空飛ぶ車 AI 動画生成 愛車があのスロープを逆さまに走る

2026年10月15日、テスラは SpaceX のマクレガー試験場で新型ロードスターを公開し、スタントを披露しました。車は巨大なフック型スロープを駆け上がって頂上で逆さまにぶら下がり、縁から飛び出すとコールドガススラスターで姿勢を立て直し、白煙の中に着地しました。その映像があまりに CG のように見えたので、自分の車を主役にした AI 版をつくる人が出てきました。このページは、あなたの写真と固定のプロンプト1つでその AI 版をつくります。テスラの映像も、車も、ロゴも使っておらず、テスラの製品でもありません。

上のボタンでつくる動画はすべて、下のプロンプトから生まれています。あなたの写真をただ1枚の参照画像として、Seedance 2.5 に送っています。モデルへの指示なのでプロンプトは英語のままです。好きな動画モデルにそのままコピーして使えます：

“A 15-second vertical video, photoreal night footage of a live stunt event at a test site, crisp and cinematic, like an official car reveal film.”

“The vehicle is the one in the reference photo: take only the vehicle, and its rider if someone is riding it, and leave the photo's background behind. It keeps its exact body shape, era, paint color, wheels, lights, stickers, dents and dirt from the photo; parts the photo does not show match its make and style; the license plate has no characters. If a person sits on it in the photo, like a motorcycle, scooter or bicycle rider, that person is part of the vehicle: they ride it in every shot from the first frame to the last, with the face, hair and clothes from the photo, gripping the handlebars; rider and vehicle move as one piece, and the vehicle is never riderless.”

“The place: a dark test site at night under a black sky, red lights along the ground. A giant hook-shaped stunt ramp seen from in front of it and to its left: a pale concrete face with a white center line and glowing red LED strips along both edges, a black steel scaffold tower behind its right edge. Its lower half is a slope, its upper half nearly vertical, and its top curls back over to the left.”

“The vehicle is one rigid object: from every angle, even upside down, its body, roof, wheels and proportions stay exactly as in the photo and never bend, stretch, squash, melt or change color.”

“Shot 1 (0-1s): A static wide shot, not a close-up, from about fifteen meters behind the vehicle and slightly to its right, the camera at roof height. Not straight behind: the camera is off to the right, so we see its whole back, and the rider's back if there is one, plus a thin strip of its right side. The vehicle is small in the frame, about half the frame wide, just left of center, between about 40% and 60% of the frame height. Above it the pale concrete ramp face towers up and fills the top of the frame, its red LED edge curving up on the left and its white center line on the right; below it a thin strip of lit concrete, then dark empty ground filling the whole bottom third of the frame, so the vehicle looks small under the towering ramp. It waits at the foot of the ramp, nose pointing up the ramp, tail lights glowing red, its headlights throwing a bright pool on the ramp ahead to the right. A very slight push-in.”

“Shot 2 (1-2.7s): Hard cut to a wide side view of the whole ramp from in front of it and to its left, the camera a little below the middle of the ramp: the ramp fills the upper two thirds of the frame, black ground below. From here to the end it is one continuous take with no cuts. The ramp's lower half is a slope, its upper half nearly vertical, and its top curls back over to the left. The vehicle sits small and still at the foot of the ramp, revving.”

“Shot 3 (2.7-8s): the vehicle accelerates up the ramp; the ramp curves from a slope to vertical and it stays stuck to the surface. On the overhanging top it hangs upside down under the ramp, wheels on the surface above, underside up and roof toward the ground; a rider hangs upside down with it, still in the seat gripping the handlebars. The camera stays in the same place and the whole ramp stays in frame, the vehicle small: it only tilts up slowly and zooms in a little near the top, keeping the vehicle in the upper third of the frame, until around 7.5s the top of the ramp is cut off by the top of the frame. Never a top-down view; the camera never flies along the ramp.”

“Shot 4 (8-9.3s): it leaves the lip still upside down, wheels up, its front toward the camera, drifting down beside the ramp. Thrusters on its underside fire short controlled bursts sideways and push it into a half barrel roll: it rolls as one rigid piece around its front-to-back axis, one side lifting first, the front staying toward the camera, any rider rolling with it in the seat. At about 8.6s it is on its side; by 9.3s it has rolled the rest of the way and is upright, wheels down. The roll takes about a second; it never flips forward or backward, and after it the vehicle stays upright. The camera pans left and down to follow.”

“Shot 5 (9.3-10.4s): upright, it sinks slowly on four strong jets pointing straight down from its four corners beside the wheels, with one sideways jet on each side holding it steady. The camera tilts down with it and the ramp leaves the frame on the right. At about 9.8s the jets hit the ground: white clouds burst up where they strike, spread out along the ground in every direction and billow upward.”

“Shot 6 (10.4-12.2s): it settles into the growing cloud and touches down on its wheels at 10.4s; the cloud rises above the wheels and then swallows it almost completely, a white cloud, brighter where its headlights hit it, with only a faint pink tint at the edges near the red ground lights. The camera comes down to ground level and swings round to its side.”

“Shot 7 (12.2-15s): it drives out of the cloud to the left in side profile, any rider still on it with their face in profile, smoke curling off its body and rolling behind it. The camera at ground level tracks left.”

“The gas behaves like real compressed cold air, like a CO2 fire extinguisher blast: each jet is a straight, forceful column, translucent pale blue-white at the nozzle, widening into a white fog cone further out, and pushes the vehicle the opposite way from where it blows. The jets do not glow: never orange, red or white-hot, no flames, no fire, and they cast no light. Where the jets hit the ground the gas spreads sideways and piles up into a dense white cloud that keeps rolling and drifting after the vehicle leaves; the cloud stays white, with only a faint pink tint at its edges near the red ground lights.”

“Constraints: nobody pushes or lifts the vehicle, no cables or cranes, no other people on screen. No subtitles, no text, no watermark, no logos.”

各段落の役割。最初の段落は、あなたの車（乗っている人がいればその人も）を写真のとおりに、しかも曲がらない一つの塊として保ちます。だから逆さまにぶら下がっても車体がゆがみません。ライダーについての一文がないと、テストではバイクが無人で戻ってきました。場所の段落は、スロープを文章だけで描きます。このページが送るのはあなたの写真だけだからです。秒数入りの7つのショットは、いちばんシェアされたリメイク動画のカット割りに沿っています。ガスの段落は、スラスターをロケットの炎ではなく冷たい空気のままにしておくためのものです。

限界もあります。姿勢を立て直す動きはモデル任せで、実車のように横方向へきれいに回転するのではなく、たいていは縁から前に傾いて離れ、振れながら水平に戻ります。赤い地面のライトで煙がピンクがかることがあります。ナンバープレートは無地になります。このページの動画は無音で、音は上の動画ページ版で付きます。
