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.
This is free and open source software.
Features include:
- 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.
- Render custom GL shaders (for example from shadertoy).
- Can output GIF.
- Overlay transparent images or even videos with alpha channel.
- Show different sub-clips for parts of a clips duration (B-roll).
- Picture-in-picture.
- Vignette.
- Preserve/mix multiple audio sources.
