Hi All, I use a Grass Valley Video switcher and would like to control video clip playback with Isadora from a computer.

The Isadora side I'm very familiar with, it's the different protocal languages coming from the switcher that I'm trying to put together to send Isadora commands like Play, Stop Rew and more if I can.

My Current Choices: 

1, Contact closure, would work but it's so rudimentary and I would need to setup many triggers, but it's really easy.

2, RS-422, VTR/BVW, this has been around a long time and is probably what I'll settle on because I'm not a coder, but trying to learn.

3, AMP (Asynchronis Messaging Protocol) I'm most interested in this because it's IP base and makes a clean install, however as I said I'm not a coder and I'm having problems on where to start.

4, There are some other Protocols but most of them are proprietary.

Thoughts?

I'm starting my deep dive today.

make a User Actor from group selection in the Scene Editor

 Yes, I want this as well. It's on the list for sure.

The math inputs would also be nice, and is on the list as well. 

With that said, this made me think a bit about calculations, and with some AI help I whipped up this user actor, that will take a math formula, and a set of values via JSON that map in, and will calculate your formula in one go. dx-js-math-formula.iua4
Much easier than a bunch of math/calculator actors, and more convenient than creating custom JS scripts for every calculation
NOTE: you can right-click the user actor and open the HELP in the browser (its long)

Hi,

Wishing the Isadora community good spirits for the season! 

I have been working on updating the 3D object collision options in Isadora. Specifically to detect boundary collisions and object–object collisions in 3D space. The patch attached below is an offer to anyone interested in using 3D models and provides position and rotation outputs for the Isadora 3D Player actor: translate x,y,z and rotation x,y,z to simulate objects colliding, pushing and bouncing off each other and also bouncing off a boundary box aligned to 3d space. The actor provides inputs as follows:

- dt (recommended as a constant pulse input at 60hz)

- bounding box H,W,D (use in conjunction with a 3D Stage Orientation actor in the scene editor- move along the z axis to fit the stage)

- radius (the size of the collision detection relative to the size of the 3D object edge. This is based on a sphere.)

- bounciness of the object collisions

- initial speed of the objects when reset

- floaty to liveliness of the movement 

- reset (retrigger)

A limitation is that the actor assumes the 3D objects are all a similar size for collision detection.

the actor is easily modified for the number of 3d objects in the scene. Just one line in the code is changed relating to BODY-COUNT (the number of 3D objects in the patch). The corresponding outputs are then available by adjusting the number of outputs of the actor. (Each object has six outputs associated with translation and rotation)

here is 3DCollisionJS_2025 for Isadora 4, code assisted by copilot.

Best Wishes,

Russell

How are you values packed with the Matrix value receive?
The output of the actor is Text. 
If you have something like 1,2,3,4,5 as the output from the Matrix Value Receive actor, that will be text, and will be sent as text when sent via OSC.

You will need to unpack the text on the PD side, and convert each numeric Text element into a float there.

How many values are you sending? If its a manageable number, you can send a bunch of numbers over OSC by using the OSC Multi Transmit actor.
Another option (if PD can unpack JSON) is to bundle your data as JSON, and unpack on the PD side. 

@dbengali Hello! I couldn't replicate the issue with an Apple Pro Res 422 file nor a quick AVC codec saved via QuickTime Pro. I'm running on a MacBook Pro M2 / Tahoe 26.1 / Isadora 4.1.3

Hi,
I usually do the chases using a sequence of [wave generator] shifting the phase depending on the amount of fixtures in the chase. The limit-scale allows me to set the max-min intensities of the chase.

I also use a Javascript actor to automatically assign the phases: This is actually not really needed since it's generally a one time job and you can do it by hand.

I hope this was clear. Don't hesitate to ask if I was not clear enough.

Thanks, I've now logged this.

@kosmopilot

As far as I know, you'd only potentially have trouble if you intend to use the Screen Capture actor with Isadora 4 on Tahoe. We've not had any other reports of issues with Isadora 4 and Tahoe as far as I know. 

That being said, technically macOS Tahoe is not currently a supported operating system for use with Isadora 4. (This doesn't mean that Isadora won't work at all on Tahoe, it just means that we are still in the process of discovering what we need to update in order to unbreak the things that Apple broke for us in Tahoe.)

@dusx

Thanks!

@dusx Ahhh refine the hours even more...Have no tested it in 24 hours myself yet, since I have to use I in a 5 hour show only. Thanks.

 Yeah I've heard from reliable sources that NDI is on it's way out - moving to a paid subscription. 

 Thankfully I can confirm this is not the case. This summer, there was confusing messaging from NDI on this indicating that they may require commercial software to pay for a commercial license of their SDKs, but after the strong negative response, they immediately clarified that the free SDK is here to stay. CDN media

Hi,

Yes, those are the right modules to use. 

As identified, you will require a way to take the linear stream of numbers from the Matrix Value Receive across to the LanBox Channels inputs. To achieve that, in the Matrix Value Receive actor, I have specified a comma to separate the values (as in CSV), a script can then be prepared to return each value individually. Isadora offers a range of ways to implement scripts to parse data including with a Javascript. 

The Matrix Value Receive actor has an assignment mapping when you double click on it. It is there where you will correlate the channel input to the output stream.  

The Matrix Color Send has a video input and I have used the Get Video Size actor to return the pixel dimensions of the video stream (in my case 650 x 650 pixels). I am then using that information to determine the inputs for 'repetition' and 'spacing' of the 1 pixel rows indicating where the video is sampled for its intensity as an input 'grey', greyscale image.

I have prepared an example that resolves what you are doing with the Matrix Color Send module... here.

best wishes

opening and closing Isadora files

 I keep meaning to do something neat with this little guy. Some day, some day...

Somehow?  after years of using my ipad as a secondary monitor via Yamdisplay all i get is a white screen when i send stages to my iPad. 

But if i mirror my screen it works. Any Idea?

Thanks for this patch

 No problem. Hope you find it useful.

I'm using also M2 Ultra with 4 HDMI out and local one for monitoring. I just received a made in china video wall controller 1 in 4 out to see how that is performing. Have to test it first.

thank you for the answer. 

Glad to read that you have logged this as a feature request, it 's really important for people working with alpha channel... (and isadora is, in my opinion, really made for this !!!)

So i will keep working in prores 444 (just have to slow down on layer's numbers and glsl ...)

artoo.

@craigw

After a quick browse, I suspect these cards will just work with Isadora's blackmagicdesign integrations as they are.
