Inspired by ffmpeg-concat, editly is much faster and doesn't require much storage because it uses streaming editing. Editly aims to be very extensible and feature rich with a pluggable interface for adding new dynamic content.
What it does
Editly is a tool and framework for declarative NLE (non-linear video editing) using Node.js and ffmpeg. Editly allows you to easily and programmatically create a video from a set of clips, images, audio and titles, with smooth transitions and music overlaid.
How I built it
Using ffmpeg, Node.js and fabric.js
