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 still image, with 6 copy slots you fill.
When to use it
For static placements where a native look outperforms a designed one, and as the still counterpart to the iMessage and Notes video templates so a campaign can run both.
The thing to get right
The iMessage variant defaults to a full-bleed screenshot crop cut before the keyboard, which is how these ads are actually cropped in the wild. The whole-phone-on-a-gradient version is an option rather than the default.
The format at a glance
- Output — a still image.
- 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 — static-mockup.
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.
Which sub-style should I pick?
The frozen iMessage thread for a recommendation, the Apple Notes card for a piece of writing, the brand promo card for an offer. It is also the still counterpart to the iMessage and Notes video templates, so one campaign can run the same idea in both placements without redrawing it.
