    J [SOLVED] NDI Multiple Outputs

    Hey everyone — I'm back to the 3x3 video wall and trying to see if it's possible to get all of the outputs sent from my two networked macs:

    Mac Studio M2 Max, 2023, 64GB Sonoma 14.6
    Macbook Pro M1 Max 2021, 64GB Sonoma 14

    I'm sending 4 stages (1920x1080) from the MacStudio to the Macbook Pro via NDI. The Macbook pro has a display link tripple tap from pluggable, plus I'm outputting via hdmi adaptor one of the thunderbolts. Frame rate, load — all look great. When I look at the incoming NDI signals on NDI Video Monitor, they look great. But when I output stage on izzy it does nothing but stutter. 

    Scratching my head here and haven't found any recent threads on this. Any thoughts?

    mark_m UVC to NDI adapter

    Just stumbled across this UVC to NDI adapter.
    https://www.obsbot.com/store/p...

    It takes the output from any UVC webcam and turns it into an NDI signal over ethernet.
    Could be very useful in situations where you need a long cable run (@Eva ) or where you want to get additional live video inputs into Isadora on top of the four that Isadora's live capture supports. They don't say what the max length of ethernet cable would be, but I've asked.

    I've a couple of Obsbot products and in my experience they work well. Not bought this yet, but it's on my wish list.

    Fred NDI and resource use.

    I was working with some large NDI screens and it felt like they were not running at the full framerate. My resource monitor in Isadora showed a healthy frame rate, but the refreshes and manipulation I was doing did not seem to be up to speed.

    Is NDI resource use calculated in the resource monitor? Is the NDI data handed off in another thread? Is there a simple way to get the NDI frame fill rate?

    Fred [LOGGED] Resource use - stopping and starting NDI output - and feature request - an NDI output actor

    I need to use Isadora to convert some blackmagic video inputs to NDI. It will be for an installation that will run for a month. The conversion only needs to happen sometimes, so I want to stop it and start it and this should be automated. I dont want to run the capture and NDI output for so much of the time when it is unused.

    It is a simple task - just start the capture and output to virtual stages. But how can I stop the whole process and only start it when I need it - I know I can stop and start capture but what about the NDI conversion - this is a CPU heavy process that I dont want on all the time. An NDI output actor would be great - but in lieu of that how can I stop the processing - even when I am in a scene with nothing in it I still see the NDI streams on the network. Is there a way to stop the processing. 

    At worst I will make an apple script to open and close the whole patch if I need to but this feels like taking a sledge hammer to a knife fight.

    N [ANSWERED] How to download NDI Watcher and Screen Capture Actor

    Hello,

    I was wondering if I can download the NDI Watcher and Screen Capture actor in the Isadora Demo Version 3.2.6 (Intel).

    I am using a MacOS Sonoma 14.4.1

    I have included the screenshot of what Isadora said when I downloaded and tried to open the Screen Capture actor.

    I'd like to test how I can bring live footage from a phone into Isadora to projection map the live feed.

    Thanks!

    R [ANSWERED] TouchDesigner to Isadora - multiple NDI outs?

    Hi all - working on a show that's using TouchDesigner piped through Isadora to project some particle systems and audio-reactive stuff. We've got TouchDesigner on a PC, and Isadora on a Mac, connected over Ethernet and sending/receiving NDI signals. Isadora's NDI watcher sees the NDI input from TouchDesigner, but my designer has multiple NDI outputs he'd like to send, and Isadora currently is only able to see one/whatever was last opened. He basically wants to cue through the different outputs in TouchDesigner, with each Izzy cue pulling from a different output. I will admit to not being as experienced with TouchDesigner, so I was wondering if there were something I could do on the Isadora end of things to make that possible - or if it's some programming that needs to happen within TD. Any advice would be much appreciated!

    erikherz [LOGGED] NDI output with audio

    Is there a way to send NDI with audio? I selected NDI in the Stage Setup and I see NDI video on another PC with NDI Studio Monitor but I do not hear audio on that PC from the NDI source.

    jfg [LOGGED] NDI Audio output

    I'm a little confused about NDI. Am I correct in assuming that Isadora receives sound from an NDI source with sound but does not send sound even when NDI is enabled in Stage Setup?

    If so, I would like to see it.

    The second topic is more for bugs but I can choose only one category .

    If you have FCPX installed you get automatically NDI Audio installed (you can also download it from https://ndi.video/), which allows many software to send the audio via NDI if you select NDI audio as output in this software. I tried to select NDI audio in the Movie Player, after activating Audio Device, but then the player stops immediately and only runs again when I select another device.

     In a word, I have not found a way to send video and audio via NDI from Isadora to another instance of Isadora on another machine and I wish I could.

    best regards

    R NDI 5 Watcher not showing image

    Hi all!

    Working on a show where the designer would like to NDI into Isadora for mapping and masking in AE and Premiere. The last show we worked on together in October of 2022, we did this, and it worked perfectly. For some reason it is now not working anymore. The show computer we're running Izzy off of is a Mac trashcan (2013), running Big Sur 11.4. Isadora is v3.2.5. The designer is working off of a MacBook Pro hardwired into the show computer, so no wi fi issues. The NDI Watcher actor can see the source - like it's listed there in the source list and you can select it - but there's just no image. The NDI video monitor (as part of the NDI tool kit) does the same thing - I can see the source and select it, but it's just a black rectangle. The same happens with my computer as well (also a MacBook Pro). We've tried rebooting everything, redownloading NDI, redownloading the NDI watcher actor, and using older versions of Aftereffects. I can also confirm that the "NDI output" checkbox in the preferences for both Premiere and AE is selected. Anyone run into this or have any advice?

    Abel [ANSWERED] Sending NDI from TouchDesigner to Isadora

    Hi,

    I was wondering if someone could help me out with best practices for receiving NDI.
    I'm getting a feed through from another computer running touchdesigner
    we're connected through the same LAN on which no other computers are present and which is not connected to the internet. |
    I do manage to get imagery through to my system however it seems to just be at 5 - 8 FPS

    I'm getting a very laggy feed through my ndi watcher, I've tried adjusting some parameters, like the framerate of Isadora or the general service tasks.
    The bandwidth from the ndi actor. but I never seem to get rid of the stutter. Also on their end I've tried to adjust the frame rate, etc. Is there anything I'm forgetting to check or adjust? 

    Or could it be that my system is just old or incompatible with their newer MacBook?


    my system:
    Windows 10
    intel i7-8750H
    32 GB RAM
    Nvidia GTX 1060

    Their system:
    Apple Macbook pro M1
    OS: Ventura 13.0

    would be amazing if someone could share some of their best practices :)
