Package Exports

etro
etro/src/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (etro) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Etro

A video editor for developers

Screenshot

Etro is a completely in-browser video-editing library. Similar to conventional video-editing software, it lets you layer media and other content on a timeline. Audio, image, video and other tracks are supported, along with powerful video and audio manipulation to existing tracks. Being very flexible and extendable, you can choose to only use the core components or define your own.

Features

Export video to blob
Write your own layers and effects
Write a function for a property

Built-in hardware accelerated visual effects

Usage

<script src="https://unpkg.com/etro@latest/dist/etro.js"></script>

Then, to create a movie (which is a project)

const movie = new etro.Movie(canvas);

Then, add layers

movie
  // add an empty blue layer starting at 0s and lasting 3s and filling the entire screen
  .addLayer(new etro.layer.Base(0, 3, {background: 'blue'}))
  // add a cropped video layer starting at 2.5s
  .addLayer(new etro.layer.Video(2.5, video, {mediaX: 10, mediaY: -25}));

To start the movie, just like any ol' <video> or <audio>, use .play()

movie.play();
