Hi all

I made a load of Isadora video resources last year (no, wait, 2020! 😨) when I was teaching at Emily Carr via Zoom, that I'd like to belatedly share.

There may be better ways to do some of these things now, and other topics are covered by the Troikatronix Youtube channel, but hopefully you'll enjoy the brevity and style of these videos anyway (especially the Kate Bush episode !)

I'm teaching Izzy again now, at Concordia, and hoping to develop more resources - I also have a load of patches / activities that I need to dust down and share.

Anyway, have fun! Feel free to use and share in your own lessons - feedback most welcome!

Sam

@bonemap Cheers Russell - I think Loopback and live capture could be a good workaround for now 👍

 How is that? Does the '.' not display for your when 'Show Value of Linked Properties' is selected?

 Yes, this reminded me that I'd seen this before. I searched the database for a report but there wasn't one, so I logged it as a new entry.

@woland Brilliant! Thanks so much. I had assumed that apps opened Rosetta when required but I now understand that for everything APART from the plugins required to use a depth camera, Izzy works in native mode - which is great.

Cheers, David

@kikko

Do you have access to any video extenders like Matrox Triple Head 2 Go? I would be interested in knowing if connecting both projectors through such a device stops the issue of a display being lost.

Hi,

This demonstration patch might be of some interest for your project. It constructs and maintains a rectangular surface of particles using an external coordinate source (txt file) and Data Array so that the repel and attract properties of the 3D Model Particles actor can deform the surface. A keyboard trigger then rebuilds the rectangular surface so the effect can be repeated. It is capable of taking a video input.

demo-particles-03.zip

You can also look at the 3D Mosaic actor it will allow you to create wave like deformation on a video grid surface constrained to a rectangular shape.

Best Wishes

@dusx Hi dustx, this is all a bit strange, I've cleaned my drive but am still getting the same issue with the Screen Capture on my system. here's a grab to show you the windows available. As I say there are many more windows open which don't get detected...

 Thanks Lucas. My question was about El Capitan

I personally updated one of the two trashcans from El Capitan to Mojave. There are instructions in this article in the section "How to install an update to macOS in High Sierra or earlier" on how to update that generation of macOS to a newer version.

Also, though El Capitan is not officially within our list of supported operating systems, Isadora 3.1.1 might work fine on it. My laptop was running Isadora 3.0.8f12 on El Capitan without any problems. Testing is key though. Ask them to boot up the machine and hop on a zoom call with you so that you can remote access the machine through zoom in order to install Isadora 3.1.1 and make sure everything works alright.

@jtoenjes

Open Task Manager and see if Isadora.exe is still up. If it's there, end the task and you'll be able to re-launch Isadora.

@merni

Hi there Merni!

Thank you so much for getting back to us / letting us know that everything worked out for you.
And no, the team is working hard on the next release. When the feature is done we will release it to our beta testers, your interest has been noted :)

Thanks again.

@talyarden

Hi there Taly!

So for formatting strings we can use the actor "Text Formatter". Double click on the actor and a little window will open, in that window we can use the P (for parameter) followed by an index starting from 1 to say what parameter we wish to use.

So let's say we have the text

"command=hello world"

and we wish to change the text after the = to do so we use the following.

"command=" P1

If we now press OK, mutate the input of the param 1 to text (simply connect an trigger text to it) we now see that when we change the Trigger Text input / trigger it that the output of the Text Formatter changes.

@jandraka

As long as you look at what the slider says, that will always be accurate, because any change you make on the slider immediately takes effect on the actor (even if the input on the actor doesn't update visually to tell you that). If the slider for a Movie Player actor's "Loop Enable" input says "on", then "Loop Enable" is "on", even if the actual input on the actor has not updated visually yet and still says "off": https://recordit.co/WBFctO5IUA (You can also see that the input on the actor updates visually once you close the slider.)

As you said you can also type into the field and press enter, or click on the field and hold down the mouse button to drag up and down through the various settings: https://recordit.co/0EAekYF41O

@CitizenJoe @DusX @Woland 

These are some great ideas. I really like that suggestion from @CitizenJoe of making a video overlay. I can just make a video of a white wall being lit up by a flickering flame and overlay that on the video. That seems like the simplest (if I can make a decent film) and probably uses the least cpu/gpu.of making a video overlay.

Thanks for the suggestion, I'll give that a try.

@woland thanks so much - all sorted! Best, David

@tlaloc

We are working hard to improve our audio system and live capture in Isadora.
Please submit your features requests via the Support link in my signature.
We evaluate each and every feature request we receive and have improved our planning process many fold over the past few years, I am very excited about the next versions of Isadora.

@tlaloc

There is no problem panning your inputs using the AU Matrix Mixer. However, you will not be able to achieve frequency analysis on 8 channels of audio as you can see the inputs are currently limited to 4 and audio analysis is done as a mono track (I believe it is the first channel of a multi-channel track). There is currently no way to select the channel to be analysed from a multi-channel audio track.

Best Wishes

Russell

If I send direct (without Router) to Blackhole or Built-in Output there is no problem

 I have confirmed with Mark that this router is not designed for the 'audio' data type. It is a bug that the router accepts this data type connection.

x64 version of Windows

 Yes, a 64bit version of Windows is required. 

@woland I would love to try that too!  I have a Panasonic AW-HE40 with NDI that I am trying to control via Isadora patch

this is a cheeky question, but I am going to ask it anyway:

Is there any chance we can have some hints about future developments with how Izzy works with sound?

I am wondering whether to buy some 3rd-party soft and hardware, and it would be good to know if there things in the pipeline that might mean that I can save my money, or spend it differently.

Sorry... I know this is annoying, but I imagine there may be others like me.
