Guru Session #10: Isadora for Remote Performance (April 24nd, 2020 - 6pm CEST/5PM GMT/12pm EDT/9am PDT)



  • Dear Community,

    For this special "guru session" Isadora's creator Mark Coniglio will show you the potential of using Isadora as a tool to facilitate remote performance, a topic that is high on everyone's minds right now. We'll cover Isadora's new Screen Capture actor which allows any portion of your screen to serve as a video input, leveraging Isadora's NDI® implementation to live mix multiple video streams from Skype, how to send Isadora's stage to YouTube or Twitch using the freen open source brodcasting software OBS, and more. Basically, we're going to go over everything we can think of that will empower you to create online shows in the time of social distancing.

    6pm CEST (Europe)
    5pm GMT (UK)
    12pm EDT (East Coast USA)
    9am PDT (West Coast USA)

    We'll post the class materials and live stream link here at 5:50pm CEST on April 24th.

    We look forward to seeing you there!

    Best Wishes,
    Mark

  • The video replay of the live feed is currently unavailable. I need to blur out one piece of private information that was recorded. It will be available later tonight or first thing tomorrow.

    Thanks for your patience.

    Best Wishes,
    Mark



  • @mark

    The video is back up for viewing!

    Enjoy,
    Mark



  • Hi Mark,
    This is exactly what I wanted to learn during this quarantine. I wanted to live stream my band with video projection. 
    I think I have everything set up, but for some reason OBS is not detecting sound or video from Isadora. Do I have to upgrade to Isadora 3 in order to do this?
    Thanks,

    Nao

    Do you have the Syphon output turned on in Isadora's Stage Setup Window?

    As for audio, which platform are you using? Mac or Win?

    Best Wishes,
    Mark



  • Thanks Mark,
    I am running Isadora 2.6.1 on Mac OS 10.14.6. When I go to Stage Setup window, I do not see Syphon option to click on. Am I missing a plug in or something?

    @Whatnao 

    This is an Isadora 3 feature. You wont see the option in 2.6.1, for only 170 euro you can upgrade to version 3 from Isadora 2, or you can rent a weekly license at the online store. https://sites.fastspring.com/t...
     (10 EURO for a week) if you wish to play with the new features.



  • @juriaan That's what I suspected. Thank you for the info.



  • I'm doing this independently after the fact and using Firefox as my browser. It doesn't seem to want to allow me to have multiple windows open at a time. The window list also shows nothing. Mark can you tell me what browser you were using? Other than that it is successfully showing the tutorial on YouTube-So the plug in is working. My Plugin says Alpha. Hope that's the correct version. Thanks for all you do. Trying to gear up to help PICA here in Portland with their gynormous festival in september.



  • @nandada Figured out the multiple windows. #oldperson   



  • @mark Hi mark, Thanks for this info. I am very successfully collaborating with dancers using Skype input with the NDI plug in. Now id like to broadcast the live feed experiments we are doing. I have an offer to perform the live feed on zoom. Anyone have suggestions on how to share the screen and broadcast to Instagram live, Facebook live, or Zoom? Much appreciate hearing about successes broadcasting live feed from Izzy. Thanks gwen

    Zoom has no input via NDI or Syphon -- the two ways you can send a video signal from Isadora into another program.

    But, can't you just share your screen to Zoom? Isn't that the simplest thing to do?

    Assuming you can't do that for some reason, I would suggest OBS (Open Broadcasting Software) because it has a Syphon input, which is very low impact performance wise and very low latency. Once the image is getting into OBS (as I discussed in the guru session) then:

    1) Use a "Virtual Webcam" to get the output of OBS into Zoom: On Windows, there is a plugin that can output OBS as a virtual webcam, and take that into Zoom. On macOS this requires a software called CamTwist or ManyCam, both of which are paid programs. (I tried ManyCam as a proof of concept of this the other day, and it worked as a virtual web cam.)

    2) To broadcast to Instagram, you can apparently use OBS in combination with something called YellowDuck to get broadcast a live feed.

    3) I believe you can broadcast to Facebook live from OBS directly.

    4) For sure you can broadcast OBS directly to YouTube and Twitch.

    Those are the options I know about. There may be more. However, I've only ever done broadcasting to YouTube myself. I have no experience actually doing the ideas offered in points 1 through 3.

    Hopefully that's enough to get you going.

    Best Wishes,
    Mark

    Just a note, for security (and to annoy the rest of us) zoom does not support virtual cameras as input anymore so option 1 of @mark 's response is no longer working. You can use zoom's share screen function though.

    Thanks for this information Fred. Is it true on both MacOS and Windows? Or just MacOS?

    @gwen-charles and all

    I've just posted a knowledge base article on sharing Isadora's output via Zoom. But whether it was Isadora or QuickTime player, the result on the remote computer was pretty bad: I was seeing maybe 3fps even though Isadora/QuickTime Player were rendering smoothly on the host computer.

    Best Wishes,
    Mark



  • @mark Thanks Mark. I tried the simplest version " Share screen" on Zoom and it was a success! thanks! I will try the other options next to try to get onto Instagram Live and Facebook Live. gwen

     Do you know if previous versions Of Zoom that allow virtual cameras are available for download?

    Kind Regards

  • @bonemap not from zoom but you might be able to find them. It's not really a good option as it may give connection problems and incompatibility for other users. I have seen older versions give trouble with the shared stereo audio setting for groups.

    @mark as far as I know this is Mac and PC.

    The good news is they have reinstated access to Blackmagic drivers and other non-usb webcam video input. You can put your Isadora stage on an HDMI output that goes directly to a capture device on the same machine. This is a very neat and reliable solution with great quality.




  • Hi there Mark!


    I'm trying to run a live performance from Zoom through Isadora and stream it to youtube (all on my tiny little macbook air, she's taking the processing like a champ) and I have been able to get the video working successfully via the screen capture plug in for Isadora, but am having trouble getting the audio working.  I've managed to get the Isadora feed and the Zoom audio playing into OBS, but I'm worried that since the audio isn't playing through Isadora as well the video is going to appear laggy. I'm really stuck, what would you recommend I do?  Do you think running it through Isadora isn't going to cause enough latency to be noticeable and I should just leave it as is, or work on getting the audio into and out of Isadora before connecting it to OBS?

    Thank you so much!  I appreciate whatever feedback you can give me!

    @zaira_001 You don't have to pipe the audio through Isadora, but the Advanced Audio Settings in OBS allow you to manually create a delay in the audio and video to help sync them. Anywhere from 30ms to 300ms adjustment my be needed, finding the right numbers is a matter of trial and error. The Audio Output Capture from OBS will pick up any system-level audio (make sure you're using headphones to prevent a feedback loop if you're also using a microphone.)

    Audio is one of the trickiest elements to get right with live streaming. Test, test, test your setup and adjust the settings. A good metric to use is to "Record" from OBS instead of streaming, and then re-watch your recordings to determine how it turned out.
