<p>I’m using stages setup </p>

 Have you watched this? 

Isadora is very fast at projection mapping, although it takes time. It is one of the best.

I am not sure what you mean by 4x3 exactly. 4:3 is an aspect ratio? Is there some confusion here? Or do you mean something else?

Also Stage Output is where you set up your outputs - not to do the mapping itself.

You can also see if changing the 'r/w mode' input on the Data Array to a different setting solves this for you.

@woland

Thanks for your advice on this. I have looked into what kind of investment would be required to go with a single  computer solution or Datapath FX4’s but the reality is the MacMini M4 is a much better value proposition at this time. With 3 x MacMini I am provided a total of 9 potential discrete video outputs and greater long term flexibility, while remaining well under the current price point of Datapath FX4. At this point It appears to me worth the extra fiddling around with Isadora programming. I do take the point about reducing the over all number of Movie Players, that is a great approach!

Best wishes

The input on the Broadcaster is mutable, meaning it will change to match the data type and range (if any) of the first output to which it is connected. Sounds to me like you've connected the Broadcaster actor to an actor that has caused it to adopt the range of the other actor like this:

Figure 1: Range of Wave Generator 'value' output property is min:0, max:100

Figure 2: Range for fresh Broadcaster actor's 'value' input is min:MIN, max:MAX

Figure 3: Once connected to the Wave Generator, the range of the Broadcaster actor's 'value' input mutates to match the range of the Wave Generator; min:0, max:100

I've tried deleting the media on prompt when closing the file, or using the Delete Captured Media button in the Output dropdown.

Dear All,

thank you for your answers !

Sadly, I have no skills for any of these solutions, and most of all, it's for live performance so it's already a mess to hold computer, wifi webcam and play in front of so we decided to skip this scene.

Btw thank you anyway !

Popopoooo, thank you JF and DusX !

It was super helpfull :) I have now the feddback that I needed, lessssgo to perform now !

If you post the original file I can take a look, but without that or more information there's not much I can do

Hi everyone,

I recently replaced a Christie lamp projector with a laser projector and kept the same Medialon integration. Previously, I used the TCP command HIS+LMP6 to retrieve and display lamp hours on the user interface. This worked perfectly with the lamp-based unit.

However, with the new laser projector, this command no longer functions and returns an error. I suspect that the laser model uses a different parameter for tracking usage hours, but I haven't found the correct command yet.

Has anyone dealt with this issue before or know the correct TCP command to retrieve laser hours or operating hours from Christie laser projectors?

Any help would be greatly appreciated.

@giel

Yes, the NDI HX camera is great.

Also EpocCam works well. But I prefer the NDIHX.

I wonder if Python could achieve a similar result?

 Python or Javascript, shouldn't have any problem with this.
Just restart a timer when a new value arrives, and have a pulsed trigger that has the time checked constantly, making updates as needed.

@donald

If you want to have more than two videos, you'll need to switch to some other setup. Something like this: Download (same file, just added a third Scene)

@tr742

No problem :)

Nice project. Glad it was a success.

Hi Alex,

I did something similar yesterday in Oulu Dance Hack, using a feedback loop through an Effect Mixer with a Video Delay. Super simple, but quite difficult to imagine the results.

The Video Fader controls how much of the image is fed back into the system. Zero gives you an infinite buffer, 3 or 4 gives a long fade out. 
Its particularly effective if you can control which bits of the image get fed into the system. I was using lighting in a dark space, but you can use something like Difference to split off part of the image and get it looping, then combine it back with the initial feed with an Alpha Mask or something similar.

Get Value and Set value

Get Global Values and Set Global Values

I find that best practice with this is to put the Set Global Values actor in a Background Scene if I only need to adjust the values via a Control Panel, then put the Get Global Values actors in my other Scenes. 

A big difference between Broadcaster/Listener and Set/Get Global Values is that a Get Global Values actor will push its values when you enter the Scene that contains it, but a Listener actor will only push data when the Listener and its corresponding Broadcaster are both in active Scenes and the value going into the Broadcaster is actively changing. Another difference is that Broadcaster/Listener actors can also transport video, which Set/Get Global Values cannot.

When in doubt about what an actor, or one of its inputs/outputs does, you can always right-click an actor and choose the top contextual menu option "Show Actor Help in Browser" to open a single page with all of the help text for the actor and its inputs and outputs. 

@dusxthis Thank you, this is helpful.
