Kino

Kino is an easy-to-use, proof of concept package for creating animations in pure Typst. Kino comes with a companion script kino.py for exporting to videos, slideshows, or reveal.js presentations. See the manual and the examples.

Examples

Installation

To use the Kino package, simply add the following code to your document:

#import "@preview/kino:0.1.0": *

The companion python script kino.py can be downloaded from the homepage. It requires python3, pypdf, ffmpeg and typst. A flake is also provided for nix users.
To use reveal.js exports, an installation of reveal.js is also required.

Quick start

Create a file quick_start.typ with the following content:

#import "@preview/kino:0.1.0": *
#set page(width: auto, height: auto)

// main show rule
#show: animation

// initialize an animation variable
#init(x: (3cm, 2.))

// animate x, for a duration of 1 second
#animate(x: (0cm, 3))

// then animate x using a sine transition
#then(transition: "sin", x: (1cm, 1))

// meanwhile animate y pointwise from the initial value t => 0, for a duration of 2 seconds.
#meanwhile(duration: 2, y: t => (2cm * t))

// context is mandatory to evaluates animation variables
#context {
  // evaluate x
  let (w, h) = a("x")

  // evaluate y
  rect(width: w, height: a("y")(h))
}

// mandatory
#finish()

By default, this Typst code compiles to a pdf containing frames of the animation, at 5 frames per seconds. To generate a 35 fps video, use the script kino.py along with the following arguments:

python3 kino.py quick_start.typ video --fps 35
