Editly is a Free Video Editing Framework for Node.js

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

Features

• Edit videos with code! 🤓
• Declarative API with fun defaults
• Create colorful videos with random colors generated from aesthetically pleasing palettes and random effects
• Supports any input size, e.g. 4K video and DSLR photos
• Can output to any dimensions and aspect ratio, e.g. Instagram post (1:1), Instagram story (9:16), YouTube (16:9), or any other dimensions you like.
• Content is scaled and letterboxed automatically, even if the input aspect ratio is not the same and the framerate will be converted.
• Speed up / slow down videos automatically to match the cutFrom/cutTo segment length with each clip's duration
• Overlay text and subtitles on videos, images or backgrounds
• Accepts custom HTML5 Canvas / Fabric.js JavaScript code for custom screens or dynamic overlays
