Whirling Dervish

 Here are a few samples of OBS processing of found footage of a dervish fire dance.

Phosphortron 4

A related post - here is the same 'ghost bark' footage (from previous post below) processed thru Touch Designer using a custom-built network I've named "Phosportron4" - after a MAX-based standalone app ("Phosphortron") build a few years ago by Eric Souther & Laura McGough. Like Eric, I tried to emulate the main visuals relating to old green phosphor CRTs - "blur" (decay), "burn-in", and "edge detection." Also, included the ability to mix between source footage and phosphor-induced footage.

What To Do With Reaction Diffusion?

 After those examples posted previously (below), you might ask just how would I incorporate reaction diffusion into my video work? Here is an example compositing with my 'ghost bark' footage.

Punting the River Styx in Cambridge, UK - Wobbulator, Feedback and OBS FX - Part 2

Continuation of previous post: using OBS, overlayed (source) footage with Wobbulated version of same, including feedback camera processing and additional layers of pre-recorded material. Also, layered in processed footage from a custom video circuit developed during Sean Hollowell's Intro to Video Circuits class (at Polyphase Portal). 

Here are some more samples of resulting processed footage:

Punting the River Styx in Cambridge, UK - Wobbulator, Feedback and OBS FX

I finally got the kinks worked out of my system configuration and now can overlay recorded (source) footage with Wobbulated version of same (sometimes luma keyed), layer in other pre-recorded material (flames, fog), and also include feedback camera processing. 

Here are some samples of resulting processed footage:

Fire and Water - Wobbulator and OBS

As part of my ongoing process of OBS discovery and use, I recently was able to configure my system flow to support both my Wobbulator rescan feed AND the original feed being sourced to the Wobbulator. There is a slight delay of a frame or two perhaps, but most importantly this allows synchronized key overly effects to be recorded. 

As a note, I've found the Camo Studio app (for Mac) to be extremely useful in processing the video feed from my rescan camera (a Hi8 camcorder). It allows full control over frame resolution and frame rate, signal parameters such as luma, gamma, saturation, sharpness, as well as adjustment of zoom and relative placement/offset of the raster image. This latter function makes it easy to align the camera rescan manually - to center it and zoom to eliminate the CRT borders as desired.

So for your enjoyment below are a few samples of my "go to" rowing video clip showing various FXs and overlays.

Audio Reactive Spirit Howl

Here are some examples of using and audio reactive OBS scale-to-sound plugin for processing of the footage of Sylvain and Ghyslaine Staëlens's spirit sculptures that I had originally recorded at the 2022 Outsider Art fair. (Note other processing samples these posted previously.) 

Spirit Bark / Spirit Howl Redux

Here are some examples of OBS processing of the footage of Sylvain and Ghyslaine Staëlens's spirit sculptures that I  recorded at the 2022 Outsider Art fair. (Note other processing samples these posted previously.) Several of these examples show great feedback depth due to luma keying out the white gallery walls.

OBS processing - Part 7 - Celestial Dancer.

 Some nice samples of OBS processing of a Celestial Dancer.

Feedback Processing in OBS - Part 6 - Golden Butoh Dancer

Final examples of video FX processing found footage of Golden Butoh (Daidogei) Dance Troupe from Japan. The samples are all based upon feedback processing and reaction diffusion rescan effects within OBS.

Demons or tormented souls for possible inclusion in River Styx video program. 

Feedback Processing in OBS - Part 5 - Audio Reactive - Golden Butoh Dancer

Now something a bit different - audio reactive processing examples of video FX processing found footage of Golden Butoh (Daidogei) Dance Troupe from Japan. The samples are all based upon feedback processing and several available plugins (Move Transition, Scale to Sound) within OBS.

Demons and/or Celestial Dancer for possible inclusion in River Styx video program.  Or just plain fun?

Feedback Processing in OBS - Part 4 - Golden Butoh Dancer

Now some more examples of video FX processing found footage of Golden Butoh (Daidogei) Dance Troupe from Japan. The samples are all based upon feedback processing within OBS.

Feedback Processing in OBS - Part 3

As mentioned in the previous post, as part of the class "homework" assignment, Andrei Jay tasked participants to focus on generation of reaction diffusion field patterns in OBS feedback processing. In these experiments, a video of lightning is used to help "trigger" the diffusion patterns.

Feedback Processing in OBS - Part 2

As part of the class "homework" assignment, Andrei Jay tasked participants to focus on generation of reaction diffusion field patterns in OBS feedback processing. (Such diffusion patterns are a common element of Andrei's own work, as well as his hardware devices such as the RPi-based Waaave Pool and the new HD-based Gravity Waaaves. [You can find to more about his image processing products here.]

To get these reaction diffusion effects, it's important that the feedback camera be zoomed into the source frame pretty deeply (unlike the feedback shown in the previous post of rowing on the lake - where the camera was not zoomed in at all). Also, constant fine readjusting of various color correction filters such as gamma, saturation, brightness, and contrast is required to trigger and maintain the diffusion feedback generation.

Feedback Processing in OBS

I recently started a class in video art techniques using OBS - being taught by Andrei Jay thru polyphaseportal.xyz. The first class covered basic feedback techniques, filters, and whatnot. So I wanted to play around with processing based upon an input video clip - in this case my favorite River Styx 'standby' snippet of rowing on the lake. 

The format (framing layout) is based upon my desire to keep some of the original source "seed" visible (on the left 1/3 of the screen), allowing the feedback slices to trail off to the right. Here are a few samples of the results:
