Plugin installation

Option 1 (Recommended):

Download it from from AE scripts: http://aescripts.com/bodymovin/

Option 2:

Or get it from the adobe store
https://creative.adobe.com/addons/products/12557
CC 2014 and up.

Other installation options:

Option 3:

  • download the ZIP from the repo.
  • Extract content and get the .zxp file from '/build/extension'

How it works

Here's a video tutorial explaining how to export a basic animation and load it in an html page

After Effects

  • Open your AE project and select the bodymovin extension on Window > Extensions > bodymovin
  • A Panel will open with a Compositions tab listing all of your Project Compositions.
  • Select the composition you want to export.
  • Select a Destination Folder.
  • Click Render
  • look for the exported json file (if you had images or AI layers on your animation, there will be an images folder with the exported files)

HTML

  • get the bodymovin.js file from the build/player/ folder for the latest build
  • include the .js file on your html (remember to gzip it for production)
<script src="js/bodymovin.js" type="text/javascript"></script>

You can call bodymovin.loadAnimation() to start an animation. It takes an object as a unique param with:

  • animationData: an Object with the exported animation data.
  • path: the relative path to the animation object. (animationData and path are mutually exclusive)
  • loop: true / false / number
  • autoplay: true / false it will start playing as soon as it is ready
  • name: animation name for future reference
  • renderer: 'svg' / 'canvas' / 'html' to set the renderer
  • container: the dom element on which to render the animation

It returns the animation instance you can control with play, pause, setSpeed, etc.

bodymovin.loadAnimation({
  container: element, // the dom element that will contain the animation
  renderer: 'svg',
  loop: true,
  autoplay: true,
  path: ‘data.json’ // the path to the animation json
});

Composition Settings:

Check this wiki page for an explanation for each setting.
https://github.com/bodymovin/bodymovin/wiki/Composition-Settings

Usage

animation instances have these main methods: anim.play()
anim.stop()
anim.pause()
anim.setSpeed(speed) -- one param speed (1 is normal speed)
anim.goToAndStop(value, isFrame) first param is a numeric value. second param is a boolean that defines time or frames for first param
anim.goToAndPlay(value, isFrame) first param is a numeric value. second param is a boolean that defines time or frames for first param
anim.setDirection(direction) -- one param direction (1 is normal direction.)
anim.playSegments(segments, forceFlag) -- first param is a single array or multiple arrays of two values each(fromFrame,toFrame), second param is a boolean for forcing the new segment right away
anim.setSubframe(flag) -- If false, it will respect the original AE fps. If true, it will update as much as possible. (true by default)
anim.destroy()

bodymovin has 8 main methods: bodymovin.play() -- with 1 optional parameter name to target a specific animation
bodymovin.stop() -- with 1 optional parameter name to target a specific animation
bodymovin.setSpeed() -- first param speed (1 is normal speed) -- with 1 optional parameter name to target a specific animation
bodymovin.setDirection() -- first param direction (1 is normal direction.) -- with 1 optional parameter name to target a specific animation
bodymovin.searchAnimations() -- looks for elements with class "bodymovin"
bodymovin.loadAnimation() -- Explained above. returns an animation instance to control individually.
bodymovin.destroy() -- To destroy and release resources. The DOM element will be emptied.
bodymovin.registerAnimation() -- you can register an element directly with registerAnimation. It must have the "data-animation-path" attribute pointing at the data.json url
bodymovin.setQuality() -- default 'high', set 'high','medium','low', or a number > 1 to improve player performance. In some animations as low as 2 won't show any difference.

Events

  • onComplete
  • onLoopComplete
  • onEnterFrame
  • onSegmentStart

you can also use addEventListener with the following events:

  • complete
  • loopComplete
  • enterFrame
  • segmentStart
  • config_ready (when initial config is done)
  • data_ready (when all parts of the animation have been loaded)
  • DOMLoaded (when elements have been added to the DOM)
  • destroy

Other loading options

  • if you want to use an existing canvas to draw, you can pass an extra object: 'renderer' with the following configuration:
bodymovin.loadAnimation({
  container: element, // the dom element
  renderer: 'svg',
  loop: true,
  autoplay: true,
  animationData: animationData, // the animation data
  rendererSettings: {
    context: canvasContext, // the canvas context
    scaleMode: 'noScale',
    clearCanvas: false,
    progressiveLoad: false, // Boolean, only svg renderer, loads dom elements when needed. Might speed up initialization for large number of elements.
    hideOnTransparent: true //Boolean, only svg renderer, hides elements when opacity reaches 0 (defaults to true)
  }
});

Doing this you will have to handle the canvas clearing after each frame
Another way to load animations is adding specific attributes to a dom element. You have to include a div and set it's class to bodymovin. If you do it before page load, it will automatically search for all tags with the class "bodymovin". Or you can call bodymovin.searchAnimations() after page load and it will search all elements with the class "bodymovin".

  • add the data.json to a folder relative to the html
  • create a div that will contain the animation.

**Required**
. a class called "bodymovin" . a "data-animation-path" attribute with relative path to the data.json
**Optional**
. a "data-anim-loop" attribute . a "data-name" attribute to specify a name to target play controls specifically
**Example**
```html
```

Preview

You can preview or take an svg snapshot of the animation to use as poster. After you render your animation, you can take a snapshot of any frame in the animation and save it to your disk. I recommend to pass the svg through an svg optimizer like https://jakearchibald.github.io/svgomg/ and play around with their settings.

Recommendations

Files

If you have any images or AI layers that you haven't converted to shapes (I recommend that you convert them, so they get exported as vectors, right click each layer and do: "Create shapes from Vector Layers"), they will be saved to an images folder relative to the destination json folder. Beware not to overwrite an exiting folder on that same location.

Performance

This is real time rendering. Although it is pretty optimized, it always helps if you keep your AE project to what is necessary
More optimizations are on their way, but try not to use huge shapes in AE only to mask a small part of it.
Too many nodes will also affect performance.

Help

If you have any animations that don't work or want me to export them, don't hesitate to write.
I'm really interested in seeing what kind of problems the plugin has.

AE Feature Support

  • The script supports precomps, shapes, solids, images, null objects, texts
  • It supports masks and inverted masks. Maybe other modes will come but it has a huge performance hit.
  • It supports time remapping
  • The script supports shapes, rectangles, ellipses and stars.
  • Expressions. Check the wiki page for more info.
  • Not supported: image sequences, videos and audio are not supported
  • No negative layer stretching! No idea why, but stretching a layer messes with all the data.

Notes

  • If you want to modify the parser or the player, there are some gulp commands that can simplify the task
  • look at the great animations exported on codepen See examples on codepen.
  • gzipping the animation jsons and the player have a huge reduction on the filesize. I recommend doing it if you use it for a project.
