- Install:
npm install gl-transitions - Registry: gl-transitions · Framework: glsl · License: MIT
- Docs and preview: https://gl-transitions.com/editor/BurnThrough
- Source: https://github.com/gl-transitions/gl-transitions/blob/master/transitions/BurnThrough.glsl
- Example: https://skills.varg.ai/previews/lib-gl-transitions-burn-through.mp4?v=55183 (Rendered by varg from the library’s own code (GL Transitions · rendered by varg))
- Time: Seek-safe. Time is an input, so frame N always renders the same. Drop it into a render as it is.

Add the "BurnThrough" transition from GL Transitions (by liubailin2020, MIT; https://gl-transitions.com/editor/BurnThrough, GLSL source https://github.com/gl-transitions/gl-transitions/blob/master/transitions/BurnThrough.glsl) on a dramatic cut, for example into the reveal or the end card: 1.2 s, linear progress. It reads like paper catching fire. Remotion: npm install gl-transitions @gl-transitions/remotion @remotion/transitions, then a <TransitionSeries.Transition> with presentation={glTransition({ name: "BurnThrough", params: { burnColor: [1.0, 0.5, 0.0] } })} and timing={linearTiming({ durationInFrames: 36 })} (36 frames at 30 fps). HyperFrames: draw the GLSL on a full-frame WebGL canvas over the cut, with the outgoing and incoming frames as the from/to textures, and compute progress from the composition time, clamp((t − cutStart) / 1.2, 0, 1); never from requestAnimationFrame or a timer, so every frame renders the same. ffmpeg's xfade can't run GLSL. burnColor is the edge glow as RGB (vec3(1.0, 0.5, 0.0) is orange; vec3(0.3, 0.6, 1.0) gives an electric blue).
