MiniMax-H3 — image-to-video prompt format

Twelve entries from the image_to_video prompt library, each run as written and rewritten to MiniMax's I2VA format (integrated_multimodal_description / overall_soundscape / non_diegetic_music, with the <Picture 1> reference line). Everything else identical: 124 frames (5.17 s), 50 steps, seed 777, SageAttention 2 + First Block Cache 0.10, RTX 5090 — generated by the image-server port with comfy-kitchen absent. Source frames are Flux.2-Klein-4B. Mean sampling 111s. 5 of 12 raw clips came out essentially silent (rms < 0.01) against 2 of 12 rewritten.

The rewrite is compute-free — measured, not assumed. All 24 clips ran 110.4–112.1s at 2.21–2.24s/it with 34/50 steps skipped; the ~1% spread is the longer text encode. It costs encoder tokens, not sampling time.

Judge by watching and listening. ⚠️ Do not read the rms figures as a quality score — several rewrites deliberately ask for near-silence ("almost silent", "near silence"), so a low value there is the requested outcome, not a defect. What the numbers do show is clips with no usable audio track at all: the raw prompts specify no audio whatsoever and H3 synthesises a track regardless, so it fills the gap with whatever it infers. The starkest pair is the steaming mug — raw 0.0014 (silent) against rewritten 0.2018.

The last four pairs test something separate — whether monochrome, sepia, impressionist brushwork and flat art-deco graphics survive being animated, since a video model's prior pulls hard toward photoreal. The rewrites restate the medium inside the motion sentences rather than only at the top; the raw ones name it once.

For the target video, at 0.00 seconds into the target video, <Picture 1> (from [Shot 1]) is fully referenced. integrated_multimodal_description: [Shot 1] Live-action, cinematic, a close-up portrait holds the woman exactly as shown in <Picture 1>, preserving her dark hair pulled back, the soft directional window light on the left of her face, the neutral dark top, and the muted grey interior behind her. She begins perfectly still, then her chest rises and falls in a slow steady breath, her shoulders settling a fraction on each exhale. Her eyes stay level on the lens and hold a quiet intensity, blinking once, unhurried. A few loose strands near her temple drift very slightly. The camera holds completely static throughout, and the shallow depth of field keeps the background soft. overall_soundscape: A quiet interior room tone, faint and close, with the barely audible sound of slow breathing. non_diegetic_music: A sustained low string drone, very soft, with no discernible rhythm.

For the target video, at 0.00 seconds into the target video, <Picture 1> (from [Shot 1]) is fully referenced. integrated_multimodal_description: [Shot 1] Live-action, cinematic, a medium close-up holds the elderly woman exactly as shown in <Picture 1>, preserving her deeply lined face, her position beside the window, the warm afternoon light falling across one cheek, and the muted interior behind her. She breathes gently, her shoulders lifting and settling, then her eyes track slowly to the left as she follows something beyond the frame, pausing there before drifting back. The afternoon light shifts softly across her face as cloud passes outside, warming and then cooling by a small degree. The camera pushes in with very small amplitude at slow speed. overall_soundscape: Soft room tone, a distant bird outside the glass, and the faint hush of wind against the window frame. non_diegetic_music: A slow, sparse piano figure in a high register, leaving long gaps between notes.

For the target video, at 0.00 seconds into the target video, <Picture 1> (from [Shot 1]) is fully referenced. integrated_multimodal_description: [Shot 1] Live-action, cinematic, a close-up portrait holds the young man exactly as shown in <Picture 1>, preserving his calm neutral expression, the warm indoor light on his face, and the softly blurred interior behind him. He begins composed and still, then the corners of his mouth lift by a small degree into a subtle smile that continues to grow, and his eyes warm and narrow slightly as the expression reaches them. The change is very slow and deliberate across the whole clip, never becoming a broad grin. The camera holds static, and his head turns only a fraction toward the light. overall_soundscape: A close quiet interior, faint clothing movement, one soft breath. non_diegetic_music: A warm sustained pad, gentle and unresolved, rising almost imperceptibly.

For the target video, at 0.00 seconds into the target video, <Picture 1> (from [Shot 1]) is fully referenced. integrated_multimodal_description: [Shot 1] Live-action, premium product cinematography, the frame holds the luxury mechanical wristwatch exactly as shown in <Picture 1>, preserving its metal case, the dial detail, the polished dark surface beneath it and the deep black background. The watch rotates slowly and continuously on its axis throughout the clip, and as it turns the rim light travels across the dial, picking out the indices in sequence and drawing a moving highlight along the case edge. A sharp specular glint crosses the sapphire crystal once as the angle passes the light. The camera does not move at all and the framing is locked. overall_soundscape: A near-silent studio space with a very faint, precise mechanical ticking. non_diegetic_music: A minimal electronic pulse, low and controlled, with a slow steady tempo.

For the target video, at 0.00 seconds into the target video, <Picture 1> (from [Shot 1]) is fully referenced. integrated_multimodal_description: [Shot 1] Live-action, elegant product cinematography, the frame holds the faceted glass perfume bottle exactly as shown in <Picture 1>, preserving its shape, the amber liquid inside, the white marble surface and the soft shadows around its base. The bottle itself remains completely still. Sunlight refracts through the liquid and the cut glass, and the resulting prismatic colour drifts slowly across the marble beside it, stretching and narrowing as the light angle changes. The highlights on the bottle's facets brighten and fade in turn. The camera pushes in with very small amplitude at slow speed. overall_soundscape: A still, quiet interior with a faint sense of open air, almost silent. non_diegetic_music: A soft ambient shimmer with a slow, unhurried swell.

