Polish
44 ways to move between scenes
A cinematic transition library, Ken Burns motion, green-screen keying, and a full set of color and geometry filters — the finishing effects, all driven by JSON with no timeline required.
Effects
A creative toolkit in the payload
Zvid’s render payload carries a rich set of visual effects. There are 44 named FFmpeg transitions — fades, wipes, slides, smooths, geometric reveals, slices, and more — and the same library works two ways: as scene-to-scene transitions and as entrance/exit animations on any individual element.
Beyond transitions, every element supports Ken Burns zoom, green-screen chroma key, color filters (brightness, contrast, saturation, hue, blur, invert, tint), crop, rounded corners, rotation, flip, and opacity — with timed enter and exit. It’s an editor’s worth of polish, expressed entirely as data.
What you get
Cinema-grade, as data
44 transitions
Fades, wipes, slides, smooths, geometric reveals, diagonals, slices, dissolve, pixelize, radial, and more.
Two ways to use them
The same effects work as scene-to-scene transitions and as per-element entrance and exit animations.
Ken Burns motion
Add a slow zoom to any image or clip — a boolean, or a depth from 1 to 10 for how far it pushes in.
Green-screen keying
Chroma key any element by color with tunable similarity and blend to drop backgrounds cleanly.
Color filters
Brightness, contrast, saturation, hue-rotate, blur, invert, and color tint — all per element.
Geometry controls
Crop, rounded corners, rotation from −360° to 360°, horizontal/vertical flip, and opacity.

Frequently asked questions
Can transitions animate a single element? +
Yes. Every transition doubles as an entrance or exit animation for an individual element — the element is cross-faded against a transparent background.
Do I need the editor to use effects? +
No. Effects live in the JSON payload, so you can apply them purely through the API. The editor’s effects gallery is just a visual way to pick them.
Is Ken Burns configurable? +
Yes — enable it as a boolean for a default push-in, or set a depth from 1 to 10 to control how dramatic the zoom is.
