hi, ok I understand better. The treadmill thing is more tricky because this means that the torso z plane won't move. But there might be another way.

One more body movement analysis thing that might help is that while a step is done there is a so called transference o weight. This means that that the center of the two hips moves on the x plane roughly above the foot that is pushing WHILE the other foot is on the air.

Other way is to se that the foot on the air is moving on the z plane in a negative value (goes closer to the camera) while the foot that pushes move in a positive value (in a direction far from the camera. In this case, in pseudo code this would mean

Check for the foot Z AND Y positions : look for the direction inversion of each foot and trigger the sound when a foot z values start to invert. 

Beware that the 30 fps of the camera will introduce a little delay between the calculation of the inversion and the sound triggering.  

I hope I am clear.

All the best

@ppp586 I'm sorry. I can't read chinese....

First It would be helpful to know about your Isadora system. This forum post will guide you through adding a signature to your profile which includes your system specs.
https://community.troikatronix...

Regarding latency, Each piece of hardware introduces at least 1 frame of latency. So best case scenario your Camera and Capture card will have 2 frames of delay. Isadora uses the OS media frameworks to interface capture cards on Mac and Windows, as well as, offers Black Magic Designs drivers for interfacing with Black Magic Designs devices. Black Magic devices may be the lowest latency option for Isadora at this time.

Elgato 4k capture likely runs some form of compression on the video (I have a 4k USB dongle version) and seems to have more than 1 frame of delay although I haven't tested with timecode overlays to get an exact count.

Any additional video adjustment/processing done by the camera or capture device will likely add additional frames of delay. So if your camera is natively 1080p but you are capturing at 4k, something in the chain is scaling the video, and possibly adding more delay.

@thatmattrogers said:

2: how many different NDI feeds can I run on the same network into Isadora without any trouble?

This depends on your network and the computer on which you are running Isadora. 

We don't limit how many NDI feeds you can bring into Isadora, it's just a question of at what point all that video is too much for your computer.

Hi this Mark!

+ thanks for this! PC illiterati that I am. I have only briefly looked into NUC's as potentially a 3rd smaller scale unit for specific networked functions, so I am interested to see it scales up well, I will check that spec out. Thanks. 

Also good to know re Windows. Kinda figures, but always worrying given the built in obscelescence of them all. 

Cheers

@alice

OK, please open a support ticket. We will need to take a closer look at what types of media/codecs you are using.

The Support Link is in my forum signature below.

@eva

I think you are just finding the edges of the Kinect OpenNI interface. It can be very picky about initiating. You need to activate things in the correct order. If it does crash, you will be best served to power off all parts and start them up again in sequence. I suspect that if you are careful about doing this you will find it becomes more reliable.

Isadora 3.1.1 may include some fixes that help you, but nothing I can think of that is specific to OpenNI.
You can install 3.1.1 and keep your current installed version. (yes the download link is now the latest version).
This article will help you install a second copy of Isadora (useful for testing): https://support.troikatronix.c...
NOTE: the file format will be updated for Isadora 3.1.1 so if testing a current project file PLEASE save as a new file (dialogs will warn you) so that you have a safe backup

@jivrodriguez Could you get everyone to join a Zoom call with their personal devices and then use the free version of ZoomOSC to get a copy of the zoom chat room into isadora via OSC?

@jtoenjes

You can do either.

If you only want the newer version, simply install into the same program folder (the default is great). If you want multiple versions, installed, give each its own uniquely named program folder.

Thanks @jfg, i added a control button to the trigger and a short trigger delay before the take snapshot and this works well, so long as i remember to take snapshots using the button and not the camera icon

@trevorn1

We're glad to hear that you've been enjoying using Isadora.

when I close Isadora it says I've crashed

Can you send a screenshot of the crash dialog? It's important to know whether it crashes and gives you the option to send us the crash report through Bugsplat or whether it crashes and only gives you the option to send a report to Apple.Does it crash even if you open a blank file, then quit? If not, it may be something specific to your file.Could you please add your hardware setup to your signature line? It's hard to diagnose issues when we don't know the hardware setup or the OS involved.

anyone has any pointers for installing plugins as well I'd greatly appreciate it. I got the shaders in but no luck with the Actors

When you download one of our official Isadora Actors from the TroikaTronix Add-Ons Page, the download will have a read-me file as well as a folder for Mac and a folder for Windows.

Windows Install:

Mac Install:

If you're talking about User Actors from the TroikaTronix Add-Ons page, the process is a little bit different, but I could walk you through that if that's what you meant.

@dusx thank you so much! this is very helpful.

@Ubik 

Sorry to disappoint, but we do not have seasonal sales.

Best wishes,

L Wilson-Spiro

Ok, thank you:) Then I will look for an extra external live camera... And use my older Kinect.

@eamon

oh, and the codec should be something like AppleProRes or HAP. h264 does not work so well with speed changes.

Best Michel

Thank you both! 

@Juriaan: This worked perfectly--thank you! I can go back to clumsily dancing this little dude around. 

@bonemap: Ah! That makes a lot of sense to me now. I'll work through your example skeleton patch and keep trucking along.

@fred

Both of these issues can be corrected by setting/mutating the types as needed.

In the case of the Listener, its as simple as setting the type input to 'text'. That will allow the full ip text to pass through.

For the Global value, you need to mutate the input (as you have by connecting it to a text output) AND mutate the Get Global Values output to text in the same way.
If you connect this output to the text input of a Trigger Text actor, it will mutate to text, and you will see the full IP address.

@soniccanvas

Please read the post I made today about this.

In a recent forum post, a user pointed out that Isadora 3.1.1 and Isadora 3.0.8f12 were not compatible with USB-C Hubs that rely on DisplayLink drivers. I wanted to address this briefly.

SHORT VERSION: Yes, it is true that many hubs that rely on DisplayLink drivers are incompatible with Isadora, though there is perhaps one exception. (See "EXCEPTION" below.)

LONG VERSION: It is clear that most USB-C Hubs that rely on DisplayLink drivers don't work with Isadora because the drivers do not allow you to create a valid OpenGL context, something that's required for high speed rendering. But, I wanted to find out more. So I went to the (excellent!) local Mac shop to purchase one of these hubs so I could try it. While the headline of the DisplayLink web page leads off with the headline"Truly Universal", a tech at the shop said that these devices caused so many problems for so many customers with so many apps, that they simply stopped selling them. They now actively tell their customers not to use devices that rely on DisplayLink at all.

EXCEPTION: @liminal_andy shared a post about a specific USB Hub from a company called Plugable that apparently does work very well with Isadora. Perhaps there are others. But I can say with some confidence that is Andy says it works well, then you can have some confidence it does in fact work well.

CONCLUSION:

So we're sharing their recommendation: we currently do not recommend these devices for use with Isadora. If you do find some that work well, then please reply here and share your experience with the community.

Best Wishes,
Mark

P.S. I want find a way to investigate this when I can make time for it. Even though the DisplayLink system will be inefficient compared to a for-real OpenGL enabled output, I want to see if there is at least a workaround that allows 1) Isadora to work with these devices, and 2) for us to warn the users the device will be low performance.

Assuming the 3D Rect Project is going to a Stage, use a Stage Preview Control.
