Forged Damascus knife from fire
A forged Damascus knife animation: a white-hot billet is folded, drawn, quenched and polished. Copy the prompt into Claude and render the MP4 free.
A glowing billet on an anvil is folded eight times under a hammer while a counter doubles up to 256 layers. It is drawn into a chef's knife, quenched, ground, etched and polished, then the blade falls through a tomato in slow motion and rests with the brand etched on it.
Change the etched brand, closing and polish headlines, fold counter word, forge temperature, three thermal colours and the studio backdrop. At 9:16 and 14 seconds with sound, it fits knife makers, tool brands and craft channels on Reels and Shorts.

What happens, beat by beat
- 0 to 2 s, hook. Low macro down the billet from one end, slow push in, embers drifting, glow reflected in the anvil face. At 0.42 s a thermal window slams in reading [forge temperature, e.g.…
- 2 to 5 s, eight folds over four shots. Each fold takes 0.375 s: the right half hinges 180 degrees over a tight radius, the hammer lands 0.27 s in, sparks burst, the stack squashes. A…
- 5 to 6.25 s, draw and quench. Top down, two strikes morph the bar into a glowing knife. At 5.70 s it goes tip-down into black oil: flame tongues, a steam burst, ripples, glow seen through…
- 6.25 to 7 s, cool. The blade rises out wet and turns, a single glint running down it. The readout counts 840 to 60°C as the window turns it from orange to indigo.
- 7 to 10 s, finish in fast cuts. The edge crosses a grinding wheel with a spark fan. A wet etch front glides heel to tip and the Damascus comes up behind it. A hard strip…
- 10 to 13 s, the cut. The knife falls edge first through a floating tomato in slow motion. The edge exits clean, juice beads fling off, and the halves fall open like a book.
- 13 to 14 s, hero. The knife drops onto the seamless with a tiny bounce and the camera pushes in from above. A small amber window crosses beside the logo and exits. Last line: [headline, e.g.…
Light, post and the thermal window
- Studio. A procedural environment sphere: a near-black room, two hard vertical strips and a hot top card. Rotate it per shot so a strip lands on the flats or streaks…
- Post. 4x MSAA HDR. Adaptive accumulation motion blur, with sub-frames from probed screen motion, up to 24. Gather depth of field. Bloom that fires on heat only. ACES on the…
- Thermal window. A rectangle fitted to the subject's screen bounds that slams in from a side in 0.16 s. Inside, map the steel's log radiance through an ironbow ramp: [cold…
What you can change
- Expose [brand], [headline], [polish line], [counter word], [forge temperature], the three ramp colours and [backdrop grey] as variables. Render every frame as a pure function…
How the prompt opens
Make a 14-second, 9:16 (1080x1920, 30 fps) Three.js product film with its own sound. A white-hot billet on a black anvil is folded eight times under a hammer, drawn into a chef's knife, quenched, ground, etched and polished. Then the blade falls through a tomato in slow motion and comes to rest on a grey seamless with [your brand] etched by the bolster. A thermal-camera window slides in on the cuts and re-colours whatever is under it. The brand is an invented example (e.g. a knife maker called KOVA); swap in your own.
