ISF from Silvia Fabiani

One of the best parts of open specifications for file formats is that artists can create visual generators and FX for one piece of software and share their creations with others, regardless of what tools they use.

A few months ago we received an email from Silvia Fabiani asking if we could provide any tips for how to get started with remixing and writing her own shaders, and with a few links covering the basic ideas, she was ready to go. Over the following weeks we noticed that she had posted some of her own compositions on the ISF sharing site and we thought it'd be a great story to bring to the blog for an interview.

New VDMX Update With Improved Chroma Mask, Audio Analysis Visualizations and More!

Hey everyone!

We've released an update that includes a bunch of new features and other improvements – watch the video and read below to get the highlights on what's new!

If you want to jump right in, here's the download link: Download VDMX


Audio Analysis FFT and Waveform Values Published as Video

Using the FFT Color Lines generator to visualize the audio frequency spectrum and raw waveform

When an Audio Analysis plugin is active two new video streams are published that can be used by generators and FX to create new forms of music visualization.

The FFT and raw audio waveform are provided by the plugin as grayscale video streams that are 1 pixel tall. You can access them anywhere a video input menu is found such as a preview or masking FX.

To get started try using the new example FFT Color Lines and FFT Spectrogram ISF video generators.


New ISF Video FX

Earlier this year we released a new format for making custom generators and FX for VDMX called ISF. For this update we've created a bunch of our own new high end FX using the new format.

New film style "Lens Flare" FX

These are some of our favorites:

  • Updated Chroma Mask.fs, greatly improved color masking (eg. green / blue screen).
  • Color and Film FX: Chroma Desaturation Mask, Color Replacement, Ghosting, Bleach Bypass and Lens Flare.
  • Glitch FX: Collage, Convergence, Slit Scan and Pixel Shifter.
  • Geometry and Distortion FX: Optical Flow Distortion, Side Scroller and Flip, Shake and Shockwave Pulse.

Pro tip: Don't forget that you can also make your own ISF based generators and FX using these as example starting points!


Support for Generic HID Controllers

HID Input Plugin connected to SpaceNavigator

The HID Input Plugin interfaces with game controllers, 3D mice, and other devices that support the Human Interface Device (HID) protocol. Buttons, joysticks and sensors are made available to control UI items in VDMX like any other data-source. These can be a fun alternative to using a MIDI or OSC instruments.


Import / Export Control Surface Templates

Exporting a Control Surface layout to a JSON file

From the inspector panel of the Control Surface plugin you can export the layout and settings as a template file that can be easily imported into other projects or sharing standard layouts with other people.

Use the “Import JSON layout” and “Export JSON layout” buttons in the inspector to respectively load and save the templates.


Custom Movie Recorder Directory Paths

Enable the 'Custom export location?' toggle in the Movie Recorder Options panel

When using the Movie Recorder plugin to capture video and images, an optional custom folder location can now be specified in the inspector panel.

The default location for movie recordings can still be set in the VDMX Preferences – this new setting is an optional override for situations where the videos are further parsed or handled by another application or to make sorting the files easier.


Hope you enjoy these new additions and refinements! As always if you have any problems or suggestions send us a message by choosing “Report Bug” from the Help menu.

Once again, here's the download link: Download VDMX

Have a great weekend!

Introducing ISF Video Generators and FX

ISF stands for "Interactive Shader Format", and is a file format that describes a GLSL fragment shader, as well as how to execute and interact with it. The goal of this file format is to provide a simple and minimal interface for image filters and generative video sources that allows them to be interacted with and reused in a generic and modular fashion. ISF is nothing more than a [slightly modified] GLSL fragment shader with a JSON blob at the beginning that describes how to interact with the shader (how many inputs/uniform variables it has, what their names are, what kind of inputs/variables they are, that sort of thing). ISF isn't some crazy new groundbreaking technology- it's just a simple and useful combination of two things that have been around for a while to make a minimal- but highly effective- filter format.
