Editly is a tool and framework for declarative non-linear video editing. Rather than arranging clips on a conventional graphical timeline, you describe the finished video using command-line arguments or a JavaScript/TypeScript API.
The software uses FFmpeg for media processing and is particularly well suited to automated video generation. Clips, images, titles, subtitles and audio can be assembled programmatically, making Editly useful for slideshows, promotional videos, tutorials and other repeatable production workflows.
A declarative configuration controls the output dimensions, frame rate, individual scenes, transitions, overlays and audio. Input media is automatically scaled and letterboxed or cropped where necessary to match the requested output.
This is free and open source software.
Key Features
- Create videos using a command-line interface or declarative JavaScript/TypeScript API.
- Combine video clips, still images, text, subtitles, audio and generated backgrounds.
- Automatically scale, crop and letterbox source material to different output dimensions and aspect ratios.
- Control clip duration and automatically speed up or slow down source video to fit a scene.
- Overlay text, transparent images, video with alpha channels and picture-in-picture content.
- Create dynamic overlays using HTML5 Canvas and Fabric.js.
- Render custom OpenGL shaders for generated visual effects.
- Mix multiple audio sources with automatic crossfading, ducking and normalization.
- Create B-roll sequences by showing different sub-clips during a scene.
- Generate MP4 video or animated GIF output.
- Define complete edits using JSON or JSON5 configuration files for repeatable automated rendering.
