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.

Editly has a simple CLI for quickly assembling a video from a set of clips or images, or you can use its more flexible JavaScript API.

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.

Use-cases

  • Create a slideshow from a set of pictures with text overlay
  • Create a fast-paced trailer or promo video
  • Create a tutorial video with help text
  • Create news stories
  • Create an animated GIF
  • Resize video to any size or framerate and with automatic letterboxing/cropping (e.g. if you need to upload a video somewhere but the site complains Video must be 1337x1000 30fps)
  • Create a podcast with multiple mixed tracks
