ISF is a format that allows anyone to create cool shader effects and share them. And you will be able to import them in Coollab 2.0!


Browse the official ISF library, download the shader you like, drop it into Coollab, and it just works. It becomes a regular node in your graph, with all its settings exposed as pins.

Multi-pass effects (Blur, Feedback)​


Hover to play

In Coollab v1, your whole project was compiled down to one single big shader. This was simple enough and worked well for a while, but it has some limitations: some effects fundamentally need to draw an intermediate image first, then read it back.

The v2 engine chains as many rendering passes as an effect needs, and can keep previous frames around. This unlocks:

Transition effects​


Hover to play

ISF has a special syntax to define Transitions between two images. This is perfect for our new VJ switcher where you can easily transition between clips on the fly, now with all the funky transitions you never dreamt of!

Generators​


Hover to play

Some ISFs define fully standalone image generators which can be used as a scene on their own.

Inside Coollab we will just use generators to define some noises and other basic textures, because our philosophy is to be a creation tool, not one that just gives you a thousand prebuilt scenes to pick from. But if you want to, you can definitely import some cool scenes from the official ISF library!

What's next​

The rendering engine is in very good shape, so we are starting to work on the UI right now. Still aiming for a first alpha version somewhere between October and December. In the meantime you can expect more posts showcasing the work we did this summer on our 3D renderer and our Text renderer.

For the past 10 months we have been preparing this completely redesigned and improved version of Coollab! The goal is to remove the limitations of the previous codebase to enable many new features that we (and maybe you!) have been wanting for years! This will make Coollab a much more versatile software than it is today!

Proper VJ setup​


Inspired by Resolume, you will finally have a dedicated UI to group all your scenes and switch between them:

Groundwork for new effects​


The internal engine has been redesigned to be much more generic, opening the door to whole new categories of effects beyond what was possible with the shader-only approach of v1.

You will not get all of these day one, but the infrastructure is here to add them easily over time! We are right now working on 3D Meshes and Text rendering!

More outputs​


Again, you will not get all of these day one, but we are laying the ground work for them!

What's next​

\n

Coollab 2.0 is not quite ready to be released yet, but we are working very hard on it! We have chosen to take our time to lay a sound technical foundation and build a high-quality software, rather than rushing to release it as fast as possible, and then having to pay the consequences of a buggy and clunky codebase forever.

\n

We are aiming to release a first alpha version somewhere between September and December. In the meantime you can expect many more blog posts coming soon, showcasing the progress we have made so far, and covering some of the cool technical details!
