I'm having an emergency. I have a whole show file that maybe has been corrupted by some bad files. I have a step back version but it's a whole day of work. The files that gave me error message are just jpgs which seems really strange...I've never had that happen before...is it usual. I also have one video file that seemed to be corrupt but when I removed it, nothing changed. The effect of all this was that the video feed was advancing, but the scenes in isadora weren't. So I was seeing something projected that was not on screen...and that seemed bizarre. And then the engine basically just froze. They're finishing a run (dress rehearsal) so I can't problem solve right now...but once I get my computer back can anyone suggest order of steps to quickly solve this problem. Do I need to step all the way back to the previous day's file?

Thanks

@woland Thank you L this is an alternative solution which I hadn't thought about. I'll check this out too. Many thanks!

Was that helpful at all?

@codyseehunt

you will find the Mac OS versions here:

scroll down to find 1.1 Update (Mac OS) and then click on Assets

The Enttec DMX control actor is a little difficult to set up, but if you have the correct channels set, then it should function in the same way as a lighting desk. The times when I had a problem controlling lighting through the Enttec was fixed by experimenting with different speeds in the Serial Port setup - sometimes the default speed is too fast for the device.

@filpi2

I'd recommend building your file using the OSC Address Listener actor.

That way, whatever tool you made to do this can be put into a User Actor and used in any file instead of being locked to this one specific Isadora file because of Stream Setup.

Thoughts? Explanations? Logic?

 It's showing the size of a blank character (space). Notice that if you leave the 'text' field blank or put a space in it, the text width/height doesn't change. Seems like a bug. I'll log it.

I can get around this using a limit-scale-value actor, but still curious as to why this is happening...

Here's another (admittedly more complicated) way (check the top right Comment): dynamic-subtitle-background-2026-04-24-4.1.3.izz

Sales & Licensing questions are better to ask using the support ticket link in my signature.

Our S&L staff don't use the forum.

@eight

I'm also going to log a feature request to move this to the Actor menu. Doesn't make sense that it's not with all the other actor-related show/hide menu options.

Could this be possible, to swich between multiple different videos and simply having one output?

Yes, quite easily:

Thanks

I'll see if I can update them, asap. 

In the meantime I found this post from Woland. 

"""

The newest version of the Rokoko Studio Live Watcher (which comes in the download for Isadora 4.0.7) and the newest version of the Rokoko Studio software should work with the v1 suit. 

The tutorial and actor that come in Add-Ons Page download for the Rokoko Studio Live Watcher should work if you need to use the legacy version of the Rokoko Studio Software for the v1 suit.

Either way, you will also need to get the first paid tier of subscription for the Rokoko Software in order to stream the data from their software to any other software. The "Plus" tier costs $20USD/month. 

If you run into any trouble just send in a ticket (link in my signature) and I can personally walk you through it since I have my own v1 suit.

Hi all

Many thanks for the pointers and info. Sorry for not getting back earlier, just the day it has being.

I think jfg has nailed it for me.

The Trigger Text actor seems to be what I seek.

I have been overthinking this. I, effectively, juat need a placeholder that allow me to have a one button entry for a set time which enables the streamdeck usage.

My custom timer has a countdown that works like a traffic light in terms of the colour warnings. I do a lot of death by powerpoint and I am looking to use the timer as a notification to the presenters.

By using the trigger text actor, I can set the placeholder for the time on the screen. This time may change from presenter to presenter and I am just looking to automate this via a streamdeck. Not all around me are familiar with Isadora (give it time!) etc. Previous to this, I was just editing the various sections on the patch. I now have other people coming into the workplace and this will allow me to populate the streamdeck with standard times, start, stop etc in the streamdeck.

I was confusing the issue with TC but JFG's suggestion got me thinking ref the trigger text. I have two items I wish to achieve, a placeholder and a countdown timer. I was looking at this process as one action rather than two actions if actually is.

I had a quick try out and in a rough manner it works. 

Many thanks all and I will gladly accept the award for the most obtuse query of the year.

Hopefully that explains my methodology.

Thank you

 Off topic: I've never heard of Brave Browser before - it looks amazing. Thanks, for the tip!

Bumping this thread - does anybody have some new ideas for a Slit Scan shader? or should we put in a feature request for a more flexible Slit Scan actor? (inputs for width of slit and speed would be nice, horizontal and vertical offset might be interesting)

Don't know what I did

 I would take note of which USB ports you are using, this likely is playing a role. (some USB C ports offer more features than others)

@eight said:

publishing an X offset of the input in the projector actor

 I believe this is working in this configuration, unless I miss understand. 

My input is 3000px by 1080px In IzzyMap, 

I move my rect to the far left and select each right side corner, and enter 1920 (this creates my 1920x1080 output selection) 

I right click the Rect slice, and publish the Offset X 

Then on the Projector, I can move my view from the left edge to the right edge. (-1 thru 1)

I'm currently working on a project using Rokoko and Isadora, and I wanted to try the tutorials from Guru Session #19. However, every time I try to open the tutorial file provided Isadora crashes. I don't know if this is because the files aren't compatible with my version of Isadora, or if it's because I don't currently have an Isadora license. I'm really hoping to work with a 3D puppet. Does anyone have any idea as to why this might be happening? Or any other way I could achieve the same results?  Any help is appreciated.

@charlotte_e

I would also suggest going the GLSL Shader route. LLMs can do pretty well if you feed them the contents of Tutorial 3 here and the guts of one of the existing TT GLSL shaders as an example, so that they can understand the formatting requirements.
