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 video, with 4 copy slots you fill, and it needs 4 product photos from your brand before it will run.
When to use it
For collections, ranges, before-and-after sets, and any brand with a library of good photography that has nowhere to go. It turns a folder of images into a designed video.
The thing to get right
It needs four photos. The format is the assembly of a grid, so the tiles have to be genuinely different pictures rather than crops of one.
The format at a glance
- Output — a video.
- Copy slots — 4, each with its own character budget derived from the layout rather than guessed.
- Assets required — 4 product photos.
- Template id — photo-grid.
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.
Can I use crops of the same photograph?
No. The format is the assembly of a grid, so it needs four genuinely different pictures. Crops of one image assemble into a grid with nothing to reveal, which is the one thing the animation exists to do.
