set of images rather than one asset.
The thing to get right
The arc is locked deliberately: cover, then one key point per slide with a hard density cap, then the close. A content slide can instead be a statistic, and the progress ring only fills when the number is genuinely a percentage.
The format at a glance
- Output — a set of carousel slides.
- Copy slots — 6, each with its own character budget derived from the layout rather than guessed.
- Assets required — none — it renders from copy and your brand alone.
- Template id — carousel.
How this template renders
Nothing here is generated by an image or video model. The format is a self-contained HTML page whose animation is a pure function of time — no CSS keyframes, no timers, no randomness — and the renderer steps that page frame by frame in headless Chrome, screenshots each frame, and assembles them with ffmpeg into an H.264 file that ends on a crossfade into your brand end card.
Two things follow from that. The render is deterministic: the same inputs produce the same file, so a format that looked right yesterday looks right today. And every word on screen is real browser-rendered text, which means the copy is exact and stays sharp at any resolution. The whole thing costs a couple of credits rather than a video generation, which is what makes these formats practical to run at volume.

Driving it from an agent
Every format on this site is reachable from an AI agent as well as the web studio. Hermoso ships an MCP server, so Claude, Claude Code, Cursor, Codex and any other MCP client can call plan_ad to draft the creative and render_ad to produce it, name a format as the recipe, and get a finished file back — with the same brand grounding and the same composited-text guarantees. The MCP and CLI overview covers the setup, and the generated tool reference is the complete list.
