I have a step back version but it's a whole day of work.

 Because I often work on things where I'm pushing Isadora to the absolute limit, I've gotten into the habit of making incremental saves every hour or two. I rarely need them, but when I do, I'm very glad to have them.

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

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.

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.

This seemed like useful information to share if you hadn't found this yet. 

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)

zzy is starting as a background process

 Generally, you just need to kill the task in Task Manager, and restart.
This can happen occasionally if you have other software that conflicts in some way. Very difficult to know what software that might be, perhaps something else creating openGL contexts. 

yes i have Nahimic

 If possible, update to Nahimic version 2, the issue was corrected in the new version.
If you can not upgrade, the only solution I know of is to remove/uninstall Nahimic cleanly.

Thanks @Skulpture and @Woland

After exporting several different file and codec combos, I realized that it was actually (maybe) a lag in my hdmi extender, which is old and not HDBaseT. I don't do a lot of this kind of content, so the lag was just much more evident...close ups of actors faces so the audio and video were just out of sync because of the lag.

Or at least that's my current theory. I ordered some new HDBaseT extenders and I'm hoping that will solve the problem. But I am using QT/Hap Alpha for the record.

Thanks, as always!

Jake

 Hmmm I am not so sure. HDBaseT is marketed as zero latency. Unless the hardware is faulty or there are other factors we aren't aware of. Let us know how you get on.

is this still broken in isadora 3

As Dusx said, we're no longer actively developing Isadora 3, but this issue is fixed in Isadora 4.

In the NVIDIA Control Panel there's a setting for power management, which I set it to prefer maximum performance and rebooted.

 Interestingly, I took another look, and the performance management utilities on my Lenovo Legion, automatically switches this based on my mode. So 'game' mode which I use for shows sets this to maximum.

NOTE: Python is not initialized in Isadora until a Pythoner actor is added to the project. You can update the 'environment activation file' and restart Isadora, and the Python Virtual Environment setting under the Help menu will appear GRAYED OUT & (Awaiting Activation) until the Pythoner actor is added to the project. 

Will it help to add a scaler or should I change the videos outside of Isadora?

 Re-exporting your media at a lower resolution then using that lower-res content in Isadora is less load-intensive for Isadora than scaling the content in real time inside Isadora.

Any news on this issue from your side?

Ok thank you very much

I somehow madd a work around but I will try and go back. Im sorry I was in the middle of production.

Thank you so much so far!

All the best

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.)

Thanks!

Would it be possible to adjust the behavior of isadora in a future update so that pixels on a display that are outside the boundaries of a stage do not pick up any pixel data from the edges of any stages that touch them?

Yes, I can log it as a feature request. It's certainly an interesting use case. I must say that I do find the stretched pixels kind of pretty though, and even know of Isadora users who also like this look and cause it to happen intentionally.

If you need help:

Yes, Ryan is our Windows specialist. As he said, the solution thus far for people has been to install older AMD drivers. The reason we can't tell you exactly which ones to use is because whenever people have had this issue they find the correct driver and then go back to working on their projects. (Meaning they don't tell us what drivers don't work and therefore we unfortunately don't have that information to provide to other users experiencing the same issue.)

If you'd work with Ryan in the ticket to figure out what drivers solve the problem for you, that would be very much appreciated.

You can talk to him about what version of the Adrenaline driver you're already using and what other versions are possible to try.
