I have a vidiot that Iā€™m currently trying to find a buyer for that is posted on the LZX facebook page! (nicholepichon)

between the two for starting out you get more bang for you buck with the vidiot but the cortex is fantastic when you are ready to start outputting via component

Here is the info about the yoga event we did:

Lay Your Body Down

PlySpace Gallery | Muncie, Indiana
Thursday, May 30, 2019

Daniel Chamberlin and Mark Perretta will join PlySpace Artist-in-Residence Karl Erickson for Lay Your Body Down: May 2019. This installment in the monthly Drone Yoga series combines Yin yoga and meditation with an immersive audio-visual experience including long-form keyboard and tape loop improvisations from Perretta and video projections from Erickson.

And some pictures:

I was using a vidiot and an 0-coast to do the visuals (not a batumi, I forgot!).

Video feedback makes it fun.

Wow, this is just incredible. Exactly what I was imagining wanting to do! Thank you so much for sharing. This definitely convinces me.

Thank you @robotboot! That makes complete sense. Vidiot it is :slight_smile:

These videos are so, so cool. I love the range of tones and textures! Makes me very excited to start!

:point_up_2: video feedback and camera feedback are great additions to making videos with a modest set up.

#20

Wow. Itā€™s incredible how much you get out of that! What cameras are you using? I suppose I could look for some thrift-store camcordersā€¦

Hey @Hovercraft - I feel like Iā€™m on a similar path. Did you manage to integrate the 3Trins with your LZX gear?

I have a 3TrinsRGB and an Oscillatorscope and a few other bits and pieces. Have been tossing up whether to dive deeper into LZX territory, even if just to build a compact mixer for the gear I already have but I wonder if just a V4 or even just some additional capture devices with a laptop (I use Lumen and VDMX a fair bit) would be sufficient.

I find it hard to understand whether LZX gear is plays well with gear from outside itā€™s ecosystem and Iā€™ve not had a chance to try out the LZX stuff anywhere to understand how it might fit into my workflow.

#22

The 3trins pairs well with the v4. If you are using lumen you can send video out from lumen via a conversion box into the 3trins, process, then out to the v4 for your final mixing and effects. You can build an expansion to send itā€™s signal into the lzx system or if you get a cortex or vidiot you can send that in a sync the system to that signal.

#23

one was a standard thrift store vhs I believe and one was a cannon t2i (could be any camera though)

the dual projector dual camera feedback setup is pretty magical without any LZX gear but throw in a feedback processor like vidiot and you can go wild

#24

Iā€™m experimenting with similar technique (2 projectors, 1 camera and a computer) and it looks lush. My aim is to work with different textures and movements of the artefacts: from big islands to small bird-eye like groups. There is not too much information available about the good resolution and connection to use. Any suggestions on this regard? I would guess the better resolution of high-end projectors (used for home cinema systems etc) will improve the fluidity of the artefacts and ā€˜feedback islandsā€™.

#25

I mean more resolution may not be bad but honestly I am just using what Iā€™ve got available I havenā€™t bought or sought out and projectors since way before I started with video synthesis

improving the feedback quality all comes down to your ambient light, camera settings (focusing, white balance etc.) and angle of camera to screen

if you throw in some flashlight/laser pointer or some source of light it can be be very fun to play with in this setup too

making sure to mess around with the orientation (flipping the image around via the OSD) of the projectors (I may have mentioned that earlier) if key to this technique

Thanks, thats helpful. Music will probably take most of my attention during the performance so video will have to live with lots of inconsistence and learning by doing.

#27

As someone that also works with feedback something to think about is the added delay that higher resolution devices add to the signal. I do most of my feedback with a old tub camera and a CRT monitor and while the resolution is SD some things it does are unobtainable with newer hirer resolution cameras do to the lag/delay time added but each digital thing in the system. thus is an example of some all analog feedback.


I am not saying this is better or anything like that and this was filmed with a HD camera that was not attached to the feedback line. I think its an example tho of more resolution doesnā€™t mean better feedback. Digital also has its own benifits of a longer delay between what is seen on the screen and then coming back to it. its own ascetic as well.

is it me or is the hd camera not focused correctly? Amazing patterns and colors

#29

I just started using Vidiot, but have been messing around with software ā€œanalogā€ video synth ideas via Lumen for a while, and more recently the JS / browser based Hydra. Hydra was where I really started to appreciate feedback.

Hereā€™s a short piece I stitched together Monday night from footage Iā€™d been accumulating for a few days. Iā€™d actually like to re-edit it to cut out the color bits, butā€¦all the black and white sections are purely feedback with a nikon powershot pointed at a flatscreen SD TV. You can even see the little battery indicator in the cornerā€¦no idea how to make that go away :slight_smile:

Part of generating patterns and gradients is having the camera in the feedback line be out of focus or have the focus moving. So yes this image is on the softer side but is also part of the ascetic. I chose a softer image over getting all the digital aliasing. Idealy I would have also recorded the tube camera and so on for comparison. Also YouTube is crushing this video I can see a drastic difference in quality between my originals and what gets postedā€¦tooo many colors and gradients over here.

Video compression and I are struggling to find a way to live together in peace. h.264 really kills the detail I see on the TV. For a while I was recording with a HD webcam pointed at the screen, which gave everything a kind of HD lowfi look. I bought a Black Magic Intensity Shuttle to go direct to the computer, which removes a bit of the lofi (not necessarily a good thing) but now Iā€™m struggling with codecs and compression. Iā€™ll figure it out, will just take some time.

Butā€¦yeahā€¦the things I see with my eyeballs on my TV are different than what ends up on Youtube for sure.

#32

Yeah I like to go into glitch land and the old Sony production displays will always show an image. Where as a capture card would loose sync and stop capturing or a project would loose sync and go to black. But itā€™s a huge pain to have to film the CRT and it normally goes. That looks great on the crt screen then less great from what the camera can capture and then YouTube just destroys it. It doesnt have the bandwidth for so many colors and fast actions. I still do some direct captures for the easy of it and not having much time but I do prefer the rescanning. Try and crunch the colors a little bit in the computer after capturing.

#33

thanks for tips, these are good to know and try. In my case itā€™s probably more convenient to play with the focus of the projectors. Also, I will keep my eyes open for tube camera+crt combos out there to try out the projector to crt display technique.