For the target video, at 0.00 seconds into the target video, <Picture 1> (from [Shot 1]) is fully referenced. integrated_multimodal_description: [Shot 1] Live-action, warm lifestyle cinematography, the frame holds the ceramic mug of coffee exactly as shown in <Picture 1>, preserving the mug's glaze, the wooden table, and the softly blurred kitchen behind it. Fine steam rises continuously from the surface of the coffee, curling and thinning as it climbs and catching the light as it passes through the beam. The morning light from the left warms gradually across the clip, deepening the highlight along the mug's rim and lengthening the shadow it casts on the wood. The camera holds static. overall_soundscape: A quiet kitchen: faint room tone, the distant tick of a clock, no voices. non_diegetic_music: A slow acoustic guitar figure, warm and simple, with a gentle tempo.

For the target video, at 0.00 seconds into the target video, <Picture 1> (from [Shot 1]) is fully referenced. integrated_multimodal_description: [Shot 1] Live-action, epic landscape cinematography, a wide shot holds the mountain ridge exactly as shown in <Picture 1>, preserving the layered peaks, the shadowed valley below, the banded cloud across the ridge line and the deep blue upper sky. The clouds shift slowly and continuously from left to right across the ridge, thinning as they pass the summit. Dawn light advances down the far slope and creeps across the valley floor, lifting it out of shadow by degrees. In the upper frame the remaining stars fade as the sky brightens toward the horizon. The camera pushes in with very small amplitude at slow speed. overall_soundscape: High-altitude wind moving in long gusts, otherwise vast and empty. non_diegetic_music: A wide sustained orchestral drone, slow and gradually swelling.

For the target video, at 0.00 seconds into the target video, <Picture 1> (from [Shot 1]) is fully referenced. integrated_multimodal_description: [Shot 1] Live-action, cinematic night photography, the frame holds the rain-slicked street exactly as shown in <Picture 1>, preserving the neon signage, the wet asphalt, the coloured reflections stretched across the puddles and the lone figure in a long coat far down the street. Light rain continues to fall, and each drop disturbs the puddles so the neon reflections ripple and re-form continuously. The distant figure walks slowly away, and the hem of their coat lifts and settles in a light breeze. Reflected reds and blues slide across the wet surface as the signage flickers. The camera pushes in with small amplitude at slow speed. overall_soundscape: Steady light rain on asphalt, distant traffic, the faint electrical hum of neon. non_diegetic_music: A slow melancholic piano line over a low synthesizer bed.

For the target video, at 0.00 seconds into the target video, <Picture 1> (from [Shot 1]) is fully referenced. integrated_multimodal_description: [Shot 1] Live-action in the style of a 1940s black-and-white studio photograph, and the image remains fully monochrome with visible film grain throughout, never gaining colour. A medium shot holds the couple exactly as shown in <Picture 1>, preserving their formal period clothing, their close posed positions, the soft studio lighting and the plain backdrop. Both breathe gently and almost imperceptibly, their shoulders settling. The woman's eyes lower briefly, hold, then return to the lens. The man's expression stays formal and still. All motion is very slow. The film grain continues to shimmer across the frame and the camera holds completely static. overall_soundscape: The soft hiss and faint crackle of an old optical soundtrack, no room noise. non_diegetic_music: A distant, slightly warped 1940s orchestral ballad, as if from a wind-up gramophone.

For the target video, at 0.00 seconds into the target video, <Picture 1> (from [Shot 1]) is fully referenced. integrated_multimodal_description: [Shot 1] Live-action in the style of an aged Victorian photographic portrait, and the sepia toning, paper texture and vignetting are maintained across the entire clip, never becoming full colour. A medium shot holds the family exactly as shown in <Picture 1>, preserving the seated bearded father, the small child on his lap, the mother standing beside them, their formal nineteenth century clothing and the stiff studio pose. The father's chest rises slowly and lowers. The child's hand adjusts a small degree in their lap and settles. The mother remains almost entirely still, blinking once. The camera holds completely static and the aged paper grain persists throughout. overall_soundscape: A very quiet interior with faint clothing rustle, otherwise near silence. non_diegetic_music: A slow solo piano in a minor key, sparse and softly recorded.

For the target video, at 0.00 seconds into the target video, <Picture 1> (from [Shot 1]) is fully referenced. integrated_multimodal_description: [Shot 1] An animated impressionist oil painting, and the thick visible brushstrokes and canvas texture are preserved throughout, so the image never resolves into photographic detail. The frame holds the meadow exactly as shown in <Picture 1>, preserving the tall grass, the wide bright sky and the loose painterly technique. The grass sways continuously in a soft wind, and the individual brushstrokes that form it shift and re-lay themselves as it moves. The sky lightens gradually across the clip, its strokes warming toward the horizon. The paint surface keeps its impasto relief and the camera pushes in with very small amplitude at slow speed. overall_soundscape: A soft meadow wind through grass, with distant birdsong. non_diegetic_music: A light, airy string figure with a gentle rocking rhythm.

The frame holds the woman exactly as shown in <Picture 1>, preserving her 1920s styling, the geometric sunburst behind her and the poster-like composition. She breathes slowly, her shoulders lifting and settling as flat shapes rather than as modelled form. Her eyes shift slightly to the side and return. The geometric rays behind her hold their positions. The camera holds completely static. overall_soundscape: A quiet interior with a faint vintage room tone. non_diegetic_music: A muted 1920s jazz piano, distant and softly recorded.
