Creating Video Feedback Loops on a Mac with VDMX

April 14, 2013

One of the most powerful techniques used to create real-time visuals and computer graphics going back to the early days of video is the use of feedback loops - the method of taking the current output and using it as a source frame in part of the next rendered frame. This incredibly useful process is particularly useful for Mac VJs and other graphic artists looking to find a unique look or style for their visuals, and is easily simulated within VDMX by using layer groups.

Chroma Key Basics

February 6, 2013

Chroma Keying is an image effects technique for compositing multiple video streams on top of each by applying a hue based masked to the foreground images. Commonly a blue or green screen is used in production for these purposes.

Within VDMX, using the 'Chroma Mask' FX on a layer will create a color-based mask that is applied within the FX-chain. Pixels in the input that are within the tolerance range are set to become transparent through the usage of alpha channels.

Assigning A Custom FX-Chain to a Clip

December 30, 2012

Using the File Inspector section of the Workspace Inspector individual clips can be tagged with attributes that override the source, FX, and composition settings of the layer that they are triggered on to. In this walkthrough we'll focus on the basic task of previewing a clip in the inspector and setting it to use a custom FX Chain.

The ECLECTIC METHOD REMIX, Part Two - Jamming

November 8, 2012

This is part two of a series with guest instructor Jonny Wilson of the Eclectic Method. You may want to start with the introduction post covering the overview of the workflow and the first topic on creating A/V samples.

In this tutorial we'll be looking at loading movie clips into VDMX and jamming on them using a MIDI controller.
