V8 engine assembles and ignites
A V8 engine assembly animation: hundreds of parts build the block, then thermal windows show it ignite. Copy the prompt into Claude and render the MP4.
A bare black engine block turns on a grey seamless, shown cold in a thermal window. Parts fly in across fast cuts as bolts torque in sequence and a counter races to the target. It fires, headers glow, a section cut shows piston, valves and spark, and it idles under the brand.
Change the hook and ignition headlines, brand, parts counter target, and the warm, cool, amber and backdrop colours. At 9:16 and 15 seconds with sound, it suits engine builders, tuning shops and car channels on Reels, TikTok and Shorts.

What happens, beat by beat
- 0.00: grazing macro across a machined deck, bores receding into shallow focus, hard rim strip. Headline slams in at 0.18 (from below, scale 1.18 to 1, 0.1 s, expo out), exits at 1.74.
- 0.90: high 3/4 on the bare block yawing on a turntable; a thermal window scans down at 1.0 reading "-3°C".
- 2.00: block upside down; a swarm streaks in from every side and the crank drops into the saddles, landing crisp at 2.30 with shake and glints on the copper shells. Counter slides in.
- 2.55: low macro down the crank axis: five main caps slam 0.055 s apart, ten cap bolts screw down and flash.
- 3.10: wide: the block rolls 180 degrees upright with weight and a damped overshoot; second swarm.
- 3.62: eight mirror pistons plunge into their bores in sequence.
- 4.20: copper gaskets land, heads slam at 4.36 and 4.46.
- 4.72: overhead: 20 head bolts torque in the real spiral order, centre out, each with a glint.
- 5.50: cam covers slam, eight chrome velocity stacks drop in, coil packs click, fuel rail and loom follow.
- 6.12: headers swing in about the collector end; flange bolts torque.
Materials and light
- Black oxide: MeshPhysicalMaterial metalness 0.85, roughness 0.2, full clearcoat, in a dark jewellery-studio environment (near-black room, two hard vertical strips, a hot top card, a broad overhead strip) drawn on…
- Machined and chrome parts get a second, brighter grey-room env so they read as steel. Copper gaskets and shells are the only warm metal. Rotate the env per shot so…
- Engine-space cavity occlusion darkens the crankcase and bores.
- After the catch, headers heat-tint along their length (red port glow, straw, bronze, purple, blue) with emissive ports and orange bounce lights.
How the prompt opens
Make a 15-second, 9:16 (1080x1920), 30 fps product film in Three.js with its own sound. A bare black cast engine block turns on a grey studio seamless while a thermal window shows it stone cold. Hundreds of parts fly in and the engine assembles in real mechanical order across fast cuts, every bolt torquing in sequence while a counter races to [your part count, e.g. 400]. It fires, thermal windows show heat spreading to glowing headers, a section cut shows piston, valves and spark in slow motion, and it ends idling under [your brand, e.g. an invented engine maker called VARGA V8]. Swap in your own product, words, count and colours.
