Converge and fuse
Labelled orbs drift, pressure pushes them together, they fuse in a flash and one result orb springs out with sparks.
Live loop · 7 s · 1920×1080 at 24 fps
Parameters
| Parameter | Type | What it does |
|---|---|---|
| text / radius / tilt | string / px / ratio | ring: the line in its centre after it lights; its half width (560) and tilt (0.34) |
| items / result | string[] / string | converge: 3-6 parts that come together and what they become |
| nodes | [{label, icon?}] | flow: 3-5 nodes in order; icon "page", "chat", "play", "check", "bolt", "gear", "box", "dot" |
| step_ms | ms | flow: node to node; converge: the hold before the pull |
| ease | {"<move>": ease} | retune any named move (see the entry's moves): a preset name ("out-expo"), a cubic-bezier [x1, y1, x2, y2], {spring: [hz, damping]} or {trapezoid: [accel, decel]}. A wrong move name or curve throws, it never falls back. A move measured from a reference clip (the replica workbench's measure/*.json, frame-keyed) becomes a curve without conversion: MV.fitEase(doc, "x", {from: 133, to: 142}) or `motion-fit <file> --measure x --from 133 --to 142 --ease` |
| camera | {focal?, x?, y?, z?} | the scene's camera: pan x / y and push z as numbers or keyframes [[ms, value, ease?], ...]; objects at different depths move differently (real parallax). focal default 1800 |
| brand | hexDefault: #6B5BFF | the site's brand colour; the component derives its accent (>= 3:1 on the stage), surfaces and ink from it |
| stage | "dark" | "light"Default: "dark" | the stage the component sits on |
| display | font stemDefault: "Inter-Bold" | headline stem; name it in the call so the runtime loads it |
| body | font stemDefault: "Inter-Regular" | UI / body stem; name it in the call so the runtime loads it |
| start_ms | msDefault: 300 | when the component starts, ms into the shot |
| background | booleanDefault: false | draw the stage background (off: transparent over the shot's own stage) |
| place | {x, y, w, h, z?} | the component's place in the shot's layout: it fits its 1920x1080 composition into this stage rect (centred, aspect kept); z orders components front to back. Default: the whole stage |
Moves and their curves
Every move is eased on its own. Retune one with ease: { "<move>": <curve> }, a curve name or cubic-bezier handles.
| Move | Curve | What it does |
|---|---|---|
| orb.pop | overshoot | each orb popping in |
| pull | in-cubic | the rig pulling the orbs in and twisting (accelerates into the meeting) |
| label.fade | out-quad | each label fading where it detached |
| push | in-out-sine | the camera pushing in during the pull (parallax between near and far orbs) |
| result.spring | {"spring":[1.67,0.7]} | the result orb springing out of the flash |
| result.label | house | the result's label fading in |
| spark.fly | out-expo | the sparks flying out and slowing |

MV.bind("s3", MV.energy(el, {"variant":"converge","items":["Script","Screens","Voice","Music"],"result":"Your film","brand":"#6B5BFF","stage":"dark","display":"Inter-Bold","body":"Inter-Regular"}));When to use it in a launch film
Many parts become one: tools into one app, assets into one film, inputs into one result.
Why it works
The squeeze builds tension, the flash releases it; the viewer sees 'all of these become this'.
Do not combine with
- more than six parts
- a result label longer than a few words
