Render ad video
render_adRender a finished video ad from a plan_ad storyboard with studio-quality speech, composited text, brand end card, licensed music, and optional saved creator.
Instructions
RECOMMENDED for finished video ADS: render a plan_ad concept through the SAME quality pipeline as the Hermoso web Studio — timed shot list, exact/clean speech (no garbled words), text composited in post (never model-painted), brand end card, licensed music bed, real product references. Pass plan_ad’s full structured output as creative. Honors the plan’s render_plan structure/duration: a storyboard that FITS ONE CLIP OF THE RENDER MODEL renders as a single continuous pass; anything longer automatically renders as STITCHED ACTS (the fewest balanced clips, each at most one model clip) — never time-compressed into one clip. That threshold is the render model’s own maximum, not a fixed number: most models cap a clip at 15s and the longest-clip one goes to 30s, so use dryRun:true to see the act split this plan will actually get, for free, before spending. CAST A SAVED CREATOR with creator so the SAME person stars in this ad as in the last one (list_creators is the roster) — otherwise every render invents a new face. Renders take 1–3 min; keep polling get_job if it returns still-rendering. Spends credits.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| model | No | video model id from hermoso_capabilities (default: the plan’s pick). Naming one is a DELIBERATE pick — the server asks before ever swapping it (no silent fallback) | |
| music | No | licensed music bed on/off (default on) | |
| dryRun | No | return the routing decision (single pass vs stitched acts, resolved model + act lengths) WITHOUT submitting a render — free, nothing charged | |
| lockup | No | persistent brand-logo lockup overlay on/off | |
| creator | No | CAST A SAVED CREATOR in this ad — their id from list_creators, or the name you know them by (“Sarah”). Their saved portrait becomes the on-camera identity for the whole spot, so the same face carries across every act and across every ad you render for this brand — and because we already have their picture, the character portrait this pipeline would otherwise generate is skipped, so casting somebody costs LESS than not casting them. Omit to let the ad cast a fresh person. Refused for free, with nothing rendered, if the name matches nobody or more than one creator, if the plan has nobody on camera, or if they are a REAL person with no likeness consent on file. | |
| endCard | No | branded end card on/off (default: on, except organic recipes) | |
| captions | No | burn the plan's per-scene on-screen words as caption pills. DEFAULT FALSE — leave it off unless the user asks for on-screen text (no captions, or true subtitles of what is said; never scene or emphasis labels); a recipe whose format IS on-screen text keeps its text either way | |
| creative | Yes | the FULL structured output of plan_ad (must contain video_storyboard) | |
| ttsVoice | No | voiceover voice name (e.g. Rachel / George) when the plan voices over | |
| resolution | No | '1080p' default (what we ship and bill for); '480p'/'720p' = cheaper draft passes, '4k' = premium final delivery (more credits). NOT EVERY MODEL OFFERS EVERY TIER — this enum is what the tool accepts, and each model's OWN `resolutions` list in hermoso_capabilities is what it can actually render (the longest-clip 30s model, for one, tops out at 720p). Ask for a tier the chosen model does not list and it is rendered at that model's best available tier instead, with nothing in the reply saying so — so check `resolutions` before promising anyone 1080p or 4k. | |
| aspectRatio | No | output aspect ratio, e.g. 9:16 (default) / 1:1 / 16:9 | |
| durationSeconds | No | total ad length in seconds (supported range 4–180; outside that it is clamped). Omit to honor the plan’s own duration — that is almost always right. This only RE-TIMES an already-authored board (its scenes are scaled to fit), it does NOT re-write it, so to change the length of the ad the user asked for, re-run plan_ad with durationSeconds instead. A length that fits ONE clip of the render model renders as one continuous pass; longer is stitched from acts filled to that model’s clip maximum with the remainder last — the maximum is 15s on most models and 30s on the longest-clip one, so use dryRun:true to see the exact act split for free before spending. | |
| allowGenericProduct | No | proceed even though this brand has NO product photo on file and the ad features a product — the packaging will be INVENTED. Only pass true after telling the user that and hearing they are fine with a generic stand-in |
