Split tone, amber over blue
Amber warmth in the top half of the frame fading into deep blue below. Landscapes and cityscapes where sky and ground should carry different moods.

Apply this to my video: "Split tone, amber over blue" from the 24fps video editor library.
Preset JSON: https://24fps.dev/video-editor/effects/split-tone-amber-blue-l4/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- Technique
