Using Shadertoy shaders with Videosync
With the arrival of Videosync 1.1 (released in April 2022) using ISF shaders in Ableton Live has become a lot easier. The new ISFLoader device allows you to open any ISF shader example that can be found on editor.isf.video.
There is no conversion or editing needed for this, just download the zip and drag the included .fs
file onto ISFLoader. Click here to see a video tutorial on how to do this and on how to map and control the shader parameters in Live.
But what might not be so evident, is that it is also possible to load most shaders found on Shadertoy.com into ISFLoader. This does require a little conversion, however. This article will discuss this conversion with a simple example.
