hi,

I was initially drawn to the real-time video effects that were possible with a live camera and a dancer on a stage. My interest was in the quality of projecting ethereal wisps of light generated by the dancers own patterns of body and limb movements. Without the benefit of an instructor or Isadora mentor early in this development my first patch was a reflection on the ephemeral ghost in the machine. Finding the combination of Difference and Blur in those early dabblings was a revelation! Circa 2002. Of course, at that time, the latency through the system was much greater even at low resolutions and the Blur actor was a frame rate killer. I think the effect had been demonstrated by @mark in an early online video and was an Isadora staple effect that gave the quality of a bloom or glow of light generated through live capture.

best wishes

I'll do it eventually, I promise!

No that is because Isadora JavaScript actor has some gotcha's, the final input needs to be triggered for the code to run. Since I use Pressed / Released triggers this had to built in for the sole purpose of forcing Isadora to run the code and give me the correct values. If you remove that you won't get proper triggers :)

@martin_kemner

Thank you for your kind words. After such an intense time getting Isadora 3 out there, they are much appreciated by myself and everyone on the team.

Enjoy. ;-)

Best Wishes,

Well in the forum showcase is the right place for that. But your patch just needs a bit tiding up and maybe an interface to post it in the plugins page.
And to reset you can add a "user actor on/off" (copy it out of a user actor) and that way you can reset your patch.

Together with the visual artists Marcela Rapallo and Rafael Arévalo Peñuela we were testing the possibilities of staging with Isadora software and the new configuration effects on the stroke: sustein and evanescences -fade outs- in real time, using a MIDI controller as an interface physics between the graphics tablet and Isadora.
The new plug in "Live Drawing" created by @mark  provides a thorough control over the most important parameters in relation to live interactive digital drawing, opening a new field in visual experimentation.

WOW - thanks so much. I needed this kind of brilliant thinking several years ago for an installation... I came up with an ugly kluge - so pleases you shared this!

This is a mapping project that we did a few years ago in Orlando.  Permanent installation. 4 projectors in a 2x2 grid, shooting from a hotel room (beamers are built into a corner sofa 😆) and an office space. All the mapping is in izzy map so we can just feed it unwarped 4k content. Izzy sends MSC commands to a controller to trigger moving lights and colors in sync with video.  Turns on and off on its own every night and randomly selects from 30 different pieces of content.

@bonemap: Got it. Will be tinkering with it this week. We are having snow here for Easter Sunday!

@mark

Belated thanks for this session, and thanks so much for answering my questions. Really appreciated. Look forward to seeing you again when the Guru sessions resume!

I got a 404 Error when I tried to download the updated GURU #8 patch this is the link that is listed under the Guru #8 video that doesn't work

 It's uploaded now. Please try the same URL again...

Thanks to Jan van Hapert for the new "guru" backdrop!

Here is my first video made with Isodora 3, CamTasia Studio 9 and Adobe Premiere Pro 2020 CC.

I used my Nokia 4.2 Android phone and its Web-cam software named DroidCam.

Please do, why would we need two plugins that do exactly the same ? DusX and I both have different ways to approach it, and perhaps some might agree more with my style then the original plugin but I dont see that as a valid argument to have two plugins that do exactly the same on the Plugins section.

 I think it's fine to have two things that are a different approach to the same task, that's one of the beauties of Isadora after all!

the Built It series on YouTube should help you get a sense of how you might accomplish similar effects and more.

It's a new series.. but I'm adding to it weekly

@Woland @mark thanks for the feedback and I know you guys are doing the best you can with a changing hardware and software environment. The frozen in time method is exactly why I'm on a 2012 mac pro maxed to the gills.. but yeah i absolutely would like to find new more efficent ways to recreate my patches.. the concepts are not that difficult I dont think. I'm a musician and audio engineer by day so video software/plugin coding isn't gonna be my wheelhouse. I would like to hire someone to help me.. I think it could probably all be done with GLSL shaders, and some simple 3D models.. I posed an add about a year ago here on the forum to hire someone but no one was interested at the time. I guess I'll try again. If anyone is interested please let me know. thanks, D

Hi,

here's the user actor that did the 'Framing' or inserts of images in the first episode. It's got a bit more functionality than we needed, with room for 4 main inputs (in our case the cameras from each actor) which can each be scaled and positioned. Then there's an optional background layer which could obviously be anything but we often set it to a semi-transparent colour like in the screen-grab below. Finally you input a max horiz/vert size to get the shape right and set a size and colour for the outline, if you don't set these then you don't get an image. The on/off for the freeze function grabs a still and desaturates it when set to 'on'. The on/off for the gate works a bit like a bypass, this has to be 'on' to see any output.

Oh, and it's called 'No FX' because originally we made it with an option to turn the various effects on and off within the actor. We took this out because it always seemed more efficient to do this upstream of the framing, especially where we had several 'frames' within a scene and that way we only needed apply the effects once as they were always the same. So, it wasn't a deliberate punk reference, sadly.

@django Nice work! Thanks for sharing your process.
