A real example
What "A woman notices something is wrong in a greenhouse, then speaks" becomes in MiniMax H3's grammar.
Anamorphic 35mm optics, muted greens against a single warm source, low-key side light, fine film grain. <Subject 1> is Maya, with the exact face, freckles and white lab coat from <Picture 1>. <Subject 2> is the greenhouse itself, its glass panes and hanging ferns from <Picture 2>. Maya stands at the potting bench in the greenhouse, one hand resting on an overturned seed tray. Static Shot, the camera holds still, framing fixed. [Shot 2] At 00:03.000, the camera cuts to a close-up of her face as she lifts her eyes toward the cracked pane. The young woman with a low, weary voice (S1) says: <d>[English] Someone's been in here.</d>
Why MiniMax H3 needs its own grammar
Every engine has a genuinely different prompt structure — reusing one engine's format on another degrades output, it doesn't just look different.
- Reference binding, multishot syntax and dialogue markup are all specific to MiniMax H3 — copying a prompt written for a different engine will not transfer cleanly.
- The grammar this tool follows is the exact same reference the Scenes AI pipeline itself uses when writing prompts for this engine.
- A malformed prompt for a given engine usually doesn't error — it just produces a worse clip, silently.
