Seriously.js

Seriously.js is a real-time, node-based video compositor for the web. Inspired by professional software such as After Effects and Nuke, Seriously.js renders high-quality video effects, but allows them to be dynamic and interactive.

Getting Started

Full documentation is in progress at the wiki. Start with the Tutorial and FAQ.

Features

  • Optimized rendering path and GPU accelerated up to 60 frames per second
  • Accept image input from varied sources: videos, images, canvases and arrays
  • Effect parameters accept multiple formats and can monitor HTML form inputs
  • Basic 2D transforms (translate, rotate, scale, skew) on effect nodes
  • Plugin architecture for adding new effects
  • Read pixel array from any node
  • Load with AMD/RequireJS

Requirements

WebGL

Seriously.js requires a browser that supports WebGL. Development is targeted to and tested in Firefox (4.0+), Google Chrome (9+), Internet Explorer (11+) and Opera (18+). Safari is expected to support WebGL in the near future.

Even though a browser may support WebGL, the ability to run it depends on the system's graphics card. Seriously.js is heavily optimized, so most modern desktops and notebooks should be sufficient. Older systems may run slower, especially when using high-resolution videos.

Mobile browser support for WebGL is limited. Mobile Firefox and Chrome have decent support, but the Android Browser and Mobile Safari do not.

Seriously.js provides a method to detect browser support and offer descriptive error messages wherever possible.

Cross-Origin Videos and Images

Due to security limitations of WebGL, Seriously.js can only process video or images that are served from the same domain, unless they are served with CORS headers. Firefox, Chrome and Opera support CORS for video, but Safari and Internet Explorer do not, and videos served with CORS are rare. So for now, it is best to host your own video files.
