For today's guest post we're joined by eatyourwork who first introduced us to the possibilities of using OhmRGB Slim alongside of VDMX in a blog post a couple of years ago. Since then we've made a few basic templates for new video performers to get started with a simple VJ video mixer setup with the Ohm, but in this video tutorial Simas shows off the extent to which you can customize your layout and MIDI mapping when making your own video performance rig.Read More
When compositing layers of video together in VDMX or another VJ application, one of the standard techniques for combining images is the use of “masking images” which black out parts of an image by setting its transparency (alpha channel) to less than 1.0, allowing it to in front of content behind it instead of simply blending the two together.
This template is a variation on the technique described in the four channel mixer example in which we have two groups of layers (left and right bus) set up making it possible to preview and transition between mixes on the fly. Here the idea is similar, but instead of two mixes that use separate sets of clips, in this template each bus shares the same set of four clips, each with different controls for layer opacity, FX and blend modes. For an added twist, the four source for this template is used as a mask overlay for each bus that can be used in a variety of ways to combine the two separate mixes together in the main output.
In this video tutorial we quickly go through the design of this template and how it can be used to mix two movie clips along with an audio reactive or LFO driven Quartz Composer composition as an overlay or mask.Read More
The OhmRGB is a hardware MIDI controller from Livid Instruments for DJs and VJs with a nice mix of faders, knobs and buttons for triggering clips or FX. It's an especially useful controller to use with VDMX because it has a versatile layout which can be adapted for a variety of different setups ranging from simple DJ style two channel video mixers to advanced multiple layer compositions.Read More
