Yes. I played around in this example file with throwing the two images I want to blend into Virtual Stages first so that I can add the edge blend to each Virtual Stage with the Global Edge Blend Mask actor then use Get Stage Image actors to combine the feeds from the Virtual Stages and route the result to a normal Stage. The benefit of this is that when you pull the two images back in, you can then apply video effects to both of them together (I think). I'm sure there could be a way to improve on my method and I didn't bother to get my blend looking perfect, but this was just a quick sketch.

Splitting content in two, sending each portion to a separate Virtual Stage, and adding the appropriate edge blend to each Virtual Stage

Pulling in the feeds from both Virtual Stages and compositing them on a single Stage with physical displays assigned to it.

Thank you very much for this.

@woland

thanx for the tip!

This is pretty much what this company do: https://www.immersiveclassroom... 

The main issue is getting a machine that can run the video for a set up this size. 

Thanks for sharing @Woland 

Dear All,

So I was invited to a little birthday party/dance jam that took place on Zoom. Wanting to impress the group, I whipped up a little reactive patch that does some trippy effects on the live image, modulates those effects with the using the computer's built-in microphone, and then sends the output into Zoom. It seemed to have the desired effect because people were writing in the chat, "Whoa! What Zoom effect is that???", and I was saying "Well, it's not done in Zoom at all; it's done with Isadora." ;-)

I thought I'd share the patch and some instructions so any of you could do the same and also learn this technique of sending Isadora's output to Zoom.

The Isadora Patch

To start, open the example patch attached to the bottom of this post.

To make sure the patch will work, choose Input > Live Capture Settings and make sure you have a web cam selected under Video Input, and that you have a microphone selected under Sound Input. Then click Start Live Capture and make sure you can see the video thumbnail, and that the VU meters underneath it are moving.

In terms of how the patch works, it's pretty simple.

Using the Video Delay actor, I combine the live feed and the delayed feed using a Effect Mixer set to 'addovr'. I then use a Video Fader actor to dim the image a bit, and send that to the Stage with a projector.Then there is a Stage Background actor to do the feedback. As you can see, the 'fb scale h', 'fb scale v', and 'fb rotation' being modulated by some Wave Generators so they are constantly changing.Finally, the Sound Level Watcher actor modulates the 'fb intensity' input of the Stage Background actor. (You may need to reduce the value of the 'limit max' input of the Limit Scale Value actor if your music is soft; I was playing the music pretty load for the party.)

So that's the patch. But the key thing here is that the "Syphon" output is checked for the Stage in the Stage Setup editor. With my example patch open, choose Output > Stage Setup to see this setting.

That's how we'll get our video output to Zoom.

Get the Video Ready for Zoom using Syphon Virtual Webcam

Now, to get the signal to Zoom, you need our free tool Syphon Virtual Webcam, which you can download from our plugins page. Follow the instructions there and within the program to install it on your computer. Once it's installed, start it up and you should automatically see the feed from Isadora in the Syphon Virtual Webcam window.

Bring the Image Into Zoom Using the Zoom Preferences

Finally, start up Zoom. Once it's open, go to the Zoom Preferences, click on the Video tab, and choose OBS Virtual Camera for the live input.

 

That's it! You now have Isadora's stage as a the "camera" in Zoom.

Hopefully that's a complete enough description for you all to follow. Let me know if anything here doesn't work out for you.

Best Wishes,
Mark

@woland thanks, the blend maker did the trick

although that could be convenient to have the rotation parameter shown so as for the resolution when we move a point.

 Yes, I already added that as well. :)

This was a very interesting session, as usual !

I never made soft edge with 2 or more projectors, but I remember that the position and the distance between the 2 projectors has to be the more precise possible, even if Isadora let user to make changes through Izzymap and Stage Setup.
I found in my notes this drawing which explains how to calculate the best set up, if it's useful for someone.

Best wishes.

@crystalhorizon and @Woland Thank you very much !!

Best,

@armando No of course !! 

That question came up when Dusx explained about the stage layout and that made me doubt.
Returning to the original theme therefore the masking tool is still the Edge Blend Mask, right?
Many thanks
Best,

@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,

@fubbi

Sorry to dont back here in this question. I will check correct settings and give a feedback - this computer are in other local.
