Wavy, color-split ripples scramble the frame into psychedelic bands before the next shot settles

Prompt that renders it frame-exact

Add the "ButterflyWaveScrawler" transition from GL Transitions (by mandubian, MIT; https://gl-transitions.com/editor/ButterflyWaveScrawler, GLSL source https://github.com/gl-transitions/gl-transitions/blob/master/transitions/ButterflyWaveScrawler.glsl) in a music video or a trippy hook: 1 s, ease-in-out. The color separation reads as an analog glitch. Remotion: npm install gl-transitions @gl-transitions/remotion @remotion/transitions, then a <TransitionSeries.Transition> with presentation={glTransition({ name: "ButterflyWaveScrawler", params: { amplitude: 1.0, waves: 30.0, colorSeparation: 0.3 } })} and timing={linearTiming({ durationInFrames: 30, easing: Easing.inOut(Easing.cubic) })} (30 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, 0, 1) through the easing; never from requestAnimationFrame or a timer, so every frame renders the same. ffmpeg's xfade can't run GLSL. amplitude (1.0) and waves (30) shape the ripples, colorSeparation (0.3) the RGB split.
