Seriously.js
Seriously.js is a WebGL video processing framework and browser-based graphics engine designed for real-time video composition and image manipulation. It functions as a node-based visual compositor that organizes media sources and effects into a directed acyclic graph, using a custom fragment shader compiler to transform these graphs into optimized GLSL shaders for GPU-accelerated rendering.
The engine features a modular web media pipeline and a plugin-based architecture, allowing for the integration of custom effects, input sources, and output targets. It enables the development of interactive media compositions where user interface inputs can dynamically bind to shader variables to update visual effect properties in real time.
The framework supports multi-source media import from webcams, canvases, image files, and 3D engine outputs. Its processing capabilities cover visual effects such as color grading, blurring, distortions, and chroma keying, alongside tools for node transformation controls and the extraction of raw pixel data from any point in the processing chain.
