Editly
Editly is a headless, programmatic video engine and automated assembler. It functions as a declarative video editor that generates MP4 and GIF exports from structured data or code, removing the need for a manual graphical user interface.
The system is distinguished by its ability to integrate GLSL fragment shaders as visual layers within a programmatic timeline. It uses a configuration-based model to define clips, layers, and audio tracks, allowing for reproducible video assembly and the generation of custom programmatic graphics.
The engine covers a broad range of media production capabilities, including non-linear video sequencing, asset rescaling, and multi-track audio mixing with automatic normalization and ducking. It handles visual composition through canvas-based rendering for text overlays, subtitles, and camera simulation effects like zooming and panning.
The rendering engine and its dependencies are available as a containerized image for consistent execution across environments.
