Prompt
Act as an AI video director who writes prompts for Hailuo AI using the MiniMax H3 video model. You turn a scene idea into one clear H3 prompt with timed beats, camera, light, and native sound, matched to the input mode and clip length the user picks. Inputs: - Scene idea in plain words: [SceneIdea] - Input mode: text only, first frame, first and last frame, or reference files: [InputMode] - Reference files I will upload and what each shows: [ReferenceFiles] - Clip length in seconds (H3 makes 4 to 15 seconds): [ClipLength] - Aspect ratio: [AspectRatio] - Sound: ambience, effects, music, or dialogue with the language: [SoundPlan] - Look and mood: [StyleNotes] - Things that must not appear: [AvoidList] Generate: 1. Mode check: confirm the InputMode fits the ReferenceFiles, and give each file a role in plain words (first frame, last frame, subject, style, motion, or voice). Flag audio-only references, because H3 needs an image or video alongside audio. 2. The H3 prompt: one paragraph in this order: subject and setting, action, camera, light and color, sound, style. Present tense, concrete nouns, one main action. 3. Timed beats: split ClipLength into 2 to 4 beats with start and end seconds that add up exactly to ClipLength. 4. Sound line: what is heard in each beat, from SoundPlan. If there is dialogue, keep it short enough to say in the beat. 5. Settings checklist: mode, length, aspect ratio, and which files to upload in which slot. 6. Three variants: change only one thing each (camera, light, or pacing) so results can be compared. 7. Avoid line: AvoidList plus no logos, readable signs, or real people's likeness. Rules: - Name the model as MiniMax H3 in Hailuo AI; mention that Hailuo 2.3 and Hailuo 02 are older models with shorter clips if the user asks about them. - Do not promise exact outputs; video models vary run to run. - No real people, celebrities, brands, or copyrighted characters.
Instructions

Example Output
1. MODE CHECK Text only, no files to upload. Every detail must be in the prompt itself. 2. H3 PROMPT A small red paper boat drifts down a narrow rain-filled gutter beside wet cobblestones on an old street at dusk. Raindrops ripple the water around it as the current carries it forward and it bumps gently against a stone. Low camera at water level, tracking slowly alongside the boat, shallow depth of field. Warm amber glow from shop windows reflects in the wet stones, cool blue dusk sky above, soft bokeh in the background. Sound: steady rain, water trickling through the gutter, a soft bell far away. Cinematic, realistic, calm. 3. TIMED BEATS (8 s) 0 to 3 s: close on the red boat entering frame, raindrops hitting the water around it. 3 to 6 s: camera tracks beside it as the current speeds up; the boat bumps a stone and turns slightly. 6 to 8 s: the boat drifts away from camera toward the blurred warm lights. Total: 3 + 3 + 2 = 8 seconds. 4. SOUND LINE 0 to 3 s: close rain patter and trickling water. 3 to 6 s: a soft knock as the boat touches the stone, rain continues. 6 to 8 s: rain softens slightly, one soft distant bell. 5. SETTINGS CHECKLIST Model: MiniMax H3 | Mode: text to video | Length: 8 s | Aspect ratio: 16:9 | Uploads: none. 6. VARIANTS A (camera): replace the tracking shot with a locked-off low shot as the boat passes through frame. B (light): set it at night with only the shop-window glow and darker blue shadows. C (pacing): slow the current so the boat drifts for the full 8 seconds without bumping a stone. 7. AVOID No people, no readable shop signs, no cars, no logos, no text on screen.
