MiniMax H3で架空のエクササイズアプリのCMを生成。

MiniMax H3は素晴らしいのですが、実写の人間の早い動きに関してはSeedance 2.5の方が上のような...🤔

引用元の動画（Seedance 2.5で作った動画）の動きと比較すると、やはりSeedance 2.5の方が本物っぽいと感じます。
スポーツ系の広告動画などを作る場合はSeedance 2.5を選択した方が良いのかなと思います😃

とはいえ、もちろんSeedance 2.5もMiniMax H3も、どちらも素晴らしい動画生成モデル。

1ヶ月前までSeedance 2.0一色だったことを考えると、本当にすごい変化です。
私は22年くらいIT・ネット業界にいますが、AI分野の変化の速さは桁違いですね😳

integrated_multimodal_description:

Live-action, cinematic, photorealistic, a night-city running commercial in 16:9 with exactly 10 distinct cuts at 24fps. This film is 60% live-action photography and 40% flat motion-graphics overlay: thin white measurement lines, fluorescent lime-green geometric shapes, small monospaced numbers and short UI ticks drawn crisply over the footage, never as glowing blobs. Shot after rain on wet asphalt with strong reflections, high contrast, shallow depth of field, real skin texture and visible sweat, no beauty filter. Accent color is fluorescent lime green, supported by black, white and a little cyan. The recurring runner is a Japanese woman in her late twenties with black hair in a single ponytail, a black long-sleeve top with a lime-green stripe, black tights, and white-and-lime running shoes. Preserve her exact face, hairstyle, outfit and colors throughout; never redesign her.

[Shot 1] An extreme close-up of a running shoe striking wet asphalt. The sole compresses, water sprays sideways in slow motion, then the numerals "00:00" resolve on the road surface as if projected onto it. The camera pedestals up with small amplitude at slow speed.

[Shot 2] At 00:01.500, the camera cuts to a side view of the runner at full stride along an empty street. A thin white line traces the length of her body, then the lime-green text "5'12"/km" locks beside her shoulder and follows her, then small tick marks stream past behind her. The camera trucks left with large amplitude at fast speed, keeping pace with her.

[Shot 3] At 00:03.000, the camera cuts to a split screen of two vertical halves — her profile exhaling on the left, her feet landing on the right. A lime heartbeat waveform runs down the dividing line, spikes once, then settles into a steady rhythm. Static shot.

[Shot 4] At 00:04.500, the camera cuts to a wide shot of her crossing an empty intersection. Concentric lime rings expand outward from her feet, then small distance tags fly up and stick to the surrounding buildings one at a time, then the rings fade. The camera arcs with large amplitude at slow speed around her.

[Shot 5] At 00:06.000, the camera cuts to an extreme close-up of her jaw and shoulder in high speed as sweat flies off her skin. Fast-counting monospaced numbers sweep across the frame, blur past, and snap to a stop. The camera shakes slightly with small amplitude at fast speed.

[Shot 6] At 00:07.200, the camera cuts to a long outdoor staircase seen from below as she sprints up it. Lime rectangles light up on each step behind her, one after another, until the whole flight is lit. The camera tilts up with small amplitude at fast speed.

[Shot 7] At 00:08.400, the camera cuts to a top-down aerial view of the city blocks. Her route draws itself as a single continuous lime line across the streets, curves around a corner, and reaches a small marker where she is still running. The camera pulls out with large amplitude at fast speed.

[Shot 8] At 00:09.600, the camera cuts to a front tracking shot of her running straight at the lens. The huge white word "FASTER" slams across the frame and holds fully readable, then she reaches it and runs straight through the letters, which break apart behind her. The camera pushes in with large amplitude at fast speed.

[Shot 9] At 00:10.800, the camera cuts to a bridge where she slows to a stop, plants her hands on her hips and exhales hard, breath visible in the cold air. Every number seen earlier flies back into frame and converges beside her into one large lime figure reading "-0:47", then a ring of light expands outward from it across the bridge. The camera pushes in with small amplitude at slow speed.

[Shot 10] At 00:13.000, the camera cuts to a pure black frame. One thin lime line sweeps horizontally across it, the white logotype "PACE" resolves at the center, and the Japanese line "走った分だけ、記録は動く。" appears in small white type beneath it. Hold the lockup cleanly until exactly 15.000 seconds. Static shot.

Editing: fast and precise — hard cuts on the beat, speed ramps between slow motion and real time, whip pans and snap zooms. Every cut must feel compositionally different. All graphic overlays and text stay fully readable and are never hidden behind the runner or the buildings. No anime or illustration rendering, no 3D render, no lens-flare storms, no browser interface, no player controls, no subtitles, no captions, and no text other than the strings named above. Exactly 10 cuts.

overall_soundscape:

Wet footfalls slap the asphalt and water sprays with each stride, under steady controlled breathing and a low night wind. Short UI ticks mark the numbers as they lock into place, a metal staircase rings under her steps, and a soft chime sounds as the figures converge on the bridge. No dialogue.

non_diegetic_music:

An original 15-second electronic track built on a low pulsing sub bass and a tight hi-hat pattern at a driving tempo. Start sparse and dark, add layered percussion from 00:06.000, open into a bright wide chord at 00:10.800, and close on a single clean synth note that resolves at 15.000 seconds.
