Hi!

Am working with a Brompton Tessera processor and LED wall and 60 fps of framerate out of Izzy (wall is also set to 60). Am experiencing jitteriness and non-continuous/smooth motion when animating the position of a still image horizontally (same with jpgs or png). Am using the ease in-out actor to do a bit of horizontal position left to right.

Any thoughts? It's not a very fast speed of motion either. 

Thanks

I didn't think about the tip of simply hiding part of the name!

Well, you couldn't have because you didn't know it was a pixel limit and not a Scene Limit ;)

This issue is one that really annoys me personally, so once we have this next release out the door, I'll see what I can do about pestering one of the programmers to get this bug fixed.

@martinithyme

I swear sometimes posts on this forum are hidden from me because I check every day and never saw this until now. I don’t know what’s up with that…

Anyway, if you’re on Windows I’d suggest using ShutterEncoder and converting all your files to hap.avi. Sometimes video files can be exported with strange settings that Isadora doesn’t like (for example, embedded timecode tracks have been known to cause playback issues).

@bonemap

We brought this up at last week’s Thursday tech meeting and as of last Friday we have a beta build that contains a fix for it, so it’ll definitely be fixed for the next public release.

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.

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.

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!

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, I've now logged this.

@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

Best wishes Simon

@woland

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

@tarox

Any news on this issue from your side?

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.

@drpjm

Did you close and re-open Isadora? It won't remap the python environment until that is done. 
I assume you have watched these tutorials: Using the Pythoner Actor – Do More in Isadora with Python - YouTube

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. 

@citizenjoe nope. Playback still stops after a few hundred frames backwards..

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.

@tatrapikao said:

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.

@woland Thank you for update.
