Turn a TOPIC into a finished narrated explainer video. Writes a sectioned script, paints a BURST of pictures per section (about one every 1.5s — most of them one-detail edits of the frame before, so it reads as movement rather than a slideshow), narrates each section with TTS, holds each picture PERFECTLY STILL for its own slice of the narration (the motion is the CUT RATE, exactly as Higgsfield's stills pipeline does it — a slow move on a still shimmers), then composites the end card (and any on-screen text you asked for) with the Chrome+ffmpeg engine the ads use (text is never model-painted, so it never garbles). BURNED ON-SCREEN TEXT IS OFF BY DEFAULT — the narration carries the point and the pictures carry the story, so the film ships clean unless the user asks otherwise; `captions:true` adds held key points and `subtitles:true` adds narration-timed CAPS (see both). It is an image film WITH motion, not N video-model renders — that's what keeps it affordable. `style` picks the visual family: the default 'cinematic' is photoreal editorial; every other id is a STYLED, strictly non-photoreal look (illustrated / collage / clay / pixel …) that first renders ONE style-key image and then locks every scene to it, so the whole film holds one look. Cost at the default frame density: a ~130-credit hold for a 60s explainer on the default style, ~100 styled; `frameDensity:'lean'` roughly halves it and `'minimal'` (one picture per section) is ~30. All settle to the exact per-frame image + narration spend (a longer target = more sections = more). Takes SEVERAL minutes — one image render per frame; independent frames are painted concurrently, so it is far faster than the frame count suggests. Needs the writing model and a narration voice engine connected. NOT the tool for a short product ad — use render_ad or generate_video for those, and make_template_ad for the deterministic native formats.
