Lighter strike with thermal windows

A 9:16 lighter strike animation: the lid snaps open, sparks fly, a flame blooms, thermal windows read the heat. Copy the prompt into Claude and render it free.

A glossy black flip-top lighter sits on a grey seamless. The lid snaps open, the flint wheel turns in slow motion and throws a fan of sparks, then a soft yellow flame blooms. The lid slams shut and the flame dies in a curl of smoke. Gradient rectangles slam in on the cuts, recolouring what is behind them like a thermal camera, each with a live temperature readout.

Ask Claude to change the brand on the end card, the strike headline, and the spark, flame and lid temperatures. The three window colours and the studio backdrop are editable too. At 1080x1920 and 12 seconds, it suits Reels, TikTok and Shorts, plus vertical product launches and ad teasers.

Specs

What happens, beat by beat

  1. 0.00 to 0.80, cold open. Closed lighter on frame 0, 3/4 front, slow push. A window on the right half reads CASE 21°C, slides off at 0.56.
  2. 0.80 to 2.00, snap. Macro side-on to the hinge. Lid flips open at 1.10 in 0.24 s with a cam-click overshoot and camera shake; a highlight rakes across; pull back to the chimney.
  3. 2.00 to 3.25, wheel. Extreme macro on the knurl, razor-thin focus. The wheel turns by itself; first sparks at 2.6. [Headline] in white condensed type near the top from 2.15 to 3.2.
  4. 3.25 to 3.80, sparks. Wheel big in the foreground, the fan flying away. A window drops from the top: SPARK MAX [3,000]°C, sparks white-hot inside.
  5. 3.80 to 4.50, fountain. Front, slightly low; sparks pour out of the chimney and flicker through the holes. A window slides in from the left, exits up at 4.32.
  6. 4.50 to 6.25, bloom. Down the chimney onto the wick: blue bead at 4.55, then crane up as it blooms. At 5.75 a window counts FLAME CORE from 21 to [1,200]°C.
  7. 6.25 to 7.75, flame hero. Low 3/4 wide, lateral slide. A window anchored to the flame splits it: left half thermal layers, right half the real flame with shimmer.
  8. 7.75 to 9.00, flame macro. Chimney top, blue base glowing through the holes. A full-width heat band climbs the flame in three steps (8.0, 8.33, 8.66).
  9. 9.00 to 10.00, shut. The lid slams at about 9.41 with a rebound and shake; the flame bends and dies; smoke rolls off the lid. A lid-anchored window reads LID [64]°C, cooling.
  10. 10.00 to 12.00, hero. Slow 10-degree orbit, smoke curl above. The etched [brand] glows ember orange with leftover heat from 10.2, then cools. A last small window crosses the lid 11.0 to 11.55; final 0.4 s…

How the prompt opens

Make a silent 12-second, 9:16 (1080x1920, 30 fps) product film in Three.js. A glossy black-oxide flip-top lighter sits on a soft grey seamless. The lid snaps open, the flint wheel turns by itself in slow motion and throws a fan of sparks, a soft yellow flame blooms, then the lid slams shut and the flame dies in a curl of smoke. Flat gradient rectangles slam in on the cuts and re-colour what is behind them like a thermal camera, each with a live temperature readout. The brand is an invented example (e.g. a lighter brand called EMBR). Expose as variables: [your brand], [headline, e.g. ONE STRIKE.], [spark temperature, 3,000°C], [flame temperature, 1,200°C], [lid temperature, 64°C], [window orange #F26B1D], [window blue…
