Also, there's a professional AV community I'm part of called Office Hours Global, and I teach a free Isadora Lab (with no set curriculum) on Office Hours' 24/7 Zoom call every Thursday from 7pm to 8pm CET (so there will be one tonight). If you want to get your questions answered in person by me and play around with this concept in Isadora together you can register for the Zoom call here: https://zoom.us/w/96553474365?_x_zm_rtaid=BmS82XntQmSDwc5VH1xmhg.1707495640829.aa165f03228cff2c6df68f7116adcc28&_x_zm_rhtaid=189#success
I'll probably be working on this file in my lab tonight.
Best wishes,
Woland

we switch to Computer "B" from the Video Matrix (this would be a manual operation from the operator.)
Doesn't have to be manual if you can control the Video Matrix through OSC, MIDI, TCP/IP, Serial, using the GET/POST URL Text actor, or with the device's own API via Python code using the beta Pythoner plugin (just send in a ticket using the link in my signature if you'd like access).

I'm thinking OSC commands that send triggers from Computer A and receive the triggers on Computer B but that obviously means two different show files. I'm wondering if someone might have a better idea
I'm already working on an example file for you, but here's a basic explanation of what's coming:
Yes, OSC can be a way to go. You can also use Net Broadcaster actors and give each computer a separate Computer ID in Isadora > Preferences.../Settings... > Midi/Net > Net Setup > Computer ID.
If you want an automatic switch, you setup a "heartbeat", which is just:
- On the "Leader" computer: A background Scene you keep active Wave Generator into an OSC Transmit or Net Broadcaster actor
- On the "Follower" computer: An OSC Listener or Listener actor into a Trigger Delay actor into whatever it is that you want to trigger.
While the Wave Generator continues to function, it'll keep triggering the Trigger Delay actor and resetting its timer.
If the Wave Generator stops working (e.g. if Isadora crashes) then the timer on the Trigger Delay is allowed to run out and it triggers whatever is necessary to make the "Follower" become the new "Leader".
Now, you can make this as one file with a Selector that lets you tell the patch whether it's supposed to act as a leader or follower: Example: A Selector into the IP input of the OSC Transmit actor that lets you pick between the leader's IP or the Follower's IP and a Selector that closes a Gate to listen for communication from the "Leader" for the Leader computer and opens the Gate to listen for communication from the "Leader" on the Follower computer.
PANASONIC GH4 DSLR > ELGATO HD60 S > ISADORA. Has anybody been able to make this setup work using the GH4 for live capture, as my laptop will not recognize the the Elgato device? Elgato does not show up in Quicktime or any of the Elgato softwares. Any guidance and advice would be much appreciated. I'm using Izzy 3.2.6 in a Macbook Pro, 8 GHz Quad-Core Intel Core i7, Ventura 13.2.1.

Wow that is such a detailed a very complete answer / explanation !
There are almost always multiple ways to accomplish the same task in Isadora, so I like to give examples of different methods because some may be more or less well-suited for a particular use case.

I'd like to ask all of you about the math that is under the logo's movement in the 3d space.
I'm the one who made that video and I have no idea how the math works. It's Scene 22 in the Rokoko Studio Live Watcher tutorial on the TroikaTronix Add-Ons Page if you want to take a look at it though.
Isadora user needed in Melbourne Australia next week. Then Adelaide after that. Interested ?
Working with a Theatre company for a show assisting the lead designer who has been using Isadora for 10 years +.
Touring for the Adelaide International Arts festival premiere of Guuranda. Using a new Mac Studio M2 Ultra - with multiple 4K outputs.
If you haven't seen the new Isadora funny promo minivideo you should. Cool stuff team !!
But since we are in the kitchen here I'd like to ask all of you about the math that is under the logo's movement in the 3d space. How the Isadora logo can not only can shrink and expant in relationship to hand distance (that is relatively easy although I haven't tried yet) bit orient in 3d. It is mathematically challenging for me who's not good at math....
I'd love to try it with a video instead of a logo
Any clues?
It took me some time to learn how to work with the mobile app but once i got to know it i works great, especially the AI funcitons. I used it in a danse show to track a dancer. The app was the easiest to activate and deactivate the tracking.
Thanks so much to both of you! Helpful to see what direction to move in. I really appreciate it!
@woland Wow that is such a detailed a very complete answer / explanation ! Thank you for all of this if helps me immensely as well
