Hot glowing holes or a flare burn across A like overheated film and reveal B.

What it does

Built on FilmBurn by anastasia-dunbar (gl-transitions), MIT. The write-up and recipes below are varg's.

Bright orange-white burn edges eat the frame; the next shot shows through the burnt areas.

When: Vintage, music video, documentary archive, dramatic chapter changes.

Watch out: Mixing it with clean modern UI footage; it reads as a theme clash.

Timing: 0.5–1.0 s (CapCut Film Burn 0.7 s, Burn 0.47 s)

Also called: Film Burn, Burn, film burn transition, burn through, ember burn

In FFmpeg

No built-in burn. Screen-blend a film-burn overlay clip over a crossfade (same pattern as the Light Leak card), or run GL FilmBurn/BurnThrough via editly (1.x names FilmBurn, burn0).

In HyperFrames

Shader ridged-burn from @hyperframes/shader-transitions placed at the cut (t = 4 s):

<div id="s1" class="scene" style="background:#0a0a0a"><video src="a.mp4" muted playsinline></video></div>
<div id="s2" class="scene" style="background:#0a0a0a"><video src="b.mp4" muted playsinline></video></div>
<script src="https://cdn.jsdelivr.net/npm/@hyperframes/shader-transitions/dist/index.global.js"></script>
<script>
  const tl = HyperShader.init({ bgColor: "#0a0a0a", scenes: ["s1", "s2"],
    transitions: [{ time: 4, shader: "ridged-burn", duration: 0.7 }] });
  window.__timelines = window.__timelines || {}; window.__timelines["main"] = tl;
</script>

Each .scene needs an explicit background-color equal to bgColor. Or install the ready block: npx hyperframes add ridged-burn.

In Remotion

import {TransitionSeries, linearTiming, springTiming} from '@remotion/transitions';
import {filmBurn} from '@remotion/transitions/film-burn';

<TransitionSeries>
  <TransitionSeries.Sequence durationInFrames={90}><ShotA /></TransitionSeries.Sequence>
  <TransitionSeries.Transition presentation={filmBurn({seed: 1})} timing={linearTiming({durationInFrames: 24})} />
  <TransitionSeries.Sequence durationInFrames={90}><ShotB /></TransitionSeries.Sequence>
</TransitionSeries>

Total = 90 + 90 - 24 frames: the transition overlaps the two shots. Shader presentations are built on Remotion's HTML-in-canvas: renders work out of the box (--gl=angle, or --gl=swangle without a GPU); the Studio preview needs Chrome with chrome://flags/#canvas-draw-element enabled.

In CapCut

Transitions tab → Light Effect → Film Burn, Burn. Desktop: drag the tile onto the cut between two clips and set Duration in the right panel ("Apply to all" reuses it on every cut). Mobile: tap the small white square between clips, pick the transition, drag the duration slider, tap ✓. Tab labels and placement change between versions and regions.
