frei0r

frei0r is a software project that provides a simple API for video effects. It allows developers to create and share plugins that can be used in various video editing and processing applications. The core idea behind frei0r is to offer a standardized way to implement video filters, making them easily portable and accessible.

The frei0r API is designed to be lightweight and easy to integrate. This has led to its adoption by several popular open-source video tools. Applications that support frei0r can load and apply these plugins to video streams, enabling a wide range of visual transformations. These effects can include color adjustments, blurs, distortions, and many other creative manipulations.

The frei0r plugin system promotes a modular approach to video effects. Users can often download and install new frei0r plugins independently of the main application, expanding their creative options. The project emphasizes simplicity and efficiency, aiming to provide a robust framework for real-time video processing without excessive overhead. Its open-source nature encourages community contribution, leading to a growing library of available effects.
