Rainbow bokeh

Large soft discs in pink, cyan, yellow and violet float and pulse over the frame. Dreamy, festive ambience under a colour-cycling title.

Apply this to my video: "Rainbow bokeh" from the 24fps video editor library.
Preset JSON: https://24fps.dev/video-editor/effects/rainbow-bokeh-effect-cc2/preset.json (pass its "preset" to the engine).
Engine (MIT, no dependencies, ES module): https://24fps.dev/editor/engine.js. Download the engine next to your page (curl -O) rather than importing cross-origin, then import { mount } from "./engine.js" in a <script type="module"> served over http.
Wiring: root = a position:relative box at the video's size. media = { main }: main is a wrapper holding my video, filling the root. Then const fx = mount(root, { kind: "effect", preset, media }) and call fx.render(seconds) every frame. It is seek-safe: drive it from the GSAP timeline in HyperFrames or call render(frame / fps) in Remotion. Before capturing frames, await (fx.ready ?? document.fonts.ready).
Field reference: https://24fps.dev/video-editor/llms.txt. Keep sizes as fractions of the frame height so it works at any resolution. Credit: 24fps.dev/video-editor

Same idea: Also called: 七彩散光, Blurred Love, Bright Galaxy
Technique: Particle effect with the bokeh kind in several colours. Discs float across the whole frame and are not scattered from the letters.
Footage: Rainy street at night, Pexels
