Use filters for image and video editing

When it comes to image and video editing, there’s nothing like applying a filter. Filters enable you to perform all kinds of digital processing – from simple corrections and fixes to transformative special effects – on your movies and photos, and you’ll find most video and image editors come with a selection built-in.
G’MIC – or GREYC’s Magic for Image Computing – is an open-source framework providing tools for creating such filters. Thanks to the efforts of dozens of volunteers, the G’MIC language has been used to develop hundreds of filters for both images and video, and its collections are expanding all the time.
G’MIC can be used several different ways. You can install it as a standalone tool to run from the shell – in this guise it’s effectively an interpreter for running the G’MIC language. But it’s also available as a QT-based plugin, which makes it possible to incorporate over 500 different filters into GIMP and Krita, which will be the main focus of this tutorial. We’ll also reveal how you can use G’MIC filters to transform video clips using the open-source Flowblade tool.
Support for G’MIC is built into both and – no need to download or install anything. That’s the theory, at any rate. The problem is that both and don’t ship with the latest version of G’MIC, and while that’s not necessarily a problem for (the version of the plugin shipped with the latest 5.x release – 3.0.0 – works fine), you’ll find that if you install via snap, you’ll be stuck with a plugin – 2.9.6 – that throws up multiple errors with the smart preview on various filters.
