Hard cut, scale jump

Zero-frame hard cut between two framings of the same take (or to a B-roll shot with the presenter shrunk bottom-left); the pose and scale change but nothing blends. Sentence boundaries in talking heads where a jump cut should read as a deliberate beat, not a mistake.

Use this transition between my clips: "Hard cut, scale jump" from the 24fps video editor library.
Preset JSON: https://24fps.dev/video-editor/transitions/hard-cut-scale-jump-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 = { a, b }: two wrappers holding clip A and clip B, both filling the root. Clip A plays first; the cut happens at preset.at (3.6s) over preset.dur (0.15s), so start clip B at preset.at. Then const fx = mount(root, { kind: "transition", 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: swish at 3.27s on leads the Recess hard cut to B-roll by ~0.35 s (faint airy swish ~0.7 s, ~-20 dB, low confidence (hi-band burst at 3.27 in recess casual_vloggers)); boom at 3.39s on lands 0.1 s after the Vinyl jump cut at 3.29 (short low thump 25-90 Hz, ~0.15 s, sits under speech). In HyperFrames, fetch each with media-use (e.g. npx hyperframes media-use resolve --type sfx --intent "swish" --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.

Same idea: Also called: Recess (AI Edit), Vinyl II (AI Edit)
Technique: Jump cut on a sentence boundary, framing changes ~10-25% and captions re-flow after the cut.
