Defocus pulse snapping into focus
At ~0.17 s the whole frame blurs heavily (about 70% sharpness loss) and snaps back sharp in ~0.2 s as the first lowercase caption lands. Clip openers that want a tiny 'camera finds focus' hit instead of a flash.

Apply this to my video: "Defocus pulse snapping into focus" from the 24fps video editor library.
Preset JSON: https://24fps.dev/video-editor/effects/defocus-pulse-snap-focus-open-e5x/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).
Sound design: boom at 0.15s on blur peak at 0.17-0.2 s (streetwear_fashion_creators SUB +24 dB at 0.15) (very short low thump ~0.1 s); swish at 0.16s on first word lands (faint, hi band +16 dB, low confidence). In HyperFrames, fetch each with media-use (e.g. npx hyperframes media-use resolve --type sfx --intent "boom" --project .; media-use needs `heygen auth login`, without it use `--local-only`, check with `--doctor`); elsewhere use royalty-free SFX or ones I give you.
