Our always-evolving setup

Some of the fun we have making live visuals comes from experimenting with always new ways of moving pixels and colors around our machines, eyes and screens. In other words, we often change how our equipment is connected and try different signal paths, like many others probably do. As we play with new setups, we Pixelflowers will share in this thread details about them and their pros and cons.

Equipment:
LZX Vidiot (analog video synthesizer); Roland Edirol V-8 (digital video mixer); Panasonic WJ-AVE5 (digital video mixer); Syntonie AVE MOD V2; BPMC Premium Cable; VideoMaster2000 (switcher with color/contrast controls); laptop running Resolume Arena; Korg Nanokontrol2; Easycap USB2AV capture card; salvaged webcam, TVCC, composite video splitter, video switcher, audio mixer, LCD display, CRT TV 15″

We like to have the Resolume output on a dedicated, unprocessed channel. We started making visuals with a Panasonic WJ-AVE5 mixer, which only has two channels, so our setups were relatively simple:

  • Vidiot Color Video > AVE MOD V2
  • AVE MOD V2 > BPMC Premium Cable
  • BPMC Premium Cable > WJ-AVE 5 #1
  • Resolume > WJ-AVE5 #2
  • WJ-AVE5 rec > Vidiot Luma In
  • Vidiot Luma Video > WJ-AVE5 ext. camera (superimpose effect)
  • 3 smartphones/tablets > audio mixer (they run a free app that works like an audio oscillator, generating sine frequencies of usually 0.5-2.5Hz / 49-51Hz / 99-101Hz respectively, which interfere beautifully with video frequencies)
  • Vidiot Luma > audio mixer
  • audio mixer > Vidiot (various inputs)
  • WJ-AVE5 > AV2USB > Linux computer running OBS > streaming

During 2020 we acquired an Edirol V-8 video mixer (which has 8 channels, each with a monitor output), a cheap projector, screens and a splitter. This allowed us to get more creative with the routing. Here’s how we connected our equipment last Wednesday, 11 November 2020:

(“output” and “input” are omitted; “#1” means “channel 1”)

  • Vidiot Color Video > V8 #1
  • V8 #1 monitor > VideoMaster2000 #1
  • Vidiot Luma Video > V8 #2
  • V8 #2 monitor > WJ-AVE5 ext. camera (superimpose effect)
  • WJ-AVE5 main > V8 #5
  • WJ-AVE5 rec > V8 #6
  • projector < TVCC > V8 #7
  • Resolume > V8 PC/8
  • V8 PC/8 monitor > video splitter
  • video splitter > 1: LCD display, 2: Vidiot Luma, 3: VideoMaster2000 #2
  • LCD display < webcam > Resolume
  • VideoMaster2000 > BPMC
  • BPMC > WJ-AVE5 #1
  • V8 preview > AVE MOD V2
  • AVE MOD V2 > WJ-AVE 5 #2
  • WJ-AVE 5 #2 monitor > TV 15″
  • 3 smartphones/tablets > audio mixer (they run a free app that works like an audio oscillator, generating sine frequencies of usually 0.5-2.5Hz / 49-51Hz / 99-101Hz respectively, which interfere beautifully with video frequencies)
  • Vidiot Luma > audio mixer
  • audio mixer > Vidiot (various inputs)
  • V8 main > AV2USB > Linux computer running OBS > streaming

Notes:

  • the TV 15″ acts as a preview monitor, but it’s affected by the AVE MOD V2. We may need another splitter
  • VideoMaster2000 color/contrast controls would be more useful at the end of the FX chain

thanks for sharing @pixelflowers - am enjoying the documentation of this setup !

if you were interested in ‘drawing’ some more the setup flows, there is an old thread talking about some tools here

we even have a plugin on scanlines that lets you do it - kind of forgot about this , might start a new topic on it, but in short can wrtie something like this:

[graphviz engine=circo]
graph {
    vidiot -> v4;
    resolume -> splitter -- v4;
    v4 -- avemod -- ave5 -- v4;
}
[/graphviz]

to produce this:

graph { vidiot -- v4; resolume -- splitter -- v4; v4 -- avemod -- ave5 -- v4; }

maybe break them up into a couple different instances within the same post for smaller sections

Yeah. I think I need to reorganize a bit the logic structure, as I didn’t have any “video mixer” item…rather an item for each video mixer channel, which isn’t working well here (but I still want to track the channels we use)

so rather than

vidiot > V8 channel 1

I’m trying with

vidiot > channel 1 > V8

you could label the connections (the “patch cables”) for channel numbers potentially too with something like

mixer -> monitor [label="#2"];

oh yeah! the changes you made above are making things much more readable
