PromptEN260 characters
Molten iron pours in a giant's forge while a row of bare-backed smiths shield their faces; the pour is the only light source and it throws every body into orange relief, sparks landing and dying on wet skin. Cinematic, heavy film grain, molten orange in black.Written in English, exactly as we sent it.

Why this prompt works
One light source, and it is moving. The brief makes a pour of molten metal the only illumination in frame, so exposure changes across the shot and every body in it is lit by the same travelling source — a much harder problem than a static key. Written from nothing at `1080p`, `16:9`, `duration_seconds` `5`, with `generate_audio` left on so the forge noise is rendered against the picture.
Settings used
| Setting | Value | What it does |
|---|---|---|
| resolution | 1080p | Output resolution, 720p by default and reaching 4k; no upscaled tier is offered on this endpoint. It sets a rate tier, and higher tiers mean bigger files and longer renders. Draft at 480p and raise it only as far as the delivery needs. |
| aspect_ratio | 16:9 | Output framing, `adaptive` by default: the model picks the shape the prompt describes — ask for a vertical short-form shot and it usually composes vertically. Six fixed ratios are there for when the placement format is already decided. No effect on billing. |
| generate_audio | true | Whether a native soundtrack is rendered in sync with the picture. On by default; switch it off when you need picture-only material to score or dub later. |
| duration_seconds | 5 | Length in whole seconds, 4 to 15, defaulting to 5, and the billed quantity. Pass -1 and the model picks the length itself: the estimate assumes the 15-second maximum and the final charge follows the delivered length. The extra seconds over the previous generation are room to finish an action, not licence to cram in a second idea; longer pieces are cut together from several takes. |
